The following function gives the list

-width of image

-height of image

-resolution of the image

-how to create the image file inside your php

-how to get the image Resource

-hoe to get Extension of image file etc….

To get all this image related resource call the below function

echo $image_width = getImageWidth(/image/path/image.jpg)//here the correct image path should give

function getImageWidth($filename){

if(file_exists($filename))

{

$ext = getExtension($filename);//to get the image extension its defined bellow

if(!$ext)

return 0;

$img_src = getImageResource($ext, $filename);//to get the image resource its defined bellow

return imagesx($img_src);

}

return 0;

}

function getImageHeight($filename){

if(file_exists($filename))

{

$ext = getExtension($filename);

if(!$ext)

return 0;

$img_src = getImageResource($ext, $filename);

return imagesy($img_src);

}

return 0;

}

To get the image Extension here is the function

function getExtension($filename)//the filename is path of the image

{

if($filename == '')

return false;

$ext = substr( $filename, strrpos( $filename, "." )+1 );

return $ext;

}

To get the image resource to get the image width or height

So the following function gives you the resource of the image type

function getImageResource($ext, $filename)//the image extension and the image path should be given

{

$imageresource = '';

if($ext == "jpg" || $ext == "JPG" || $ext == "jpeg" || $ext == "JPEG"){

$imageresource = imagecreatefromjpeg($filename);

}

if($ext == "gif" || $ext == "GIF"){

$imageresource = imagecreatefromgif($filename);

}

if($ext == "bmp" || $ext == "BMP"){

$imageresource = imagecreatefromwbmp($filename);

}

if($ext == "png" || $ext == "PNG"){

$imageresource = imagecreatefrompng($filename);

}

/*if(!$imageresource){//if not valid image

return false;

}*/

return $imageresource;

}

And finally how to create image file by using the extension , image resource and destination filename. The following function create image file with this parameters

Parameter list for the function

//here $ext is extension of the image

//$imgresource is the resource of the image with the width and height this you can get by $dst_im = imagecreatetruecolor($width, $height);

//$dest_filename is the destination file name where you want to save the file

function createImagefile ($ext, $imgresource, $dest_filename)

{

$imgfile = false;

if($ext == "jpg" || $ext == "JPG" || $ext == "jpeg" || $ext == "JPEG"){

$imgfile = imagejpeg($imgresource, $dest_filename);

}

if($ext == "gif" || $ext == "GIF"){

$imgfile = imagegif($imgresource, $dest_filename);

}

if($ext == "png" || $ext == "PNG"){

$imgfile = imagepng($imgresource, $dest_filename);

}

if($ext == "bmp" || $ext == "BMP"){

$imgfile = imagewbmp($imgresource, $dest_filename);

}

/*if($imgfile)

return true;*/

return $imgfile;
