Store php code in a variable to write to file

Hi Experts,

I am trying to write an automated setup script so that when user types in details on a form a config file is written to the server.

This is my code:

$handle = fopen($setting['config']['folder'] . $setting['config']['file'], 'w');
	

$input = "<?php
// Generated ".date('F j, Y H:i:s')."

// Database Details

$config['hostname'] = '$db_host';
$config['username'] = '$db_user';
$config['password'] = '$db_pass';
$config['database'] = '$db_name';
$config['table_prefix'] = 'sadmin_';
$config['universal_admin_url'] = '$admin_url';
$config['base_url'] = '$base_ur';
$config['seo_page'] = '$seo_page';
$config['show_errors'] = true;
$config['webmaster_email'] = '$webmaster_email';
$config['webmaster_name'] = '$webmaster_name';
$config['language'] = 'english';
?>
";

fwrite($handle, $input);
fclose($handle);
if (file_exists($setting['config']['folder'] . $setting['config']['file']))
	echo '<h3>Configuration file created!</h3><p>The file <code>'.$setting['config']['folder'] . $setting['config']['file'].'</code> has been created successfully. To continue the installation, please continue the installation. </p><a href="?step=3" class="button" style="float:right;"> <span>Generate Database Tables &rsaquo;</span> </a> ';
else
	echo '<h3>ERROR!</h3><p>Configuration file was not created. Please check the the folder <code>'.$setting['config']['folder'].'</code> is created and the permissions to the  folder are set to <code>777</code>. After checking, click the link button below to regenerate the configuration file again..</p> <a href="?step=1" class="button fail" style="float:left"> <span>&lsaquo; Regenerate Configuration</span> </a>';

Open in new window



But its not working. What I am trying to achieve is the config file shows this inside
<?php

// Generated September 6, 2011 16:00:00

// Database Details

$config['hostname'] = "localhost";
$config['username'] = "jim";
$config['password'] = "password";
$config['database'] = "testdb";
$config['table_prefix'] = "td_";
$config['universal_admin_url'] = "http://www.jimclarke.co.uk/admin";
$config['base_url'] = "http://www.jimclarke.co.uk/";
$config['seo_page'] = "index2.php";
$config['show_errors'] = true;
$config['webmaster_email'] = 'me@example.com';
$config['webmaster_name'] = 'Administrator';
$config['language'] = 'english';
?>

Where am I going wrong?

Thanks
Jim

you probably need to escape $config
like \$config
and if you want double quotes you need to escape them too:

$input = "<?php
// Generated ".date('F j, Y H:i:s')."

// Database Details

\$config['hostname'] = \"$db_host\";


But you are not saying what's not working, are you getting error messages? is the file created?

Please explain "But its not working."

Is it producing an error or undesirable results?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

You should escape the dollar signs that do not point to a variable:

...
\$config['hostname'] = '$db_host';
\$config['username'] = '$db_user';
\$config['password'] = '$db_pass';
...

Sorry, it is just producing a parsing error. I thought I put that.

I will try escaping the $'s on each line. I just thought that being enclosed within " " they wiouldn't need escaping.

WIll report back shortly.

Thats what it was, I hadn't escaped the $'s at the beginning of each line.

Thank you.
