Trying to use error_get_last - jLinux - 07-16-2015
In a portion of my script, I try to validate a regex pattern provided by a user, not testing it against a string, but just executing it arbitrarily, then checking for PHP errors. I tested it in a stand alone script and it works perfectly fine, however when I throw the code into a CI library method, it doesnt work at all. I googled it and I found some people saying they had error_get_last() working fine in CI, until they upgraded to a recent version.
Is error_get_last disabled for some reason? is there another way to accomplish the exact same thing?
Heres the stand alone script I was talking about:
PHP Code:
<?php
$pattern = '/890(*D)(F*asdf/asdf98SDF$#%@#$';
$str = '';
$regex = @preg_match($pattern, $str);
$error = error_get_last();
if(isset($error['message']))
echo "Regex Error: {$error['message']}" . PHP_EOL;
elseif($regex)
echo "Matched" . PHP_EOL;
else
echo "No Match" . PHP_EOL;
Again, that works perfectly fine, until thrown into CI
Thanks!

As mentioned in the manual notes for error_get_last(), there are many reasons that it may not work, including the error handler set by CodeIgniter returning a non-FALSE value. Since I haven't tested this, I don't know if that's a strict check; CI has a void return from the error handler if the severity of the error doesn't meet the error reporting level. CI 2 returned from the error handler under slightly different circumstances, and the error reporting levels changed slightly between versions, too.
The manual notes contain a number of potential work-arounds, too. In this case, though, I wonder if preg_last_error() has the same issues, or if it just wouldn't work for your situation.

Good idea, I just gave it a shot tho..
Code:
PHP Code:
$pattern = '/asdf/df/asdf/adsf';
$str = '';
$preg_errs = array(
PREG_NO_ERROR => 'No Error',
PREG_INTERNAL_ERROR => 'Internal Error',
PREG_BACKTRACK_LIMIT_ERROR => 'Backgrack Limit Error',
PREG_RECURSION_LIMIT_ERROR => 'Recursion Limit Error',
PREG_BAD_UTF8_ERROR => 'Bad UTF8 Error',
PREG_BAD_UTF8_OFFSET_ERROR => 'Bad UTF8 Offset Error'
);
preg_match($pattern, $str);
$err = preg_last_error();
echo "ERROR: {$preg_errs[$err]}\n";
Output:
Quote:PHP Warning: preg_match(): Unknown modifier 'd' in /Users/jhyland/PhpstormProjects/SASSET-App/htdocs/preg.php on line 14

ERROR: No Error
Odd, thats not even via CI
