Can we see liberary files where PHP readymade functions are declared.

Hi all,

i am using this code to write csv file.
================================================
function csvwriter($filecontents=null){
error_reporting(E_ALL ^ E_NOTICE);
$arr = $_SERVER["SCRIPT_FILENAME"];
$arr2 = explode("/",$arr);

$fruit = array_pop($arr2);



$path = implode("/",$arr2)."/";
$fp = fopen($path.'logfile.csv','w');
//pr($filecontents);
foreach ($filecontents as $line) {
fputcsv($fp,split(',',$line));
}
fclose($fp);
return true;
}//end function.
=======================================================

It says you need PHP 5.1.0 or above

 

Kaizoku is right. If you have to use the older version of PHP, follow the link that Kaizoku gave and check the first comment on the page: it has an implementation written in PHP for older versions.
