How to replace a certain text in file with php

BloodHound

Hello, for example i have a settings.php file, the contents is

<?
$params["debug"] = true;
$params["title"] = "test";
$params["timeout"] = 1000;
?>

and a html form used to change the settings:

<html>

<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Server Settings</title>
</head>

<body>
<div class="flo2">
<div class="lc"><div class="commonbox"><div id="settings" class="commonbox sn_greenbor">
<div class="login">Server Settings</div>
<div class="boxcontent"><form name="server_settings" method="post" action="set.php">
<table cellpadding="3" cellspacing="0" border="0">
<tr><td colspan="2"></td></tr>
<tr>
<td style="text-align:right !important;"><strong>Title:</strong></td>
<td><input type="text" name="title" maxlength="100" size="22" alt="title" tabindex="1" style="width: 200px !important;" value=""></td>
</tr>
<tr>
<td style="text-align:right !important;"><strong>Timeout:</strong></td>
<td><input type="text" name="timeout" maxlength="10" size="22" alt="timeout" tabindex="2" style="width: 200px !important;"></td>
</tr>
<tr>
<td><strong>Debug Mode:</strong></td>
<td>
<input type="checkbox" name="debug" id="debug">
</td>
</tr>
<tr>
<td></td>
</tr>
<tr>
<td></td>
<td valign="bottom"><div class="SetButton clearFix">
<div class="floatL"><input type="submit" name="btnSet" value="Change Settings" tabindex="3"></div>
</div></td>
</tr>
</table>

</body>

</html>

How to connect the form to php, what is the contents of the set.php? (php file to be executed after I press Change Settings)
something like search the word true in $params["debug"] = true; and replace it to false according to the html form (if the checkbox is checked or not)
and how to read the existing value in the settings.php and display it in the form.
something like if the settings.php have a $params["debug"] = true, so the checkbox in the form is checked

thanks and sorry for my bad english
I hope you're not confused..

Instead of trying to change the assignment of variables in a PHP script from another PHP script, you may wish to use a relational database, in which case you would just use an SQL statement to update the database.

If you are not familiar with databases, a simpler solution would be to use an ini file, which could be read into your array with [man]parse_ini_file/man. A dumb but workable method of changing the settings would then just be to read the ini file, change the elements of the array, then write the array to the ini file in the ini format.

erm.. unfortunately the settings is integrated into index.php 🙁 ..

any other way?
something like JSON or YAML, so I can parse the settings into an array/variable.

thanks

That doesnt make sense 🙂 You dont have to change index at all. If the settings.php is included in index, you can leave it like that. You would only edit the new ini file and settings.php would be just this:

<?php
$params = parse_ini_file('settings.ini');

And settings.ini would be like this:

debug = true
title = "test"
timeout = 1000
