I need something that can be used in php programming and can work offline since, as we know, Google Maps requires an Internet Connection.

There isn’t a choice as php requires online to work.
You might interested on programming such as c++. it works offline without any hassle.

Yes it is possible use following code

<?php
require_once( "watermark.php" );

$original_directory = "pictures/";
$watermarked_images = "temp/";

if ($handle = opendir($original_directory))
{
while (false !== ($file = readdir($handle)))
{
if(!is_file($original_directory.$file))
continue;
if(exif_imagetype($original_directory.$file)==2)
{
watermark($original_directory.$file,
"watermark.png",
$watermarked_images.$file);
}
}
closedir($handle);
}
?>

function watermark($original_image,$original_watermark,$destination="")
{
$image=imagecreatefromjpeg($original_image);
list($imagewidth,$imageheight)=getimagesize($original_image);

$watermark = imagecreatefrompng($original_watermark);
list($watermarkwidth,$watermarkheight)=getimagesize($original_watermark);

if($watermarkwidth>$imagewidth || $watermarkheight>$imageheight)
{
$water_resize_factor = $imagewidth / $watermarkwidth;
$new_watermarkwidth = $watermarkwidth * $water_resize_factor;
$new_watermarkheight = $watermarkheight * $water_resize_factor;

$new_watermark = imagecreatetruecolor($new_watermarkwidth , $new_watermarkheight);

imagealphablending($new_watermark , false);
imagecopyresampled($new_watermark , $watermark, 0, 0, 0, 0, $new_watermarkwidth, $new_watermarkheight, $watermarkwidth, $watermarkheight);

$watermarkwidth = $new_watermarkwidth;
$watermarkheight = $new_watermarkheight;
$watermark = $new_watermark;
}
$startwidth = ($imagewidth – $watermarkwidth) / 2;
$startheight = ($imageheight – $watermarkheight) / 2;

imagecopy($image, $watermark, $startwidth, $startheight, 0, 0, $watermarkwidth, $watermarkheight);
if(!empty($destination))
imagejpeg($image,$destination);
else
imagejpeg($image);
}

Can it get you a job for Programming with a certified without a college degree??

Yes, I got a 40k+ a year job with nothing but an A+ and a resume. I personally think that experience beats out college education when it comes to development and design gigs.

i had .PHP FILE.but i want to preview and edit it and No need to know php programming language.what application to use so i just copy paste the item i want to desire place within the frame?

You can preview and edit a PHP file in whatever text editor you have on your system…such as Notepad on a Windows machine. However you don’t just copy and paste it into a frame to make it work. It is much more detailed than that.
