Installation: Writing data to a variable, in another file

[3raser]

Say I have an installation file, and they type in all their database information & click submit. How would I get that information to open up a file called config.php, and write to the $db_host, $db_pass, $db_user, and $db variables only?

 

Is this possible? Thanks!

Write the information to file example below from http://www.tizag.com/phpT/filewrite.php

 

$myFile = "testFile.txt";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = "Bobby Bopper\n";
fwrite($fh, $stringData);
$stringData = "Tracy Tanner\n";
fwrite($fh, $stringData);
fclose($fh);

No, no, no. I know how to do that. But is it possible to write certain information to equal certain variables? I've had a member on here give me the code to do something like this, but I never bothered to learn the code and study it. So I regret that. <.<

You CAN write php code to a file. You would need to write the opening and closing php tags to the file so that the result was a valid .php code file that could be included by other .php files.

the examplke given is doing exactly what you need to be able to write a new file, you can make it write whatever you want. including php variables etc.

im not sure of away to do what you are asking but I do understand what you mean you want to use a script to define the variables in the config.php page sadly i dont know how to do that but you can do this:

 

<?php


if(isset($_POST['install_config_do'])) {
$db_host = $_POST['db_host'];
$db_pass = $_POST['db_pass'];
$db_user = $_POST['db-user'];
$db = $_POST['db.php'];

$myFile = "config.php";
$fh = fopen($myFile, 'w') or die("can't open file");
$stringData = '
<?php \n\n

$db_host = '.$db_host.'\n
$db_user = '.$db_user.'\n
$db_pass = '.$db_pass.'\n
$db = '.$db.'\n\n

mysql_connect("$db_host", "$db_user", "$db_pass") or die(mysql_error());
mysql_select_db("$b") or die(mysql_error());
';
fwrite($fh, $stringData);
fclose($fh);

} else {

echo "<form action='' method='post'>";
echo "<table border='0'>";
echo "<tr>";
echo "<td>DB Host:</td><td><input type='text' name='db_host'></td>";
echo "</tr><tr>";
echo "<td>DB User:</td><td><input type='text' name='db_user'></td>";
echo "</tr><tr>";
echo "<td>DB Pass:</td><td><input type='password; name='db_pass'></td>";
echo "</tr><tr>";
echo "<td>DB Name:</tr><td><input type='text' name='db'></td>";
echo "</tr><tr>";
echo "<td> </td><td><input type='submit' name='install_config_do' value='Install Config.php'></td>";

}
?>
