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

Creating and Manipulating INI Files Effortlessly with PHP

PHP lacks inherent functions specifically designed for managing INI files, making it challenging to create or modify them dynamically. However, a versatile solution can be found in the following code snippet, which enables you to effortlessly create and manipulate INI files.

<code class="php">function write_ini_file($assoc_arr, $path, $has_sections=FALSE) { 
    $content = ""; 
    if ($has_sections) { 
        foreach ($assoc_arr as $key=>$elem) { 
            $content .= "[".$key."]\n"; 
            foreach ($elem as $key2=>$elem2) { 
                if(is_array($elem2)) 
                { 
                    for($i=0;$i<count($elem2);$i++) 
                    { 
                        $content .= $key2."[] = \"".$elem2[$i]."\"\n"; 
                    } 
                } 
                else if($elem2=="") $content .= $key2." = \n"; 
                else $content .= $key2." = \"".$elem2."\"\n"; 
            } 
        } 
    } 
    else { 
        foreach ($assoc_arr as $key=>$elem) { 
            if(is_array($elem)) 
            { 
                for($i=0;$i<count($elem);$i++) 
                { 
                    $content .= $key."[] = \"".$elem[$i]."\"\n"; 
                } 
            } 
            else if($elem=="") $content .= $key." = \n"; 
            else $content .= $key." = \"".$elem."\"\n"; 
        } 
    } 

    if (!$handle = fopen($path, 'w')) { 
        return false; 
    }

    $success = fwrite($handle, $content);
    fclose($handle); 

    return $success; 
}

Usage:

The provided code snippet can be implemented as follows:

<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);</code>

Output:

The following INI file will be generated at the specified path:

[first]
first-1 = 1
first-2 = 2
first-3 = 3
first-4 = 4
first-5 = 5

[second]
second-1 = 1
second-2 = 2
second-3 = 3
second-4 = 4
second-5 = 5
