How can I programmatically create and manipulate INI files in PHP?

Creating and Manipulating INI Files in PHP

PHP offers limited built-in functionality for managing INI files. This can be a challenge when you need to create new files or modify existing ones programmatically.

However, a useful solution can be found in the PHP documentation comments. Here's a code snippet that addresses this issue:

<code class="php">function write_ini_file($assoc_arr, $path, $has_sections=FALSE) {
    // Generate content based on the provided data structure
    $content = "";
    if ($has_sections) {
        // Handle sections and key-value pairs
        foreach ($assoc_arr as $key => $elem) {
            $content .= "[$key]\n";
            foreach ($elem as $key2 => $elem2) {
                if (is_array($elem2)) {
                    // Handle arrays within sections
                    for ($i = 0; $i < count($elem2); $i++) {
                        $content .= "$key2[] = \"$elem2[$i]\"\n";
                    }
                } elseif ($elem2 === "") {
                    // Handle empty key-value pairs within sections
                    $content .= "$key2 = \n";
                } else {
                    // Handle non-empty key-value pairs within sections
                    $content .= "$key2 = \"$elem2\"\n";
                }
            }
        }
    } else {
        // Handle flat INI file structure
        foreach ($assoc_arr as $key => $elem) {
            if (is_array($elem)) {
                // Handle arrays in flat structure
                for ($i = 0; $i < count($elem); $i++) {
                    $content .= "$key[] = \"$elem[$i]\"\n";
                }
            } elseif ($elem === "") {
                // Handle empty key-value pairs in flat structure
                $content .= "$key = \n";
            } else {
                // Handle non-empty key-value pairs in flat structure
                $content .= "$key = \"$elem\"\n";
            }
        }
    }

    // Write the generated content to the INI file
    if (!$handle = fopen($path, 'w')) {
        return false; // Unable to open the file
    }
    $success = fwrite($handle, $content);
    fclose($handle);

    return $success; // Return success status
}

Usage:

<code class="php">$sampleData = array(
    'first' => array(
        'first-1' => 1,
        'first-2' => 2,
        'first-3' => 3,
        'first-4' => 4,
        'first-5' => 5,
    ),
    'second' => array(
        'second-1' => 1,
        'second-2' => 2,
        'second-3' => 3,
        'second-4' => 4,
        'second-5' => 5,
    ),
);
write_ini_file($sampleData, './data.ini', true); // Write data to 'data.ini' with sections</code>
