Storing text and var values into a variable.

[psycovic23]

At the moment, I'm trying to write a script that creates and writes in a configuration file. I want to write in stuff such as:

$hostname = "$variable1";
$dbusername = "$var2";
$dbpassword = "$var3";

I'm using this to write it in.

if (fwrite($handle, $configuration) === FALSE) {
       echo "Cannot write to file ($filename)";
       exit;
   }

Is there anyway I can stick all of that into the $configuration variable? Right now, I'm doing crazy stuff like:

$configuration = '//database information
$hostname = ' . $localhost . ';
$dbusername = ' . $dbusername . ';
$dbpassword = ' . $dbpassword . ';';

But it never ends up printing the variables.

If I understand correctly you just need to escape the $s with a \$ I just typed this out real quick

<?php
        if(!($write = fopen("testMe.txt","w+"))){
                print("cant open");
                exit();
        }

    $hostname = "\$variable1";
    $dbusername = "\$var2";
    $dbpassword = "\$var3";

    $config = "//database info";
    $config .= "\$hostname = " . $hostname;
    $config .= "\$dbusername = " . $dbusername;
    $config .= "\$dbpassword = " . $dbpassword;

    fputs($write, $config);

    fclose($write);
?>

and got this as my out put
//database info
$hostname = $variable1
$dbusername = $var2
$dbpassword = $var3

HTH!!

not correct, although your code works...

$configuration = '//database information 
$hostname = ' . $localhost . '; 
$dbusername = ' . $dbusername . '; 
$dbpassword = ' . $dbpassword . ';';

using ' . $localhost . ' is adding (whats between brackets here)
[ . $localhost . ] in literal sense.

either use $hostname = $localhost;
or $hostname = " $localhost "; //if you need the white spaces on either end

the reason for this is 'strings enclosed like this' are considered static and not parsed for variables

"strings enclosed like this" are considered non static, so PHP will parse $variables in the string

and assing a variable like $var = $variable; will always parse the variable also

I ended up just doing this:

$hostname = $_GET['hostname'];
//database information
$hostname = "' . $hostname . '";

After //database information, that is printed into the file.
