php string separation

[electricphp]

If I have a $_post variable that holds the value "red - 45"

and I would like to load that into two different variables:

$color and $price, how would I go about it?

 

[Foamcow]

try

$a = explode(' - ',$_POST['string']);

This will give you an array containing your values

$a[0] = red
$a[1] = 45

You can also use

list($color, $price)=split(" - ", $_POST['varname']);

echo $color = red
echo $price = 45

Good luck!

just for interest split is not a synonym for explode, although they have similar results. split engages the regular expression engine in php, which is inefficient (it's looking better in php 6). explode does not, and for simple tasks, should be favoured.

the manual also favours preg_split() over split.

Tip
preg_split(), which uses a Perl-compatible regular expression syntax, is often a faster alternative to split(). If you don't require the power of regular expressions, it is faster to use explode()

Can I pretend that I knew that?
