[RESOLVED] split not working?

[OniLink]

This code doesn't out anything:

$r1 = '4.4.4.4.4.4.4.4';
$tips = split('.', $r1);
echo $tips[0];

It should echo '4', but it doesn't!? I've never encoutered a problem with split() like this.

That is pretty funky. My off-the-top-of-my-head guess is that php split() converts the string to a number perhaps????

anyways...

$tips = preg_split("/\./", $r1);

works as expected.

Well, as split is a regular expression function, I'd think you need to escape the dot or your pattern would be quite meaningless, possibly leading to unexpected results. But anyway you don't need regular expressions here at all, so I'd highly recommend

$tips = explode('.', $r1);

Also you could use explode() which will work(and its faster than preg_split)

If for some reason you feel a need to use split(), since "." is an ereg wildcard, you'd need to use of of these:

$tips = split('[.]', $r1);
// ...or...
$tips = split('\.', $r1);

However, I'd opt for the explode() solution, myself, since there's no need for a regex in this case.

Perfect! Thanks again guys. I swear I tested explode o_O
