Question

Is this possible? <div id="example" title="is possible put PHP code here?"> some text </div>
I want put <?php the_excerpt(); ?> in the Title attribute

Answer 1

Yes.

<div id="example" title="<?php echo the_excerpt(); ?>"> some text </div>

or:

<div id="example" title="<?= the_excerpt() ?>"> some text </div>

The latter is a shorthand that automatically echoes everything in the PHP block, whereas the former can contain any code, including code that echoes something (prints it to where the block is).

See basic syntax.

Take note, however, to escape anything you output to HTML, to make sure it’s a valid attribute value (unless the_excerpt() already returns an escaped string):

<div id="example" title="<?= htmlspecialchars(the_excerpt()) ?>"> some text </div>
