Could I just do this?
mysql_query("SELECT * FROM table WHERE id='$id'");
Yes. And if $id is always numeric you could simplify it even more. Quotes
are only needed around strings. They aren't needed around numbers. If you
surround a number in quotes it's treated as a string which will result in
different behavior when doing sorting and or comparisons.
mysql_query( "SELECT * FROM table WHERE id=$id " );

It appears as though the sprintf() function is being misused. There's no

Re: [PHP] Pricing for PHP programming???
"Shane McBride" [EMAIL PROTECTED] wrote: I was wondering what other PHP people charge to write PHP? There's no magic answer. And no offense, but if you categorize building business solutions delivered via the internet as "writing PHP" then your services probably shouldn't be priced at the higher end of the spectrum. There are so many factors - size of project, complexity, reusability of project components, turnaround time, your reputation, your speed, geography, etc. And there are many ways to price a project. We use a combination of flat rate pricing, estimates with a cap, hourly rates, retainer arrangements and some more creative terms depending on another long list of factors. As a PHP programmer and COO of a development and consulting shop, the emphasis on hourly rate is something that really amazes me. Not all programmers are created equal. A lot of clients don't recognize that. Some mistakenly believe that a $120/hr. programmer is 20% more productive than a $100/hr. programmer. Yet others think that a $200/hr. programmer must be twice as good as a $100/hr. programmer. I find that there is *no* correlation between hourly rate and the quality, productivity and value of a programmer. Sure, in other non_knowledge_based occupations, there may be a correlation, but in our biz I don't see one. Some say "you get what you pay for", but b/c this industry is new there are a lot of unscrupulous developers out there talking with naive uneducated clients. This is a dangerous mix. We've talked to a number of prospective clients who were charged $100,000+ for projects we could have done for $5,000. I couldn't sleep at night if we gouged clients like that and in the long run I think gouging clients will come back to bite you. We try to emphasize the total cost to the client along with the benefits of our proposed solutions. We try to state these benefits in terms of time savings, exposure, value-added capabilities, revenue and process improvement. When you can put what you can bring to the table in these terms the hourly rate becomes less critical and it makes it easier to compete with inferior competitors that compete on price alone. So, in general what should you charge based on your skills, experience and the types of things you are building? At a mimimum you should charge enough to cover the cost of your operation taking into account the risk of not staying fully utlized and adding on enough to make an acceptable amount of profit. If after arriving at that number it seems that your target market can't support that rate, reassess your strategy. As a rule of thumb, a consulting biz needs to charge 2.5 - 3 times the hourly rate payed to its employees. If you're a one person operation, you might think you need to charge less, but I wouldn't look at it that way. Unless you have clients breaking your door down and your clients aren't aware that there *are* others like you, you'll probably have to spend a significant amount of non-billable time dealing with running the business, doing marketing, sales and other business functions. And if you're alternative is working as an employee of another company and earning a steady paycheck (unless you just don't want to work for anyone else) you should plan on at least making enough to earn more than this alternative. If I was trying to gauge my value I would probably start low, build up word of mouth, client referrals and long term relationships and then increase my rates gradually over time if the market allows you to do so. In my area a green PHP programmer working part time might be able do contract work for $15 an hour while a seasoned guru might be able to command $150 an hour. Over time your programming skills, productivity and business knowledge should continuously increase. As a result your margins should increase, even if your so called "hourly rate" remains flat. Unless of course you hire other people. That may make your operation much more complex and difficult to manage than you may think. Plus, any development firm that hires a PHP programmer is reducing the pool of PHP programmers available to my company and I just can't have that. grin -- Steve Werby COO 24-7 Computer Services, LLC Tel: 804.817.2470 http://www.247computing.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] Automatic incoming mail notification
"Josh G" [EMAIL PROTECTED] wrote: Depends on your mailserver. Most mail servers can redirect incoming mail to a program, I know sendmail can. In your case just make the first line of your script #!/path/to/php/bin/php and that should do the trick. To actually read from the message piped to the PHP script, you'll need to use the following to read from STDIN: fopen( 'php://stdin', 'r' ); The above isn't widely documented, but it works. With all this said, if the original poster simply wants to let a web-based user know that there is a new message in the user's email box, a better strategy may be to store all of the messages in a database like MySQL and compare the timestamp on the most recent message to the timestamp in a session variable from the previous page access. It wasn't clear what the poster was attempting, but with some more details someone (maybe me) could provide a good solution. Also, PHP has functions for accessing IMAP accounts which could prove useful. Sorry I don't know how to make sendmail do it, only that you can. Using sendmail you add an alias to pipe incoming email to a program (your PHP script). You may also need to create a symbolic link in a directory utilized by smrsh (sendmail restricted shell) to allow sendmail to execute your script (this is done for security reasons).

Re: [PHP] Performance question
"Matthew Mundy" [EMAIL PROTECTED] wrote: I was wondering. What kind of performance reduction is there in including files or using the auto prepended one for a file less than, say, 10 line? Specifically, I would think that the file IO would be a detriment to such a small file. Without the includes, code would be repeated, but in PHP, IMHO, speed is a much more important factor than code size. Anyways, what would be the performance factors in deciding what goes in an include vs inline code? I don't think you'll find a noticable difference in speed. To me the benefit of a modular design outweighs the effect on speed. As a rule of thumb, I take any code that will be used in multiple files and store in a separate file, but development speed is my most critical constraint. Reduced file size is a nice side effect, but storage space is so cheap that really doesn't matter. And if you want to increase the speed from the user perspective you may want to look at a combination of caching and sending gzipped data to browsers that support it. There was a tutorial on phpbuilder.com recently about this strategy and with the exception of a few obstacles it works nicely depending on what your output is like. You might want to benchmark including the code inline versus using include() or auto prepending it by writing a program to simulate expected (or heavy) usage of the script in question and using something similar to the code below to track the time that the script took to run. On small simple programs the results will be skewed by the time it takes to actually run the code below, but on longer, more complex scripts that will be neglible when comparing your test cases. ?php // Set start time of script. $time_start = microtime(); $time_start = explode( " ", $time_start ); $time_start = $time_start[1] + $time_start[0]; // Set end time of script. $time_end = microtime(); $time_end = explode( " ", $time_end ); $time_end = $time_end[1] + $time_end[0]; // Measure script run time. $time_run = $time_end - $time_start; // Write output to file. // Left as user exercise. ? -- Steve Werby COO 24-7 Computer Services, LLC Tel: 804.817.2470 http://www.247computing.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Yes, some guys who charge only $10/h might sometimes be better than $200/h, but you cant say that there is *no* corralation between rates and quality. Sometimes there actually is. $10 versus $200 is a little extreme, but I agree that there is sometimes a correlation between rates and quality if we're talking about programmers or firms that deal with larger, better educated (in terms of software development) clients. If we're talking about individual programmers that deal with smaller clients I don't find this to be the case. Because smaller clients tend to understand the technology and the process less and often can't recognize the difference between a guru and a hack. I usually dont charge for hour either, rather per project, but your example of $5000 and $100,000. Well, what is the purpose of your doings? Many of us like what we do, but the second reason (if not the first) for doing it, is money, you can say whatever you want, but this is true for mosy of the peops. Obviously I want to be profitable. But my primary motivation is to be doing challenging work, to enjoy what I'm doing and to build software that makes my clients happy. Sure, we could be like this other company and charge $100,000 for a project that's worth $5,000 but we won't do that. Why? Because it will inevitably come back to haunt us. In this business you have little more than your knowledge and your reputation and a tarnished reputation won't get you far. YMMV. And lets talk about clients just a bit more. A decent firm, before it starts buying something, it looks on more than one direction, they make their job on getting to know the prices and services that are being offered to decide where to order something. Again, I think we're talking about different kinds of clients. A large corporate client looking for someone to fulfill a large project will spend a lot of time doing research, soliciting quotes and in general will be well educated in terms of what's involved and what it should cost. A small brick and mortar company or shoestring budget startup headed by a non-technical person might not have that luxury and generally doesn't have the time, energy or expertise to make a qualified decision. My experience is that a lot of these type of clients only speak to 1 to 3 firms. And these other firms are often not qualified - they don't understand the business world or don't even do programming. In fact, last week I spoke to the head of a small internet startup that was soliciting bids for a search engine for his site. His site consisted *entirely* of hundreds of identically formatted static pages that were created by combining text and images in Photoshop. He got bids from 2 other firms before me about building a search engine for the site. We were the only firm that informed him that no search engine can search text from within an image (meaning the other firms had no clue) and that if we built him a database driven site with an admin interface to upload images, create records and modify text he could save 15 minutes per page built for the site and modify the entire look of the site in under an hour. Based on his projection this would save him about 300 hours a year. These are the type of clients we typically deal with 80% of the time. We're comfortable doing it, but we don't rip them off just because they're uneducated. $100,000 instead of $5000? You shouldnt. In some other fields you could say that they just didn`t have any other candidates to choose from, but when talking about programming and php, well, you just can`t say it, can you? Most of the projects can be done even over the internet, no problems. My reality is different than your reality. I don't know if I want to trade places or not. grin shouldn`t count on all the jobsites available in the internet, rather word of mouth, this is the best way. Amen.

There are plenty of situations where it's useful. For example, if you're
displaying data in rows and want to shade every other row:
if ( 1 == $row_count % 2 ) { echo "trtd$data/td/tr"; }
else { echo "trtd class='shade-1'$data/td/tr"; }
Or if you have a data set you want to display in an HTML table across
multiple rows, you'll probably find it useful for determining when to put
tr or /tr as you loop through your data set and use it to calculate
whether you will need to fill cells at the end of the table with
non-breaking spaces. There are many other applications, but these two come
up pretty frequently in web applications.

I'm not certain, but cadduser seems like the name of a script to add a user to Linux from the Cobalt RaQ3/4 shell tool package so you're probably running PHP as an Apache module.

Re: [PHP] Search Engines
"Joe Montiel" [EMAIL PROTECTED] wrote: I am new to the list and to php...I would like to know how php does with the major search engines. Do I need to do something extra to make it work? Will it index if I am pulling my content from text files? PHP produces HTML output which is sent to a browser, spider, etc. Everything else being equal about content on a webpage, a PHP generated file and a static HTML file are identical, with the possible exception of the file extension. There are a few "gotchas". A search engine can recognize a .php* file extension and assign it a penalty, though I'm not aware of this happening. If that's a fear you can always configure your webserver to parse .html files using PHP. Some search engines will ignore or penalize webpages with query strings in them (query strings are variable-value pairs following a "?" after the webpage name). The logic for this makes sense since a lot of pages like that are dynamically generated and a search engine will be less effective if it indexes a page and a few days later a user does a search, it appears in the results and the user goes there and the page no longer exists or contains different content than was indexed. An easy way around this (at least in Apache) is to create dynamically generated webpages that appear static. This can be accomplished by using AliasMatch lines in your Apache config. file to point a group of URLs (such as all beginning with '/books/') to a single PHP file. Then within the PHP file use a combination of regular expressions and environment variables (among other solutions) to pull the proper content from a file or database. For example if you have a URL like '/books/516.html' you can do: eregi( '^/books/(.*).html', $SCRIPT_URL, $regs ) ) // $regs[1] will contain '516'. // Grab record from database with id 516. Offhand, the only other things to watch for are don't do fast meta redirects (or any redirects at all) and if your PHP file hasn't been updated in months, but the database data it pulls from has updated recently, it's likely that browsers and spiders may think their cached copies of your webpage are current. A solution is to use a combination of header() functions like: header( "Last-Modified: " . gmdate( "D, d M Y H:i:s" ) . " GMT" ); Making your webpages appear at the top of search engines for your desired search phrases is another story. Though I live talking about search engine optimization strategies and steps, this isn't the right forum for giving away all of the secrets. smile -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Here's some personal insight to consider. This will work and I toyed with it in the past. There are a few gotchas: 1. For a valid host, if DNS is slow it may add several seconds to the script. 2. If it's not a valid host, the script will run until the lookup times out. 3. If the host is temporarily down or inaccessible it will falsely report that it doesn't exist. So it really depends what you're trying to do. Only thing left is whether or not the user exists on the given mailserver. But for as far as I know you can't automatically check that.

It sounds like you're basically asking why one would want to use a relational database. Standardization, speed and flexibility for starters. MySQL and many other databases use the SQL language for accessing db data. If your dataset is large a SQL statement to return records from indexed tables will be much faster than code at the application level. And a relational database allows you to store data in separate logical tables instead of one large table - for example tables of products, inventory, customers and orders. Using SQL to query these tables to find out something like the quantity and total revenue of widgets sold in August to customers in New Jersey whose company name begins with R would be much easier with a relational database than 1 or more text file datasets. There are many other benefits, though that's not to say that text files aren't sufficient for your current needs.

Place 1 - show details for record 3
Place 2 - show details for record 1

Someone mentioned saving to an array. That's the way to go, but I'm not
sure if the reply was clear.
$i = 1;
while ( $qd= mysql_fetch_object( $rs ) )
{
if ( $i == 1 ) { $var1 = $qd-my_field; }

...
else if ( $i == 5 ) { $var5 = $qd-my_field; }

Then use $var1, $var2, ..., $var5 where needed after the loop finishes. I
may be misunderstanding, so if you really want your query to return 5
records, but want to randomly pick a record for each of 5 random spots on
your page then do this:
$i = 1;
while ( $qd= mysql_fetch_object( $rs ) )
{
$var[] = $qd-my_field;
$i++;
}
Then use array_rand() inside a loop to pull from $var[], removing each
element after it's selected (more efficient) or adding code to ensure the
same element isn't picked twice (less efficient).

Re: [PHP] Re: Submitting variables via /'s
Matthew Walker [EMAIL PROTECTED] wrote:
So, can someone give me the spot to look in the documentation to find
out how to make this switch?
There are multiple solutions. In a nutshell here's what I do. I add
directives to the VirtualHost block for the site which point web requests
for certain pages to a master script that generates a number of pages with
similar database-driven content. Here's one such line. Any file beginning
with photo_gallery_, followed by 1 or more digits and ending in .html is
handled by template_1.php.
AliasMatch ^/photo_gallery_[[:digit:]]{1,}.html$ template_1.php
For this particular site, template_1.php actually handles nearly all of the
web requests for the site. It consists of HTML code generating the basic
physical appearance of the site, then calls other scripts to generate the
HTML head section, breadcrumb trail, etc. and uses an include() statement
to load the appropriate PHP script that generates the bulk of the page's
content. In this case that script is inc_page_news.php.
In inc_page_news.php the following code extracts the page number:
ereg( '/news_([[:digit:]]{1,}).html', $SCRIPT_NAME, $regs );
if ( ! empty( $regs[1] ) )
{
// Set page number.
$page = $regs[1];
}
Then a database query is performed to extract and build the page content. I
wrote about the topic a while back on this list. If you're interested see:
http://marc.theaimsgroup.com/?l=php-generalm=98618455619989w=2
A few months ago I wrote a script that controls ~40 product pages on each of
about 35 sites using PHP/MySQL and Apache mod_rewrite. Prior to that the
pages were static and changes were done manually which was an extremely long
process for those involved (imagine changing layouts and fonts on 1,000+
static pages with no CSS). Now changes can be made across all sites,
products or combinations thereof in seconds. Sites, products, images, meta
tags, image tags, etc. are now entirely administered through a web interface
I built. Using AliasMatch in Apache as I described above all product pages
are handled by a single PHP script which parses the URL for the site name
and product name and pulls data from a number of tables and handles a few
special cases programmatically, then generates the page. Here are a couple
of the URLs. You'll notice they aren't the prettiest of pages, but the goal
was to drive traffic to the sites from search engines, convert a high % of
visitors to sales and allow the site to be administered by a non-programmer
and implement changes rapidly.

Well now, I didn't say I was only doing INSERTs. Best guess based on limited information. My bad. :-) After parsing the email, I need to do a quick select in the DB to see if the customer (placing the order) already exists in our DB, and if they don't, just plain INSERT. Otherwise, I need to do some more work, which will require an UPDATE on that same record. It sounds like the only possible conflict is if a customer not in the system places two orders that arrive at about the same time and the second SELECT is done before the first INSERT is committed. Experience suggests this isn't very likely...so unlikely I wouldn't even worry about it unless there's a reasonable probability that INSERTs would take a long time and new customers would fire off two orders at the same time (double send in Outlook or refreshing via a web form?)...and since I don't have all of the details and I'm likely misinterpreting the whole application I'll leave it at that. I'm probably going to break the DB into separate tables (one containing the customer info, with a matching ID in another table which contains the customer orders). FWIW, that's how I'd approach it.

You could use something like John the Ripper, which is a password cracker you can install on the server.

If there's a match it notes the cracked password. It's good for detecting weak passwords and can actually detect them very quickly, but if the passwords are strong then it's not effective for your purposes (that's a good thing) since by the time it cracked the password (if it did) your user would have likely taken their business elsewhere.

I've seen other sites achieve the same functionality by loading the elements of the second, third and fourth select boxes into javascript arrays which and regenerate the contents of the dropdown boxes and make them visible based on the element selected in the parent select box. This avoids a page reload, but forces the page to load all of the possible select box elements when it's first loaded - and it obviously requires javascript. It might be a good alternative depending on your needs. I've found that it only makes sense when very few target users will have javascript disabled and the potential contents of the select boxes are less extensive than make and model detail. -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Bill,
You need to declare the variables global within each function that access
them or access the variable via the $GLOBALS array.
$var = 'something';
function go()
{
return $GLOBALS[var];
}
or
function go()
{
global $var;

Sorry, substitute folder for Group. I just wrote that by mistake.
Data is such:
1 | friends | name1 | yes

3 | friends | name3 | yes
4 | work| name4 | no
I want to extract the ones approves, but list them by Group first, and all
the relevant names after. But I dont want to run a query for each GROUP to
output the data underneath it.
You don't need to GROUP the records b/c you're not performing any kind of
aggregate operation on them. Use the following query:
SELECT group, name
FROM tablename
WHERE approved = 'yes'
ORDER BY group
Use PHP to loop through each record like you normally would. Since you want
the group on a line by itself and then all of the names that are members of
the group one per line below it you should do something like the following
(I assume you're outputting in HTML, if not replace all 'br' tags with
\n):
while ( $row = mysql_fetch_array( $sql ) )
{
$group = $row['group'];
$name = $row['name'];
if ( $group != $group_previous )
{
echo $group . 'br';
}
echo $name . 'br';
$group_previous = $group;
}
By setting $group_previous equal to $group *after* looping through each row
it can be compared to $group so that you only display the group name when it
doesn't match the $group of the previous row. I think this is what you
wanted. If I misinterpreted what you were trying to do let me know.

Your logic is correct. If the code within the braces isn't working it's
likely there's either an error in the code within the braces or $date and

It would be helpful if you post a list of the range of phone numbers you are

by saying that I think you're regular expression is saying beginning with
anything, then exactly 3 numbers, then anything, then exactly 3 numbers,
then anything, then ending in exactly 4 numbers. Changing a {3} to {3,4}
would mean match 3-4 occurences of what's to the left. Hopefully that
will get you started, if you post some other numbers you want to pass
validation we can be of more assistance. regex are very powerful and I
recommend you add them to your training. That said, people enter #s in many
different formats and sometimes it's necessary to enter a # like
011-817-972-1086 x103 or 817-972-1086, 1, 3, 12 if you're dealing with
business numbers with extensions or automated systems that have to be

FYI, to break a string into an array like you describe use strlen() to get the length of the string, substr() to pull out the first N characters from the string, then loop through and add each element to an array by adding as follows (pseudocode): for ( $i = strlen( $string ); $i = 0; $i-- ) $array[] = substr( $string, 0, $i ); -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Like Tom said, use regex to check the email is of a valid format. A small percentage of servers can be contacted to find whether an email address is valid, but fewer and fewer are allowing this so it's completely unreliable. You can use getmxrr() to see if a DNS MX record exists corresponding to the domain. You'll need explode() to pull out the domain itself from the email address. Unfortunately an email address can be valid without having a valid MX record and also DNS could be unreachable at the exact moment your requesting it. It might be better to bypass getmxrr() and use checkdnsrr() instead to find whether the host exists. Of course this too could be unreachable. If you really want to determine if an email address is valid, a better strategy may be to send an email to the address with a unique string in it that must be mailed back or a unique URL that must be visited. You'd then need a script that's triggered upon receipt of matching emails and changes a flag in your DB record to designate the email address as valid or a script in the webpage that does the same. -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Imagine someone passing in

Excellent point. In addition to hardcoding the path I would do something to
ensure that the file requested does not attempt to bypass that directory.
I'd probably use a regex to make sure it doesn't include a / or if I want
to serve files from a deeper directory I'd do a regex or use something like
strstr() to see if .. is within the filename. Personally, I wouldn't make
a script that outputed a file on the server or a script's code *and* allowed

So if a teamname never got entered in owners or the ID was mis-entered your query would not return all of the records from teampages and you probably want it to.

FYI, in sendmail both commands can be disabled by making sure PrivacyOptions is set as follows: PrivacyOptions=noexpn novrfy Or you can set them to the following which goes a little further: PrivacyOptions=goaway So unfortunately vrfy will only be useful when checking servers that haven't disabled that command. :-( -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
Re: [PHP] Running PHP as a cron job....
Michael Hall [EMAIL PROTECTED] wrote: With all the advice that has been offered so far, has it been assumed that php is installed in the CGI rather than DSO manner? I haven't found this to be clear from the thread. Can PHP as a DSO interpret shell script-like files with a shebang at the top? No. This only works if PHP is compiled in stand-alone (CGI) mode. Alternatively, I've read somewhere about using lynx to run a .php cron job. Does this apply to DSO setups? For example, would James put something like this in his crontab: * * * * lynx mail.php Almost. Instead of the filename, the *full* URL is needed. If PHP is compiled as an Apache DSO the only way Apache can parse the PHP script is if the file is accessed via the webserver, not directly off of the filesystem. If anyone goes this route I strongly suggest adding authentication via an .htaccess file and passing the user/pwd to lynx (see man lynx) so that your script which is probably only intended to be run via cron isn't available for anyone on the web to access. -- Steve Werby President, Befriend Internet Services LLC http://www.befriend.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
