changing text with php

[x_maras]

Hi,

 

is it possible to change a word of a text or some part of it with php?

 

for example if I ve got this file temp.txt and in the text there is a word "change" can I change it with this: $text="something"  ?

 

I think I would be possible with regexps, I looked but I don't know where exactly to look.

If you could give me an example or link me somewhere would be very helpfull.

 

Thanks

str_replace

 

$file = file_get_contents('temp.txt');
$replace = 'change';
$with = 'changed';
$new = str_replace($replace,$with,$file);
echo $new;
