If you want to check if a remote image file exists on a WordPress site but don’t necessarily want to fetch or download that file, this lightweight helper function can be used for that purpose:
| <?php | |
| /** | |
| * Check if a remote image file exists. | |
| * | |
| * @param string $url The url to the remote image. | |
| * @return bool Whether the remote image exists. | |
| */ | |
| function km_remote_image_file_exists( $url ) { | |
| $response = wp_remote_head( $url ); | |
| return 200 === wp_remote_retrieve_response_code( $response ); | |
| } |
Example Usage
It can be used like this:
| <?php | |
| $image_url = 'https://www.google.com/images/branding/googlelogo/2x/googlelogo_color_272x92dp.png'; | |
| if ( km_remote_image_file_exists( $url ) ) { | |
| echo 'The remote image exists! Hooray!'; | |
| } else { | |
| echo 'The remote image does not exist. Boooooo.'; | |
| } |
