hex character codes

[Anon]

When doing a substr_count or an explode, or anything where you need to specify a 'needle' string, Is it possible to use a hex character code instead of writing in the character? ie '20' instead of ' ' (space)? If so, how?

you can try this:

1. convert your hex ascii to dec ascii with hexdec. ie hexdec(20) will give you 32
2. use chr() to convert that decimal ascii to the char you want. ie chr(32) will return a space.
3. put that in your explode call for your needle ie:

explode(chr(hexdec(20)), "this is exploded by spaces");

that ought to do the trick.
