<?php
function write_system_config_file($path)
{
    $content = file_get_contents(__DIR__.'/'.SYSTEM_CONFIG_FILENAME);
    $config['{DATE_GENERATED}'] = date('r');

$config was never initialized. Although not strictly required by PHP, it is generally a good practice to add $config = array(); before regardless.

    $config['{SECURITY_KEY}'] = md5(uniqid(rand().time()));

    foreach ($config as $key => $value) {
        $content = str_replace($key, $value, $content);
    }
    $fp = @fopen($path, 'w');

    if (!$fp) {

$fp is of type false|resource, thus it always evaluated to false.

        echo '<strong>
                <font color="red">Your script doesn\'t have write access to the config directory</font></strong><br />
                <em>('.str_replace('\\', '/', realpath($path)).')</em><br /><br />
                You probably do not have write access on Chamilo root directory,
                i.e. you should <em>CHMOD 777</em> or <em>755</em> or <em>775</em>.<br /><br />
                Your problems can be related on two possible causes:<br />
                <ul>
                  <li>Permission problems.<br />Try initially with <em>chmod -R 777</em> and increase restrictions gradually.</li>
                  <li>PHP is running in <a href="http://www.php.net/manual/en/features.safe-mode.php" target="_blank">Safe-Mode</a>.
                  If possible, try to switch it off.</li>
                </ul>

                Please go back to step 5.
                <p><input type="submit" name="step5" value="&lt; Back" /></p>

        exit;

Using exit here is not recommended.

    fwrite($fp, $content);
    fclose($fp);
