for example see this code <?php declare(ticks=1); function my_function() { echo print_r(debug_backtrace(), 1) . '<br/>'; } register_tick_function('my_function', true); $t = false; $check = ['a']; foreach ($check as $e) { $t = false; if ($t===false) { break; // break; } else { delete_db(); // =) } } function delete_db() {} --- analysis show me that execute delete_db, and this is problem I see that in the alpha version of php 7.4 there is no such problem, all of a sudden, it pleases, here now to get a patch for php 7.1
