How can i cache php code

Hello Faisal Habib

You can’t cache php code. PHP is used to cache output of an operation.

i want to cache these files

mywebsite.com/embed/212

This is not a file but a rewritten url. I am not sure if I am following you properly. Would you please explain again? Maybe rephrase?

Have a good day!

Cheers
Ash

Thanx sir for reply,
here is my url https://dramaxima.com/embed/1834

1834 is post id here

function td_embed_generate(){

    if( is_admin() ) return;

    $current_url = esc_url( home_url( add_query_arg( NULL, NULL ) ) );

    if ( preg_match( "#^http.*\/embed\/\d{1,}#i", $current_url ) ) {

        $array_id = explode( '/', $current_url );

        $post_id = end( $array_id );

        if( ! is_numeric( $post_id ) ) return;

        $args = array(

            'p'              => $post_id,

            'posts_per_page' => 1

        );

        $embed = get_posts( $args );

        if ( ! isset( $embed[0]->ID ) ) return;

and this is code to get custom field from posts (using post id)

i want to cache these embed urls so every time they don’t fetch code from functions.php
