Re-Running the same script if an argument is true

Tizza

Hi all

I am trying to get my script to re-run if a particular criteria is met. What i want to happen is i want my script to execute but if the preg_match of a variable is true (it returns 1) i want it to re-run the script.

script name: bsecond.php

<?php
................
$mzt = preg_match('/Never/is',$datatwo);

IF ($mzt = 1){
exec("c:\php\cli\php.exe -f c:\scripts\created\bsecond.php\");
}
?>
so basically if the word Never is present in the variable $datatwo then re-run the script

If i comment out the exec statement, and manually execute the script again, it works fine. But if i uncomment it, and run hte script, i am getting an unexpected $end at the very last line (?>).

Not too sure whats happening... any idaes?

thx!

Why are you escaping that last quote in your exec() call?

I removed that "/" you mentioned but it doesnt seem to be executing that line...even though hte criteria is met.

I think i will have to break up the script into sections and try and troubleshoot a simpler script

thx

Oh yes... I have an idea.... and missed it the first time.

IF ($mzt == 1){
    exec("c:\php\cli\php.exe -f c:\scripts\created\bsecond.php");
}

= will set a variable to a value.
== will compare the items to whether they're equal to each-other or not.

So there seemed to be two issues:
1.) You were using "=" instead of "==" to check equality
2.) You escaped the ending '"' which would have failed your PHP script in executing.

thanks for the help!! that part works.... but when the original script executes it doesnt re-run the script... i have to manually go in and run it.

Try echoing the output of the [man]exec/man function.

Ech, imagine how many instances of PHP could end up running, all but one of them sitting idle while they wait for the last one to complete. That's the sort of approach I'd use in an Obfuscated PHP programming contest. (Wait a minute, I did.)

do
{
//...
} while (preg_match('/Never/is', $datatwo));

Assuming that the stuff in ... does have to run at least once.
