So I send it again from anther email === No, actually, you sent it from the exact same address --- but both came through anyway. I am developing a php application that interfaces with an external executable binary. The program is written in C++. I open the program (say a.out) using proc_open. Write some command at its stdin and fetch data stdout. Then close the program. The timing of only a.out is real 490ms usr 160ms sys 290ms When I invoke it using proc_open in php-cli, the timing becomes real 530ms usr 50ms sys 450ms Look closely, the cpu time and the real elapsed time increases. I run the php version from command line. As an apache handler this will surly take more time. Is this just the processing time of the a.out file, or is this considering the PHP script's execution time including the a.out processing? If so, this increase is, of course, to be completely expected. Also, were the input and output exactly the same size in bytes as the direct test? The program a.out can not be converted in php unless I write an extension. But this will need a lot of effort to write it in PHP. Extensions aren't written in PHP, they're binary packages. Some of my ideas are, 1. Create a standalone multi-threaded server that calls a.out and php calls that server. This is the same basic idea that Facebook's HipHop project uses. 2. Call a.out as a CGI and convert it that way. This would likely be your best bet, as you're stripping away all of the excess interfacing by PHP (or another scripting language), and would instead just be accessing it directly via the web server. That said, it would depend on whether or not your program is (or could be) written to handle everything itself, so that PHP - or any capable language, for that matter - would no longer be necessary. -- /Daniel P.

[PHP] Re: PHPmailer.. best way to send to many recipients?
followup question, please see below the OP:
I just started using PHPmailer for one project that requires SMTP
authentication (if I said that right).. and all is well.. but I want
to ask now before it might get outta hand later:
How many comma-delim'ed addresses can I stuff in $BCC_recipients
before I have problems (need to restructure the design)?
--
require(php_inc/class.phpmailer.php);
$mail = new PHPMailer();
$BCC_recipients = x...@host.com,y...@server.com; // ---just an
example
$arrBCC_recipients = explode(,, $BCC_recipients);
foreach ($arrBCC_recipients as $email2stuffInBCC) {
$mail-AddBcc($email2stuffInBCC);
}
if(!$mail-Send()) { // problem
--
For now there will be less than 100 Bcc recipients.. but later,
more. I don't know if/when it will ever grow past 1,000.
I see from reading on a PHPmailer list that the main concern people
expressed from this (above) approach is to not go over limits set by
the host/server as to how many emails can go out before being marked
as spam. OK, understood.
Here I am just asking about the code. I mean does it make any
difference in terms of code reliability whether I loop on $mail-
Send() -versus- looping on/concatenating the Bcc addresses?

It works perfectly well and is a great solution in extremely limited cases.
The problem is that it can be used in many cases where other control flow
statements are more clear. It was more of a problem before because people
came from languages that had goto but not the other high-level control flow
statements. Using goto often leads to hard-to-follow code.
For example, rearranging the above code yields
do {
if (!acquireTarget()) {
break;
fireMainCannon();
fireMissiles();
} while (enemiesInView());
Even this doesn't get away from using break--a special form of goto for
loops. One way around that is to introduce a loop variable like $done, but I
think break is cleaner here. Sometimes goto, break, and continue are simply
the best tools for the job. I wouldn't say never use goto, but I do feel
that 99 times out of 100 you're probably better off using something else.
One thing to keep in mind is that under the hood the PHP interpreter turns
while(), for(), etc. into a bunch of gotos.
for ( init ; check ; increment ) block
is just a shorter way to write
init
goto check;
loop:
block
increment
check:
if (check)
goto loop;
The same can be done for all the other control flow statements.

Re: [PHP] PDO Prepared Statements and stripslashes
Hello, The plug-in PDO has nothing to do with the backslashes being inserted into the database. The backslashes are used to escape characters like in D's...it would show D's. That's the safe behavior of it. You can change your programming code to fix that. Ravi.

Also use var_dump($query_name) to find out what is spits out.
Debugging is your best friend here. If you don't use die() or

This code will totally eliminate the first row of data.
if (mysql_num_rows($result) == !'0') {
$row = mysql_fetch_array($result);
Fetches the first row, but is not output. Because:
while ($row = mysql_fetch_array($result)) {
Fetches the second row before you do any output of the data.
Eliminate the first fetch_array and you're code should work fine.
BTW, if you put the td attributes 'width=n' in the preceding th
tags, you won't have to output them for each row. You should also put
the
units those numbers are associated with.

The {3} part is equivalent to the array position. Change that number, and

Re: [PHP] Error Querying Database
Trying to connect to the database can involve setting up your database. Make
sure that you have a valid login/password that is recognized by MySQL.
Please keep in mind that MySQL works on permission by hosts. So your host IP
must be matched with the username/password on the database for a successful
authentication. One way to know that you can connect successfully to your
remote database is to actually test it. Download MySQL Workbench from
Mysql.com and then try to connect to remote from the same host that your php
application is sitting at. If it works, thumbs up. If it does not then you
have a permission issue there. Add your username/host appropriately.
If you can connect without a hitch then you are doing something wrong on
your code. Use mysql_connect(), mysql_select_db() and then send an statement
and use the resource to see if it returns TRUE or FALSE. At this point, on
FALSE it means that you have a bad written statement.
There is so much that can go wrong. Debug step by step.

Try echoing your query to the page by putting echo $query in your code
before you call mysql, then copy it and run it in phpmyadmin. If it runs
then you know your problem is somewhere else like the connection. This can
really help you find typos that can cause mysterious results.
If you want to use the same page to process the form (my preference) then
put a hidden field in your form like:
input type=hidden name=phpaction id=phpaction value=process /
and wrap the form processing code like so:
if (isset($_POST['phpaction'])) {
//process submitted form data
} else {
//processing for initial form entry
}
When the form is initially loaded it will ignore the first part
There are a 1000 ways to do this, but this is pretty straightforward.

This is a duplicate of a script I have used countless times and it
worked.
The error message is 'Error querying database.'
Some one point out the error of my ways?

Read Ash's reply... but basically, you're running the query with POST
variables, and inserting them on page display as well as on form submit.
can you ensure that you can connect from the command line?
if you may take some criticism, you should rethink your database design,
as well as the page flow/design... you should either post the form to a
new page, or if it is back to itself, you should check to see that you
have in fact posted it before just blindly inserting into the database
(as currently, every time you view the page, you will insert into the
database, even if completely empty values).

Thank you for your reply.

Re: [PHP] Problem with Include
My point is that you tried to take code from one page and put it all organized in another page and the include that page of includes back into the pages that you want it to feed off from. If stuff works the way that it does then there a reason for it to have been done that way. That's why documenting code is so important. 99% doesn't do it (including me). Ravi.

If you are trying to make it pretty then you are not solving a problem. You are creating one. Define working. I've had programs 'work', but more experienced would say it's flawed in some respect. Does it perform the immediate task? Now define pretty. Is it aesthetically pleasing to you, or to someone else with less, or maybe more experience. By defining the two above, you then define whether it's a problem. To you, or to them, or to the original designer? Ravi. On Mon, Dec 20, 2010 at 7:40 AM, Daniel P.
