I think everything was a stupid mistake :P

I thought I could change the original description, but it added a
description instead. Well, all I wanted to change was "code" to
"string".

This string:
<box bgcolor="#C6C6C6" bordercolor="#000000" top="1800"
left="10"
width="100" height="30" padding="5" borderwidth="1">

Won't match this RegExp in eregi():
<BOX
bgcolor="(aqua|black|blue|fuchsia|gray|green|lime|maroon|navy|olive|purp
le|red|silver|teal|white|yellow|#[0-9a-f]{6})"
bordercolor="(aqua|black|blue|fuchsia|gray|green|lime|maroon|navy|olive|
purple|red|silver|teal|white|yellow|#[0-9a-f]{6})" top="([0-9]{1,3})"
left="([0-9]{1,3})" width="([0-9]{1,3})" height="([0-9]{1,3})"
padding="([0-9]{1})" borderwidth="([0-9]{1})">

It worked fine in PHP 4.2.x, but now in PHP 4.3.1 it doesn't.

An interesting notice might be that the string mentioned above will
match
this RegExp in eregi():
<BOX
bgcolor="(aqua|black|blue|fuchsia|gray|green|lime|maroon|navy|olive|purp
le|red|silver|teal|white|yellow|#[0-9a-f]{6})"
bordercolor="(aqua|black|blue|fuchsia|gray|green|lime|maroon|navy|olive|
purple|red|silver|teal|white|yellow|#[0-9a-f]{6})" top="([0-9]{1,3})

Code example:
<?
if(eregi('<BOX
bgcolor="(aqua|black|blue|fuchsia|gray|green|lime|maroon|navy|olive|purp
le|red|silver|teal|white|yellow|#[0-9a-f]{6})"
bordercolor="(aqua|black|blue|fuchsia|gray|green|lime|maroon|navy|olive|
purple|red|silver|teal|white|yellow|#[0-9a-f]{6})" top="([0-9]{1,3})"
left="([0-9]{1,3})" width="([0-9]{1,3})" height="([0-9]{1,3})"
padding="([0-9]{1})" borderwidth="([0-9]{1})">',
'<box bgcolor="#C6C6C6" bordercolor="#000000" top="1800"
left="10"
width="100" height="30" padding="5"
borderwidth="1">'))
{
echo "Match";
}
else
{
echo "No match";
}
?>
