what do you mean with 'match all function'
Ok, I've tried it like below, but doesn't really work,
$rega[1] is always ""
and in $rega[0] is the whole filename... :(
[Code]
function mycompare ($a, $b)
{
$rega=split("/([^-]*)-([^.]*)\.jpg/i",$a);//extract date and filename
$regb=split("/([^-]*)-([^.]*)\.jpg/i",$b);//extract date and filename
echo $rega[0]." [0]<br>\n";
echo $rega[1]." [1]<br>\n";
if($rega[1]==$regb[1]) //compare date
{
//first check for search text in $a and $b
$isInA=(strpos($a,'p')!==false);
$isInB=(strpos($b,'p')!==false);
//so if $isInA==$isInB then compare alphabetical
//but reverse first a & b
$a=strrev($a);
$b=strrev($b);
if ($isInA == $isInB)
{
if ($a == $b)
return 0;
return ($a > $b) ? 1 : -1;
}
else
{
//the one that is true comes first
return ($isInA) ? -1:1;
}
return 0;
}
else
{
return 0;
}
}
[/Code]
Sorry, but I'm quite new to that stuff.
