Blonde moment

[meghatronic]

... I'm having one... partly as str_replace as no offset vars.

I have a string such as the following:

absfasdfasf--------------sf3ssafasf--------4asdfsdfasdfasdfasf.......

I want the position of the '3' (strpos) BUT, with all the hyphens before it removed:

absfasdfasfsf3ssafasf--------4asdfsdfasdfasdfasf.......

Likewise, for 4:

absfasdfasfsf3ssafasf4asdfsdfasdfasdfasf.......

I'm stuck

substr()?

substr()?

I can't see how

As in plug the figure (gained from using strpos() to locate 3's position) into substr(), I would guess.

But I need the position of the 3, not 3 itself using substr.

I think, I can just use str_replace as any - to the right of 3 are irrelevant to strpos.

Not sure.

Ah, I think I almost understand what you're doing - I thought you wanted the section of the string after strpos value, rather than the strpos() value itself.

Yes, can you not just strip all the hyphens, and then run strpos() on the resulting string?

$string = str_replace('-', '', $string);
$needle = '3';
$pos = strpos($string, $needle);

<?php

$needle = '3';
$str = 'absfasdfasf--------------sf3ssafasf--------4asdfsdfasdfasdfasf.......';
$pos = strpos($str, $needle);

$prstr = str_replace('-', '', substr($str, 0, $pos));
$newstr = $prstr . substr($str, $pos);

?>

Like that? Slightly confuzzled logic (get position, split string, remove hyphens from first half, concatenate second half) but it gets the desired results.

It would be a hell of a lot easier if you just posted your end goal, instead of making multiple (now several) threads about manipulating the same string.
