Hi Suresh
Unfortunately you cannot call a javascript function from directly within
php. What you are doing is generating a web page that has invalid
javascript. Try looking at your output with view source for clues.

This is not a php problem, php produces a text file which is interpreted
by the browser as html and javascript. Have a look at your
html/javascript (view source) and figure out the problem. The use of
php is completely incidental.

[PHP] Slow query-building function
Hi,
Last year I switched from using FileMaker Pro to MySQL. One of FileMaker's
quirks was that if, in a text field, you searched for say, 'free ass boo',
it would find any records with those three substrings in that field (in this
example, its 'Free Association Books').
I want to have this quirkiness on my site, along with the option of adding +
or ! before substrings.
I've got it working using the following function:
function sql_fltr($sql,$field,$input){
$input = addslashes($input);
if(strlen($input)0){
if(substr_count($input,*)0 || substr_count($input,!)0 ||
substr_count($input,^)0 || substr_count($input,+)0){
$output=;
/* search for substring conditions */
$tempy = str_replace( +,|+,str_replace( !,|!,str_replace(
*,|*,str_replace( ^,|^,($input);
$temp = explode(|,$tempy);
$i=0;
while($i sizeof($temp)){
if(substr($temp[$i],0,1)==*){
$temp[$i]= and .$field. LIKE
'%.strim(str_replace(*,,$temp[$i])).%';
$output.= $temp[$i].|;
}elseif(substr($temp[$i],0,1)==!){
$temp[$i]= and .$field. NOT LIKE
'%.strim(str_replace(!,,$temp[$i])).%';
$output.= $temp[$i].|;
}elseif(substr($temp[$i],0,1)==+){
$temp[$i]= and .$field. LIKE
'%.strim(str_replace(+,,$temp[$i])).%';
$output.= $temp[$i].|;
}else{
$temp[$i]=and .$field. LIKE '%.strim($temp[$i]).%';
$output.= $temp[$i].|;
}
$i++;
}
$output = strim(substr($output,0,strlen($output)-1));
if(substr(strtolower(strim($output)),0,3)=='and'){
$output = str_replace(|, ,$output);
} else {
$output = substr($output,4,strlen($output)-1);
}
/* search for whole string conditions */
} elseif(substr($input,0,1)==*){
$output=$field. LIKE '%.strim(str_replace(*,,$input)).%';
} elseif(substr($input,0,1)==!){
$output=$field. NOT LIKE '%.strim(str_replace(!,,$input)).%';
} elseif(substr($input,0,1)===){
$output=$field.='.strim(str_replace(=,,$input)).';
} else {
$input = str_replace( ,|,$input);
$output =;
/* search for all substrings */
if(substr_count($input,|)0){
$temp = explode(|,$input);
$d=0;
while($d sizeof($temp)){
$temp[$d]= and .$field. LIKE '%.rtrim($temp[$d]).%';
$output.= $temp[$d].|;
$d++;
}
} else {
$output=$field. LIKE '%.rtrim(str_replace(|, ,$temp)).%';
}
}
} else {
$output=;
}
if(substr(strtolower(strim($output)),0,3)=='and'){
$query = str_replace(|, ,$output);
} else {
$query = substr($output,4,strlen($output)-1);
}
$output = str_replace(|, ,$query);
return str_replace(and and,and,$output);
}
For info the strim() function combines ltrim() and rtrim().
My usage example is:
$sqlp = select supplier_id from suppliers where (supplier_id0 ;
$sqlp.= sql_fltr($sqlp, 'imprint', $pubname);
$sqlp.=);
echo brbrbr.$sqlp.brbrbr;
I just add extra sql_fltr() lines for additional fields.
The main problem with this function is that takes 12 seconds on my XP
laptop, to build the query (I'm not even hitting the DB, but pasting that
into my DB front end gives a quick result.
I'm running PHP5.1RC on the laptop (PHP5.0.2 on my server) - both with
Apache 2.
Can anyone suggest a solution that will improve performance while retaining
the functionality?

Re: [PHP] Generating thumbnails from tiff images
Jay, I am not quite sure if you've made sarcastic comments but to make things more clear... I'd like to use GD instead of ImageMagick beacuse I would not want to install extra packages if I can. When I mentioned that I use convert I said 'when GD is not available...' So I have alternatives: if there is no GD support go with ImageMagick. If there is support use GD.

Re: [PHP] storing single and double quote in MySQL
I have an access as root user to the server and it shouldn't be a problem to turn Off magic quote, but I really CANNOT do it right now because, as I said earlier, just put live our new (pretty big) web site and there is no chance to put it again under construction for a next couple of weekls (redo site and test it again). As far as I can see, the only solution is make on extra server whole thing and then, once it's finished and tested, replace the old one? Also, there is a lot of info with slashes i DB - that has to be cleaned too, right? But, as sombody mentioned earlier, the whole php development goes in that direction (like global's Off/On before) and one day I will have to do it anyway. But, at least I can wait for version 2.0 of the web site :).

Get your variables, like 'area', from $_GET if they're not in $_POST.
And then you can change your page navigation links to something
like:
echo $pager-get_prev('a href={LINK_HREF}area=' . $area . '
title=Previouslaquo;/a');

[PHP] Monitoring Remote Server Services using php !!!
Hi everybody,
I'm new to the list and also new to php, I hope I can learn many
things from here.
My first doubt is the following: I'm trying to create a small monitor
system, just to suit my needs in monitoring some services in my application.
I've found some functions that return to me the service by port, name and so
on (getservbyport, getservbyname). What I need is to monitor remote server
services, I mean, lets suppose I have a server 192.168.0.2 with a ssh server
running. I'd like to see the status (up/down) of that server from another
machine, like 192.168.0.1. I don't want to use some monitoring softwares out
there in the web, i know they exist and in fact I use many of them like
nagios, cacti and so on, but I'm planning to do my own small solution.
What I need is some function that asks me a remote IP, port and
protocol as input data and results TRUE/FALSE (any boolean value), just to
see if the service is up. I did that making a function using nmap, but i
don't want to hold that solution to linux, I'd like to use it at other OS.
My function's syntax is like this
?php
$ssh_status=service_status (192.168.0.2, 22, tcp);
if ($ssh_status==TRUE); {
echo Service UP;
} else {
echo Service DOWN;
}
?
Does anyone know if there is a similar function in PHP ? I'd be very
happy if somebody knows about a function like that.
Thanks in advance
att.

running. I'd like to see the status (up/down) of that server from another
machine, like 192.168.0.1. I don't want to use some monitoring softwares out
there in the web, i know they exist and in fact I use many of them like
nagios, cacti and so on, but I'm planning to do my own small solution.
What I need is some function that asks me a remote IP, port and
protocol as input data and results TRUE/FALSE (any boolean value), just to
see if the service is up. I did that making a function using nmap, but i
don't want to hold that solution to linux, I'd like to use it at other OS.
My function's syntax is like this
?php
$ssh_status=service_status (192.168.0.2, 22, tcp);
if ($ssh_status==TRUE); {
echo Service UP;
} else {
echo Service DOWN;
}
?
Does anyone know if there is a similar function in PHP ? I'd be very
happy if somebody knows about a function like that.
No such function exists.
You should check out http://www.nagios.org - it's not php but it does
what you want.

[PHP] PHP halts after calling non-existing socket
After calling a non existing socket PHP halts and doesn't return. It happens when we do it through our web server (AppWeb) or through the command line. The problem is with socket_recvfrom. (see code below) Is this a known bug? a mistake I make in accessing sockets? installation error on my side? Thanks. Code: ?php unlink (/tmp/local_domain); $addr = /tmp/main_adaptor_sock; $socket = socket_create(AF_UNIX, SOCK_DGRAM, 0); if (!$socket) echo problem in creating socket; if (!socket_bind($socket, /tmp/local_domain)) echo problem in binding socket; $buffer = Update; socket_sendto($socket, $buffer, strlen($buffer), 0, $addr); socket_recvfrom($socket, $buffer, 100, 0, $from); echo message recv $buffer \n; ?

[PHP] str_replace(), and correctly positioned HTML tags
PHP list, This may be a simple matter. Please feel free to tell me to RTFM if you can direct me to exactly where in the FM to R. Or, alternately, please use simple explanations, as I'm not an experienced PHP coder. I'm building a simple content management system, where users can enter text into a web form. The text is stored in a MySQL database. The text should be plain text. When the text is retrieved from the database for display, I want to add some HTML tags so I can control the format with an external CSS. I'm assuming the best way to do this is with str_replace(). But there are some complications which make me unsure of its usage. First, here is the code I initially made: $content = p . str_replace(\r\n, /p\np, $text) . /p\n; echo $content; The problem is that I want to give the users the ability to add text that will be converted to h3 tags. I figure the best and easiest way to do this is give them some text markers, like --++ and ++-- that can be converted to h3 and /h3 respectively. So I guess I do: $content = str_replace(--++, h3, $text); $content1 = str_replace(++--, /h3, $content); $content2 = p . str_replace(\r\n, /p\np, $content1) . /p\n; echo $content2; But of course a user is likely to put their h3 heading at the beginning of their text. Which would generate: ph3Heading/h3text text text/p That's not good. What I need is: h3Heading/h3ptext text text/p And figuring out how to do that was where my brain stopped. I need to be able to account for circumstances where it may not be appropriate to arbitrarily put a p tag at the beginning. As well as h3 tags, there may also be things such as images and hr lines, but they are all similar in that they will take some text code and convert into an HTML entity.

Is there a good tutorial available? Any advice appreciated. Thank you for taking the time to read this. -- Dave M G It seems like your life would be a lot easier with break takes instead of paragraph tags. Break tags behave like newlines, so work rather well for a 1 to 1 correspondance when turning \r\n into br /. This way, you don't have to worry about the opening tags. The fastest way to do this may be the function nl2br(), which takes only one parameter, your string, and returns your string with the newlines replaced by break tags. Another piece of advice is that you are creating a lot of strings. Do you need the string $text to be unmodified? Why don't you do this: $text = str_replace(--++, h3, $text); $text = str_replace(++--, /h3, $text); $text = p . str_replace(\r\n, /p\np, $text) . /p\n; echo $text; Remember that PHP works by value, not by reference. So what happens in that first line is that it makes a copy of $text, does the replacement on that copy, and then overwrites $text with that copy. With your method you are creating a bunch of strings that I would imagine go unused later in your script. Since you seem to want to maintain a newline in the HTML source, nl2br might not be exactly perfect for you. Here is your original code modified to work with break tags: $text = str_replace(--++, h3, $text); $text = str_replace(++--, /h3, $text); $text = str_replace(\r\n, br /\n, $text); echo $text; And here is the same code using arrays and one single replace instruction to do it, since replacement order doesn't matter: $text = str_replace(array(--++, ++--, \r\n), array(h3, /h3, br /\n), $text); echo $text; And of course, if you never do anything with your formatted string except echoing it out, don't store it, just echo it: echo str_replace(array(--++, ++--, \r\n), array(h3, /h3, br /\n), $text); So, to sum up my advice: 1) Don't create extra variables that you will never use 2) Consider using break tags instead of paragraph tags, they're easier to deal with in your situation. 3) Use arrays for replacement when appropriate 4) Don't store data if you're only ever going to echo it out right away and never use it again. I think that's it, unless I missed something. Regards, Adam Zey. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

In any event, I think this is where you're going wrong -- don't use str_replace() to alter the *content* at all ! If you know css, then keep the content separate from presentation. Content comes from your mysql and you should be able to place it within html markup where its presentation is controlled by css. For example, if I have a text paragraph ($my_paragraph) that's been pulled from mysql and I want to show that paragraph in html, then I would do something like this: div=content p ?php echo($my_paragraph); ? /p /div That way I use use css to control how that paragraph will look with those div and p tags and, at the same time, make the content easy to handle. If you want to allow users to enter html tags themselves, then you're asking for a bit of trouble IMO because you are relying upon them to do the mark-up correctly. For example, if someone entered h1This is what I want to say/h1 -- how would you handle it? Also note that if that was entered as-is your page would not longer be well formed and would probably cause problems with the rest of your page, not to mention not validating. If you think you can write code to fix their mistakes, then I think that's a mistake for users can screw up code even more than programmers can. :-) Additionally, if you don't handle the input right, then there's a security concern, such as mysql injection. If you want to give your users the option of having headlines and body of work, then provide a Headline box and Body of Work box and then manage those entries in your markup. I think you get the idea. I'm sure there are other ways to do this, but this is the way I've done it. hth's tedd -- http://sperling.com http://ancientstones.com http://earthstones.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I know I'm entering this discussion a bit late, but one tool that I've found indispensible in writing regular expressions (even after knowing how to write them) is The Regex Coach (http://www.weitz.de/regex-coach) (Free, and runs on Windows and Linux). Essentially, you paste the text to search into the bottom textbox, and then start typing your regular expression into the top one. As you type, it shows you what it is matching in the bottom one. It can also show you what individual submatches are matching, and all sorts of neat stuff. So, if I have an HTML web page and I want to suck some specific information out of it, I'll paste the information in, write up a regex, and make sure it's matching what it's supposed to. But the feedback AS you're typing it is super handy. For example, if I have a regex, and I add a [a-z], then the indicator will show it matching the next character, then if I add *, the text selection will expand to show it matching the rest of the letters, and so on.

You know you can switch the php parser on and off like so:
?php if (isset($var)) { ?
form action=myform.php method=post
?php } ?
which is a bit more efficient and better than all those echo statements and
escapes?

Re: [PHP] Filtering (was storing single and double quote in MySQL)
As you said: Filtering. My next queston.
I have small form to activate/deactivate member's account.
form method=post action=members.php
input type=hidden name=username value=?= $Usename ?
input type=hidden name=status value=?= $Status ?
input type=image name=action value=change src=images/status_live.gif
border=0
/form
and once adminisrtrator clicks on button:
if(isset($_POST['action']))
{
$Username = $_POST['Username'];
$action = '';
switch($action)
{
case 'change':
mysql_query(UPDATE members SET status='live' WHERE Username =
'.$Username.');
break;
case 'edit':
// ...
break;
}
}
Do I have to filter $Username with mysql_real_escape_string() function
even if $Username will not be stored in DB and I use it in WHERE part?
If no - how to filter it?
Thanks

No, that's NOT filtering input, as per Shiflett's book.
Filtering input is proving that the data coming is -- IS -- valid data!
Take for example the code he shows on page 11 of his book (Essential
PHP Security) where:
?php
$clean = array();
switch($$_POST['color'])
{
case 'red':
case 'green':
case 'blue':
$clean['color'} = $_POST['color'];
break;
}
?
If you inspect this code, you will see that the array $clean will
never have anything in it that's not 'red', 'green', or 'blue' --
that's filtering input as per Shiflett.
And, that makes prefect sense to me.

Yes, you're sending it into the DB which means it is a command that
needs to be escaped. All MySQL commands need to be escaped.

Always sanitise data provided externally; whether it's from the user
directly (e.g. a POST form or a URL query string (GET)) or from the browser
(e.g. cookie data)... always assume it can never be trusted (there are some
nasty people out there)
In this case using mysql_real_escape_string() on the supplied username
should be enough for most injection attacks (
http://www.google.co.uk/search?hl=enq=sql+injectionmeta= ), but to be more
sure try this (if your username is alphanumeric only with spaces):
if(isset($_POST['action']))
{
$Username = preg_replace('/[^a-zA-Z0-9]+/', '', $_POST['Username']);
$action = '';
switch($action)
{
case 'change':
if (!empty($Username)) mysql_query(UPDATE members SET status='live'
WHERE Username = '.$Username.');
break;
case 'edit':
// ...
break;
}
}
I think that's right :)

Two things:
1. Anytime you put anything into a dB then use
mysql_real_escape_string() function. If you are NOT going to put it
in a dB, then you don't need mysql_real_escape_string() function --
understand?
2. Filtering is like the example I gave you before. You take
something that comes in from a POST and then compare that with what
you expect.
As with your example above -- what do you want $_POST('action) to
contain? (Please note the ERROR -- your code would never get into the
switch).
If you want $_POST('action) contain 'change' or 'edit' or whatever,
then test for that in the switch. It's the same as the example I gave
you. At some point here, you're going to have to start thinking about
what you're doing.

[PHP] 5.1.4, mysqli, and fastcgi leaving connections open.
When using PHP 5.1.4 under FastCGI and using mysqli, we are seeing that the connections do not close (filling up the max_connections limit for MySQL 5.0). In fact, the number of connections to mysql quickly become GREATER than the number of FastCGI processes. Restarting apache (and thus fastcgi) takes them out. Has anyone else noticed this? I can't imagine anyone with this configuration not noticing this. Another server with 5.1.2 is fine. Considering this knocks out all webservers connecting to the database, I think this is a critical bug in PHP 5.1.4. I'd like to know if anyone else has this issue or not before I spend a couple hours reverifying it.

[PHP] streamlining php.ini; php.ini is not parsable with parse_ini_file
All,
I want to clean up my PHP.ini file on production to be as streamlined as
possible so that it's easier to work with and maintain. It is easier to
do a diff of my INI and the recommended INI if both files are very
similar with whitespace removed, comments cleaned out, and keys sorted,
etc. I've tried to use parse_ini_file() function to parse the INI file,
but that won't work because the 'extension = *' key is used multiple
times in the php.ini. parse_ini_file assumes unique assoc array is
returned.
I'm guessing PHP doesn't actually use the parse_ini_file to read its own
ini.
So, I then started parsing the ini myself with my own custom code and
soon realized that PHP might not be using the [section] tags either as
it uses the INI key=values. Seems like the [section] tags are used more
like suggestions for key grouping than for anything functional. Is this
a correct assumption? If so, I've got the following INI reading code
which will munch the php.ini-recommended and output just the strings
which are not commented out.
See here and let me know if this looks like robust code:
//--
#!/usr/bin/php
?php
// we pass the name of an INI file on the command line
$script = array_shift($argv);
$ini_file_name = array_shift($argv);
if (!$ini_file_name || !file_exists($ini_file_name)) {
die(usage: $script php.ini file\n);
}
// slurp in the whole ini file and init
$lines = file($ini_file_name);
$data = array();
foreach ($lines as $line) {
// remove trailing comments, newlines, and start/end whitespace
$line = trim(preg_replace(/;[^\\']*$/, , trim($line)));
// skip blank lines, commented lines, ini sections, or anything
without an '=' in the line
if (!$line || $line{0} === ';' || $line{0} === '[' || strpos($line,
'=') 1) {
continue;
}
// fix spacing between equal sign
list ($key, $value) = preg_split(/\s*=\s*/, $line, 2);
$line = $key = $value;
// save this key=value pair
array_push($data, $line);
}
// sort and print all keys
sort($data);
print join(\n, $data);
?

Using mysql_real_escape_string or your db's equivalent means it becomes only one query (which won't return any results, but stops your data from being destroyed). Multiple statements means running multiple queries within the same function call: so mysql_query(select * from members where email='anything'; DROP TABLE x; SELECT 'a' = 'a';); is actually 3 sql statements (select, drop table, select), but only one call to mysql_query.

Re: [PHP] str_replace(), and correctly positioned HTML tags
Tedd, Adam, Thank you for your advice. While I'm very grateful for your advice, unfortunately, it seems that the core of what you suggest do not fit my situation. First, with Adam's suggestion that I use br / instead of p. The output I am generating is akin to what csszengarden.com generates, so that I can have complete CSS control over page layout and style. br / tags are limited in their scope of design control as compared to p tags, so they are insufficient. Second, with Tedd's advice that I place the variable without formatting within the HTML code. I apologize if I was unclear, as I seem to have given you the wrong impression. I am absolutely trying to separate content from design, which is why everything the user stores is in plain text, and all the formatting happens when it is displayed. None of the modifications which add HTML to the variable get put back into the database. The only small formatting consideration that does get stored in the database are the simulated tags (eg: --++ for h3). I'm not totally thrilled about letting users create some formatting with simulated tags, but the trade off is for giving the users more flexibility. I'm following the same model as WikiMedia, SMF Forums, and other PHP based user input interfaces. And I am trying to be more strict and less expansive than they are. I really am grateful for your advice, but it seems that I really do need to find a way to create p tags around the text when it is displayed. But I definitely thank you for giving me something to think about, and also the tips on how to make my code more efficient. It's my hope that someone can still steer me towards the ability to get p tags surrounding paragraphs, and to be able to separate h3 and other tags from within those p tags. -- Dave M G -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Mark Sargent wrote: Hi All, I get the error for line 15 for this code, ?php 15 echo font face='$_SESSION['font']'; 16 echo size='$_SESSION['size']'; 17 echo color='$_SESSION['colour']'; 18 echo $_SESSION['text']; 19 echo /font; 20 ? I have put ' ' quotes around the quotes for each font attribute so that the parser doesn't think the echo is finished too early. Is that wrong? I know that this code would get tedious for lots of text and CSS would be better, but, it's just a little study project from the book I'm following. Cheers. Mark Sargent. Hi All, sorry, I forgot the fundamentals again, . variableName . echo font face=' . $_SESSION['font'] . '; and no around the variable in an echo statement when no other text in it. echo $_SESSION['text']; Cheers.
