Solution for “Fatal error: Maximum function nesting level of '100' reached, aborting!” in PHP

Question

I have made a function that finds all the URLs within an html file and repeats the same process for each html content linked to the discovered URLs. The function is recursiv

Answer 1

You can also modify the {debug} function in modifier.debug_print_var.php, in order to limit its recursion into objects.

Around line 45, before :

$results .= '
' . str_repeat(' ', $depth * 2)
  . ' ->' . strtr($curr_key, $_replace) . ' = '
  . smarty_modifier_debug_print_var($curr_val, ++$depth, $length);

After :

$max_depth = 10;
$results .= '
' . str_repeat(' ', $depth * 2)
  . ' ->' . strtr($curr_key, $_replace) . ' = '
  . ($depth > $max_depth ? 'Max recursion depth:'.(++$depth) : smarty_modifier_debug_print_var($curr_val, ++$depth, $length));

This way, Xdebug will still behave normally: limit recursion depth in var_dump and so on. As this is a smarty problem, not a Xdebug one!
