OK, thanks for that. I've rewritten your function below in much cleaner
code. Some of the situations you've used regexps in, string functions
would work fine. They're also much faster.
The below function works fine in my testing. I removed the special-case
for a valid MAC address at the start since your regexp was throwing
errors and there was no need since you already checked if it was valid
with chk_mac() (which by the way should return true or false, not 1 or
0, but meh).
<?php
function fix_mac( $mac ) {
if( eregi(
"^[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}\-" .
"[0-9A-Fa-f]{2}$",
$mac
) ) {
$mac_final = str_replace( '-', ':', $mac );
} else if( eregi( "^[0-9A-Fa-f]{12}$", $mac ) ) {
$mac_array = str_split( $mac, 2 );
$mac_final = implode( ':', $mac_array );
} else {
return false;
}
echo "MAC: $mac_final";
return $mac_final;
}
?>
