Searching and replacing with Variables

[Daleeburg]

Is there a way in php to make it search and replace with variables, so like if i had this

 

whatever="[text]-[number]"

 

in a page full of code and i just wanted to change the number portion of it well leaving the text alone?

str_replace will help you

[Daleeburg]

The problem is that i dont always know the number, so i need to find a way to retrieve it.

[Lumio]

you mean that there is a part with text like

 

whatever="foo-123"

? And you wnat to get to know what the number of the text is?

[Daleeburg]

exactly and then change the number to a preset number

Take a look at preg_replace. if you get stuck with the regex ask your question in the regex board.

<?php

/* Method 1 - This method replaces ALL numbers with $replacement */

$replacement = 1;
$string = "hello-123";

echo preg_replace("/(\d+)/", $replacement, $string);

/* Method 2 - This method just replaces with the syntax [string]-[number] */

$replacement = 1;
$string = "hello-123";

$pieces = explode("-", $string);
$pieces[1] = $replacement;

echo join("-", $pieces);

?>
