Create Image Thumbnail on the fly

Today im not in the mood to explain more about this function but if you have any question, dont hesitate, just ask me in the comment section. Thanks.


function image_create_thumb($filename, $width, $height)
{
list($image["Width"], $image["Height"], $image["Type"]) = getimagesize($filename);


switch($image["Type"])
{
case IMG_JPG:
case IMG_JPEG:
$im_image = ImageCreateFromJPEG($filename);
break;
case IMG_GIF:
$im_image = ImageCreateFromGIF($filename);
break;
case IMG_PNG:
$im_image = ImageCreateFromPNG($filename);
break;
}

if($image["Width"] > $image["Height"])
{
$scale = $width / $image["Width"];
$thumb_width = $width;
$thumb_height = floor($image["Height"]*$scale);
}
else
{
$scale = $height / $image["Height"];
$thumb_height = $height;
$thumb_width = floor($image["Width"]*$scale);
}

$im_thumb = @ImageCreateTrueColor($thumb_width, $thumb_height) or die("Cannot Initialize new GD image stream");

ImageCopyResized($im_thumb, $im_image, 0, 0, 0, 0, $thumb_width, $thumb_height, $image["Width"], $image["Height"]);

ImageDestroy($im_image);
ImagePNG($im_thumb, $filename);
ImageDestroy($im_thumb);

return true;
}//image_create_thumb($filename, $width, $height)
?>

PHP Image Resizer

Today i give you a PHP tutorial about how to resize an image using PHP as your web programming language.

function resize_jpg($inputFilename, $new_side){
$imagedata = getimagesize($inputFilename);
$w = $imagedata[0];
$h = $imagedata[1];

if ($h > $w) {
$new_w = ($new_side / $h) * $w;
$new_h = $new_side;
} else {
$new_h = ($new_side / $w) * $h;
$new_w = $new_side;
}

$im2 = ImageCreateTrueColor($new_w, $new_h);
$image = ImageCreateFromJpeg($inputFilename);
imagecopyResampled ($im2, $image, 0, 0, 0, 0, $new_w, $new_h, $imagedata[0], $imagedata[1]);
return $im2;
}

Maybe this image resizing code using PHP is not the best of all but at least, it'll help you to do your job =)

Retrieve data from $_GET array

$q = explode("&",$_SERVER["QUERY_STRING"]);
foreach ($q as $qi)
{
if ($qi != "")
{
$qa = explode("=",$qi);
list ($key, $val) = $qa;
if ($val)
$$key = urldecode($val);
}
}

This code is similar to previous code but this one is for $_GET global variables. Good luck with your programming !!

Retrieve data from $_POST array

/**
* Retrieve PHP Post variable
*/
reset ($_POST);
while (list ($key, $val) = each ($_POST))
{
if ($val){
addslashes($val);
$$key = $val;
$_SESSION['data_advertiser'][$key] = $val;
}
}

so let say you have $_POST['name']. After this code to access this variable , what you have to do is just use $name instead of $_POST['name'] !!! so easy right?
