conditional preg match

[toedipper]

Hello,

The following bit of code does a preg match and does something if true
(sets $browser to ppcie)

Without using if then and else's how do I code it so it does not equal
what it is testing for? So if it does not find ppc in the $agent then
it does something else/sets it to something else?

$agent = getenv("HTTP_US ER_AGENT");
if (preg_match("/PPC/i", "$agent")) {
$browser = 'PPCIE';
}

Thanks,

What on earth's wrong with if/else?

But alternatively:

$browser = (preg_match(... )) ? 'PPCIE' : 'something else';

Hello!

preg_match("/PPC/i", "$agent")

^ ^

IMO you should use >$agent< instead of >"$agent"<.
Furthermore you are only doing a check whether one string is in another.
Use stripos (PHP5), strpos in combinanation with strtolower or stristr
for this.
IIRC the second is the fastest for PHP4.

if (strpos(strtolo wer($agent), 'ppc') !== false) {
// ...
}

http://php.net/strpos
http://php.net/stripos
http://php.net/strstr
http://php.net/stristr
http://php.net/strtolower
