Extract substring

[nigeledge]

Which function would I use for extracting text or characters between two strings?

For example...

If I have this string:

$some_string= "start 39dkskasdi39r0shf908 n3lnelnsfnose34509js fsneflsnfsfnsfsdfn4r9nfe90sf stop";

How can I extract the text between start and stop?.. so I end up with this...

$new_string = "39dkskasdi39r0shf908 n3lnelnsfnose34509js fsneflsnfsfnsfsdfn4r9nfe90sf";

I cannot use substr() since the length of the original string will vary from page to page.
Thanks in advance.

you can use substr() + strlen()
hope that helps

Would this do the trick?

$some_string=preg_replace("(start | stop)","",$some_string);
