create ini file, write values in PHP

Question

I cannot find a way that easily lets me create a new file, treat it as an ini file (not php.ini or simiilar... a separate ini file for per user), and create/delete values using PHP. PHP seems to offer no easy way to create an ini file and read/write/delete values. So far, it's all just "read" - nothing about creating entries or manipulating keys/values.

Answer 1

I can't vouch for how well it works, but there's some suggestions for implementing the opposite of parse_ini_file (i.e. write_ini_file, which isn't a standard PHP function) on the documentation page for parse_ini_file.

You can use write_ini_file to send the values to a file, parse_ini_file to read them back in - modify the associative array that parse_ini_file returns, and then write the modified array back to the file with write_ini_file.

Does that work for you?

Found following code snippet from the official PHP documentation:

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 .= $key2."[] = \"".$elem[$i]."\"\n"; 
                } 
            } 
            else if($elem=="") $content .= $key2." = \n"; 
            else $content .= $key2." = \"".$elem."\"\n"; 
        } 
    } 

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

Usage:

$sampleData = array(
                'first' => array(
                    'first-1' => 1,
                    'first-2' => 2,
                    'first-3' => 3,
                    'first-4' => 4,
                    'first-5' => 5,
                ),
                'second' => array(
                    'second-1' => 1,
                    'second-2' => 2,
                    'second-3' => 3,
                    'second-4' => 4,
                    'second-5' => 5,
                ));
write_ini_file($sampleData, './data.ini', true);

Good luck!

Hi there,

in this portion of code:

else { 
    foreach ($assoc_arr as $key=>$elem) { 
        if(is_array($elem)) 
        { 
            for($i=0;$i<count($elem);$i++) 
            { 
                $content .= $key2."[] = \"".$elem[$i]."\"\n"; 
            } 
        } 
        else if($elem=="") $content .= $key2." = \n"; 
        else $content .= $key2." = \"".$elem."\"\n"; 
    } 
} 

$key2 must be replaced by $key or you would find empty keys in your .ini
