Bug description: eregi() crashes or runs terrible slow
I have an own e-mail source parser script for an archive engine. It has been working
for a long time without errors, but it was crashed yesterday.
I have found the problem: eregi() halts with a 13k long text. This is same with PHP
4.0.3 Windows and PHP 4.0.4pl Debian Linux.
I include a short script to show it:
--------
<?php
$cuts = array("_______________________________________________\n");
$lines = file('\work\mail.txt');
foreach ($lines as $l) {
$text .= $l . "\n";
}
$text = str_replace(chr(13),'',$text);
echo strlen($text) . "\n\n";
foreach ($cuts as $c) {
$ok = true;
$cnt = 0;
while ($ok && $cnt < 15) {
echo $c . "\n";
$regs[2] = '';
eregi("(.*)($c)(.*)",$text,$regs);
$text = $regs[1] . $regs[3];
$ok = ($regs[2] == $c) && ($c != ''); // originally it was "$ok = $regs[2]", but
I was trying to find the problem so I have changed
$cnt++;
echo strlen($text) . "\n\n";
}
}
?>

This is the result with windows/php4.0.3:
