how could I take a string and push each character into an array?

explode?

But you need to use a separator for that, so how could I just take every single character and push it into an array.

Ok buddy, JUST as easy lol.

function make_string_array($string)
{
$mychrs = array();
$strlen = strlen($string);
for ($i = 0; $i < $strlen; $i++)
{
$mychrs[$i] = substr($string, $i, 1);
}
return $mychars;
}
$somechrs = make_string_array('hello');

THERE.

I didn't test it so you might get some errors.

[DFox]

Augh I can't fregin test it because the filemanager in Plesk decided not to work. How convenient.

I wrote it quickly, so again, let me know.

[JeremysFilms]

Works, except that sometimes you used $mychars and sometimes you used $mychrs. But here's the fixed version:

function make_string_array($string)
{
$mychars = array();
$strlen = strlen($string);
for ($i = 0; $i < $strlen; $i++)
{
$mychars[$i] = substr($string, $i, 1);
}
return $mychars;
}

Yeah, I just noticed that. Glad it works now.

You can just use explode() and use a blank separator and it will split the string into characters and store them in the returned array.

That's exactly what I thought at first :) Then I looked at the documentation and it said you can't have a blank separator (nor does it work when you test it). That's why I wrote that function.

Was thinking the same exact thing, also another method but I forget the exact function.

isn't there a push function in PHP?

yep:

That doesn't really have anything to do with actually taking the characters from a predefined string.

I swear to all that is holy that that method used to work. Maybe they modified it in PHP5? I don't know, but I could have sworn I had used it before. Anyway, PHP stores strings as optional NULL-terminated arrays anyway, so you can access the characters like that.

Ha, that's weird. I used to be running PHP 4 on my server but I'm running PHP 5 now so I can't test it. It very well could have been changed.

That's very interesting with the string array, as that's a nice easy way of doing it. I didn't know about that method.
