How to Read and Write Values in PHP INI Files?

Editing and Reading PHP INI File Values

For reading INI file values in PHP, you can utilize the parse_ini_file function. Simply call it with the INI file path as an argument. For instance:

<code class="php">$ini_array = parse_ini_file("sample.ini");</code>

This will store the values in an array where the INI section names represent the keys and the values are stored as array elements. To access the value for "lu_link" or "footerbg", you can use:

<code class="php">$lu_link = $ini_array['lu_link'];
$footerbg = $ini_array['footerbg'];</code>

Writing back to the INI file is not as straightforward as reading. However, one efficient method involves using the write_php_ini function:

<code class="php">function write_php_ini($array, $file) {
    $res = [];
    foreach ($array as $key => $val) {
        if (is_array($val)) {
            $res[] = "[{$key}]";
            foreach ($val as $skey => $sval) {
                $res[] = "{$skey} = " . (is_numeric($sval) ? $sval : '"{$sval}"');
            }
        } else {
            $res[] = "{$key} = " . (is_numeric($val) ? $val : '"{$val}"');
        }
    }
    safefilerewrite($file, implode("\r\n", $res));
}</code>

In this function, safefilerewrite is used to safely rewrite the file to avoid overwriting issues. It utilizes a lock mechanism to prevent collisions and ensure data integrity.

To use this function, you simply pass an array with the desired INI values and the INI file path as arguments:

<code class="php">$ini_values = ['lu_link' => '#EF32AB', 'footerbg' => '#000000'];
write_php_ini($ini_values, "sample.ini");</code>
