creating and changing parts of the created php file - php

Question

I wonder what ist he best way to do the following.
I am creating a webseite CMS. Through CMS I am creating new folders with index.php files in them. For example I have created folder with the site new_folder_name/index.php
I wonder what ist the best way to make an interaction between the created index.php files and database. For example I am creating the php file with another php file
<?php
$dir = "../new_folder_name";
$file_to_write = "index.php";
$content_to_write = '
<?php
//// php code
$foo=‘3‘:
?>
if( is_dir($dir) === false )
{
mkdir($dir);
}
$file = fopen($dir . '/' . $file_to_write,"w");
fwrite($file, $content_to_write);
fclose($file);
include $dir . '/' . $file_to_write;
?>
I am putting a variable $foo that needs to be changed with every new php file created. I could create $foo=GET(´SOEMTHING´) but this GET is making problems since this variable needs to be changed, and only for this file a unique value. I do not know if I explained it properly but I hope I did. In which way can I create a php file with specific $foo value or change the created file with php in order to get the $foo value which I want.

Answer 1

you can do
$content_to_write = '
<?php
//// php code
$foo=\'$_GET[\'something\']\';
?>';
this is make your new script to read $_GET['something']
OR
this example, read this script's $_GET['something'] and put it's value in script...
$content_to_write = '
<?php
//// php code
$foo=\''.$_GET['something'].'\';
?>';
since you use single quote $_GET didn't get parse with original script. If you want to use that simply concatenate it. Alternatively you can concatinate '$' in between string to make variable just variables.
