Check if the Images already exit or not in the image folder using PHP function

Explaination:

By using PHP function if the Images already exit r not ion the image folder we have to check out using file_exists function r @get_headers.And for backgroung image we have to display in image folder means we have to take anyone has common such as id r name.
Here for example i took id we have to select and fetch with DB and that variable put itin to  the imagepath.


Note:Sometimes file_exists function will not work

Coding:

$url = "images/group_hotel_".trim($ID).".jpg";
$file_headers = @get_headers($url);
if($file_headers[0] == 'Not Found') {
    $banner = "images/group_hotel_nobanner.jpg";
} else {
    $banner = "images/group_hotel_".trim($ID).".jpg";
}

form:

Display the image as in image foldder

<div class="search_bg" style="background-image: url('<?php echo $banner; ?>');">
