PHP normalize function

I post my normalization function. This function find all illegal characters (like: Ő, Ű, ú, í, etc. ) and replace it to latin1 chars. (like: O, U, u, i, etc.) This function works for me on hungarian words. Try it on your text and post your comment about it.

HTML number formatting with PHP

Here is my HTML number formatter. Sometimes the browsers wrap the numbers along thousand separator or decimal pont, but this function prevents this event.

function html_number_format($number, $decimals = 2, $dec_point = '.', $thousands_sep = ',') {
  if ($number === FALSE) {
    return '---';
  return '<span style="white-space: nowrap;">'.number_format($number, $decimals, $dec_point, $thousands_sep).'</span>';

PHP GD2 vs Imagick



function gd_thumbnail($filename, $width = 200, $height = 200) {
$source = imageCreateFromString(file_get_contents($filename));
$x = imageSX($source);
$y = imageSY($source);

if ($x > $y) { // landscape orientation
$height = intval($y/($x/$width));
} else { // square or portrait orientation
$width = intval($x/($y/$height));

$destination = ImageCreateTrueColor($width,$height);

* @return array that contains all public property name as key and their values. example:
