Hello,

I have an old version of php (4.3.2) that is acting rather strangely. I'm
searching two large arrays (approx 22,000 records in each) using
array_diff_key() from the PEAR PHP_Compat library:

$result = $args[0];
foreach ($args[0] as $key1 => $value1) {
for ($i = 1; $i !== $array_count; $i++) {
foreach ($args[$i] as $key2 => $value2) {
if ((string) $key1 === (string) $key2) {
unset($result[$key2]);
break 2;
}
}
}
}

And I'm getting aweful performance. I know it's a ton of records (22,000 *
22,000), but it shouldn't take 16 minutes on a P4 Xeon 2.4ghz!

Has anyone seen this before? Is this a bug? Or are my math skills lacking and
this is perfectly normal performance for the size of the data set?

Thanks!
