如何在当前范围内转储所有PHP变量？

Question

I need this for debugging purposes and need to dump all variables. Is there a way to get all variables? and is there any way to trace all calls after script ends? without changing my code. Note that i can't use xdebug or anything installable because my script is runnign on a host.

Answer 1

Check out the get_defined_vars function within PHP.

This function returns a multidimensional array containing a list of all defined variables, be them environment, server or user-defined variables, within the scope that get_defined_vars() is called.

Answer 2

You can try using get_defined_vars .

<?php
    $a = 12;
    $b = "foo";
    $bar = "test";

    echo '<pre>';
    print_r(get_defined_vars());
?>
