Matching specific amounts of space and tab characters

[Prismatic]

What I'm working on is complicated but my problem isn't.

 

I'm trying to convert sets of tabs and spaces into other characters.

 

For example, say I have the following.

One tab
	Two tabs
		Three tabs

 

What I'm trying to do is end up with the following

[hl=/t][/hl]One tab
[hl=/t/t][/hl]Two tabs
[hl=/t/t/t][/hl]Three tabs

 

Note the three /t's for the three tabs. My issue is when the script generates the regex to do the first line there, which has one tab, the regex is

/[\t]{1}/

 

But that converts all the tabs. It's hard to explain ugh.

 

All I can manage is

[hl=/t][/hl]One tab
[hl=/t/[/hl][hl=/t][/hl]Two tabs
[hl=/t/][/hl][hl=/t][/hl][hl=/t][/hl]Three tabs

 

 

help?

<?php

function tab_replace($args) {
    $tmp = '[h1='.str_replace("\t",'/t', $args[0]).'][/h1]';
    return $tmp;
}

$text = '
One tab
	Two tabs
		Three tabs
';

$output = preg_replace_callback('/\t+/', 'tab_replace', $text);
echo $output;

<?php

function tab_replace($args) {
    $tmp = '[h1='.str_replace("\t",'/t', $args[0]).'][/h1]';
    return $tmp;
}

$text = '
One tab
	Two tabs
		Three tabs
';

$output = preg_replace_callback('/\t+/', 'tab_replace', $text);
echo $output;

 

That works great thank you

 

[h1=/t][/h1]This text is inside the pre element, it will be parsed.
[h1=/t][/h1]Tabbed text
[h1=/s/s][/h1]Two spaces
[h1=/s/s/s][/h1]Three spaces
[h1=/s/s/s/s][/h1]four spaces[h1=/t][/h1]and a tab
[h1=/t/t][/h1]Two tabs

 

Adapted it for spaces 2+

 

$output = preg_replace_callback("/[ ]{2,}/", "space_replace" , $output);

...

function space_replace($args)
{
	$tmp = '[h1='.str_replace(" ",'/s', $args[0]).'][/h1]';
    return $tmp;
}

 

 

Cheers!

 

 

Edit - where's the solved button at?
