strstr function

[jeff21]

I'm trying to use the strstr function to find IP ranges and block them.

For some reason, I cannot get the strstr function to recognize the string. I have the following code

$bad_ip = "12.235.234.180";
$result = strstr($bad_ip, '12.' or '61' or '203' or '210' or '211' or '218' or '219');
print $result;

This code does not print anything for $results

Thanks

Jeff

strstr() can't take multiple keyword arguments like that. You would have to test for each one individually. If you have a list of ip's that you don't allow then i suggest you store them in an array and then use in_array() to validate

Thanks for your reply...I'm not sure if in_array() would work well for IP blocks though.. ie/ 216.xxxxxxx, 52.xxxxxxxx
