yup :)
And I'm even very thakful that you're helping me, to me improve my
knowledge :)
Ok, my Function looks now like this:
function mycompare ($a, $b)
{
preg_match("/([^-]*)-([^.]*)\.jpg/i",$a,$rega);//extract date and filename
preg_match("/([^-]*)-([^.]*)\.jpg/i",$b,$regb);//extract date and filename
if($rega[2]==$regb[2]) //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;
}
}
But I get a srange order like:
p1010002-05-09-12.jpg
p1010003-05-09-12.jpg
p1010004-05-09-12.jpg
p1010005-05-09-12.jpg
p1010006-05-09-12.jpg
p1010007-05-09-12.jpg
p1010008-05-09-12.jpg
p1010009-05-09-12.jpg
p1010012-05-09-12.jpg
p1010016-05-09-12.jpg
p1010021-05-09-12.jpg
p1010027-05-09-03.jpg
p1010024-05-09-12.jpg
p1010002-05-09-04.jpg
p1010025-05-09-12.jpg
p1010028-05-09-07,08,09.jpg
p1010028-05-09-12.jpg
p1010023-05-09-04.jpg
p1010029-05-09-12.jpg
p1010048-05-09-07,08,09.jpg
p1010014-05-09-05,06.jpg
to be continued...
why are there some unsorted Values between?
and why doesn't it start with 05-09-03?
is 0>1??? how to change.
Thank you!
