Quick PHP Question

[l6873]

Let's say I have a variable like this:

$string = 'START this is some random text END';

How would I go about extracting everything between the words 'START' and 'END'? I could just look through the manual but someone probably knows...

Do you know how regular expressions work?

http://us2.php.net/manual/en/ref.regex.php

Or you could do it ghettoly and use two calls to the split function (using "START" and "END" as your delimiters)

Maybe more specific... are you trying to just find the information between the first and last word of the variable?

Maybe we could think of a better solution if you tell us what it is for.

substr($sting, 4, strlen($string)-8);

I think.

No, there might be some other text before START and after 'END'.

The two suggestions I gave you would work in that case. If you don't want to learn about regular expressions, use SPLIT. Or use strpos and substr.

I've used regular expressions in the past. Doesn't split use regular expressions as well?

here's a simple way

if your string contains more than one start and end points you'll have to do a lot of legwork though.
