PREG_REPLACE on a token with '$'

[sshrum]

Long time...re-working a script I wrote about 5 years ago.

 

I'm trying to nest but my token word is "$nest$" and this just isn't working:

 

$sPage = preg_replace ('$nest$', $aTemplates['body'], $aTemplates['page']);

 

It is leaving the "$" in the page and just replacing "nest".

 

TIA

use explode function to first explode all the $nest$ into an arrays of strings

The $ are acting as delimiters, which you haven't used.

I've looked over the links and still haven't figured out the correct syntax.

 

What is the PREG expression for replacing "$nest$" in a string?

preg_quote...nvrmnd

str_replace works just the same...I've found out.

I think this is what you want?

 

<?php

$str = 'A $nest$ here and a $nest$ there.';

echo 'Replace strictly $nest$: ' . preg_replace('/\$nest\$/', '$new$', $str) . "\n";
echo 'Replace all within $\'s: ' . preg_replace('/\$([^\$]*)\$/', '$new$', $str) . "\n";

/*
* Output of above code:
* 
* Replace strictly $nest$: A $new$ here and a $new$ there.
* Replace all within $'s: A $new$ here and a $new$ there.
*/

?>

If both do the same then use str_replace instead of preg_replace. The former is considered much faster.

But, if the text inside the $'s differ, it wouldn't be a realistic solution.
