Operating system: Linux php3-2 2.4.7 #1 Thu Aug 9
PHP version: 4.0.6
PHP Bug Type: Strings related
Bug description: str_replace unable to match search string
Summary :
A function works well on php 4.0.5 and enters an infinite loop on php
4.0.6.
Function entering in infinite loop :
The purpose of this function is to parse a template containing some tags,
line by line, and replace them by values contained in the $t_strings
array.
The input can be :
<td bgcolor="#FFCC00" colspan="2"><phpdig:previous_link
src='./tpl_img/left.gif'/><phpdig:pages_bar/><phpdig:next_link
src='./tpl_img/right.gif'/></td>
i think the str_replace() function don't replace anything ; the while
statment stays always true, etc...
function parse_phpdig_tags($line,$t_strings)
{
while(eregi('<phpdig:([a-z0-9_]*)[[:blank:]]*(src=)*["\']*([a-z0-9./_-]+)*["\']*[[:blank:]]*/>',$line,$regs))
{
//links with images
if ($regs[2])
{
if ($regs[3] && $t_strings[$regs[1]])
{
if (ereg('^http',$t_strings[$regs[1]]))
$target = ' target="_blank"';
else
$target = '';
$replacement = '<A
href="'.$t_strings[$regs[1]].'"'.$target.'><img src="'.$regs[3].'"
border="0" align="bottom"></a>';
}
else
{
$replacement = '';
}
$line = str_replace($regs[0],$replacement,$line);
}
else
{
$line =
str_replace($regs[0],$t_strings[$regs[1]],$line);
}
}
return $line;
}
