[SOLVED] PHP config editor

[opencombatclan]

Hello everyone.

I am currently working on a little project.

Now I tried to make a php config editor, but without success.

I simply can not get it to work...

 

This Is what i want to do.

I have a file, named file.php

<?php
//Some
//comments
$flower = "red";
$case = "black";
$done = "0";
//end of config file
?>

 

Now I need a function which does the following:

1.) Open the specific file (file.php)

2.) Search for the var $flower

3.) Change its value to "green"

 

So the file will look like:

<?php
//Some
//comments
$flower = "green";
$case = "black";
$done = "0";
//end of config file
?>

 

I tried it with fopen(), fread() and fclose(), but since the function does not know what is the value of $flower at the beginning, I did not get it to work.

Can someone help me out?

The function you are looking for would be SED which is a Search and Replace editor for Linux.

 

I found a good article online which may assist you in using the functionality within PHP

Are you looking for a form which will edit the config variables?. Like an installation file?. If yes use $_POST

No I am looking for what i described in my first post

 

Now I need a function which does the following:

1.) Open the specific file (file.php)

2.) Search for the var $flower

3.) Change its value to "green"

 

(Please also see my examples for some further explanation)

I fixed it using:

 

<?php
function set_var($file,$var,$val)
{
$array = file("$file",FILE_IGNORE_NEW_LINES); 
$lines = count($array); 
for($i=1; $i<$lines-1; $i=$i+1) 
{
$line = $array[$i];
	if ($line[0] == "$") 
	{
                list($var_tmp, $val_tmp) = explode("=", $line);
	$variabele = substr($var_tmp, 1, -1);  
                  	if ($var == $variabele) { $array[$i] = "$var_tmp= \"$val\";"; }
	}
}
$fh = fopen($file, 'w') or die("Could not update config.php");
$stringData = "<?php\n";
fwrite($fh, $stringData);
$lines = count($array);
for($i=1; $i<$lines-1; $i=$i+1) 
{
$line = $array[$i];
fwrite($fh,"$line\n");
}
$stringData = "?>";
fwrite($fh, $stringData);
fclose($fh);
}
?>

 

This will do exactly what I asked in my first post.

But its a huge pile of code, and I am sure it can be done way faster.

Can anyone give some suggestions on how to optimize this code?
