Replace A Line In Text File

[dakke]

Hi,How can I replace a line in a php file, where e.g. I find $db_connection?So, say that on line 4 I have:

$db_connection = 'justanexample';

or even

$db_connection = 'justanotherexample';

Is there a way to search for $db_connection and replace the entire line with say

$db_connection = 'replaced line';

?Thanks

Cant you just redeclare the $db_connection variable when php reads the file as a php file? I mean when you do something like:include("Database.php");Database.php

<?php$db_connection = "database1";?>

index.php

<?phpinclude("Database.php");if(isset($db_connection) || $domain == "text.nl")){  $db_connection = "database2";}else{  echo 'Database is set to the default';}?>

If you want to replace the part between quotes you need to use a regular expression with preg_replace. You could also use strpos to search for the beginning of the line and then the position of the next newline and replace the entire line with your own, or you could split the lines up into an array and loop through checking for the one you're looking for.
