Dynamically change image titles and alt tags through PHP – On html render, not in database – WordPress

I want to re-title my image’s alt tags etc based on the page they are being displayed on. For SEO Purposes.

I’ve tried to write a PHP function to do so and call the function on page load with "alt=<?php echo $post_title ?>" and "title=<?php echo $post_title ?>" but nothing is working.

How would you do it? PHP or jQuery… or?

Here’s one of the functions I tried to manipulate and turn into something that works… I did get it to change the alt tags but I havent had any success beyond that.

function isa_add_img_title( $attr, $attachment = null ) {

    $img_title = trim( strip_tags( $attachment->post_title ) );

    $attr['title'] = $img_title;
    $attr['alt'] = $img_title;

    return $attr;
}
add_filter('wp_get_attachment_image_attributes','isa_add_img_title', 10, 2);

It appears this post may have had the answer but the link in the answer is now broken:
Dynamically filling image alt tags with the page title, PHP

Thanks so much! Appreciate any help.

    This will set the alt and title of every image on the page to the post title.

    function duck_diver_add_img_title( $attr, $attachment = null ) {
    // Fetch the global post object. This is what the page it's on is.
    global $post;
    // Get the post title.
    $img_title = wp_kses_post( $post->post_title );

    $attr['title'] = $img_title;
    $attr['alt']   = $img_title;

    return $attr;
}
add_filter( 'wp_get_attachment_image_attributes', 'duck_diver_add_img_title', 10, 2 );
