Previous Comments: ------------------------------------------------------------------------ [2017-03-15 20:17:50] requinix@php.net Duplicate of bug #64346. ------------------------------------------------------------------------ [2017-03-15 20:08:46] losborn at jnrcorp dot com Description: ------------ Unqualified function calls are supposed to resolve to functions within their namespace if they exist. This doesn't always happen if the in-namespace function doesn't exist when the calling function is defined. Seen issue on 5.6.28, 5.6.30, 7.1.2 More verbose example: https://paste.laravel.io/9qgML Test script: --------------- <?php namespace NotGlobalNamespace; eval('namespace F\\o\\o; function bar($marker) { echo "$marker => " . rand() . "\n"; }'); \F\o\o\bar(1); eval('function bar($m) { return \F\o\o\bar($m); }'); bar(2); eval('namespace F\\o\\o; function rand() { return "*** INTERCEPTED ***"; }'); \F\o\o\bar(3); bar(4); eval('namespace F\\o\\o; function baz($marker) { echo "$marker => " . rand() . "\n"; }'); \F\o\o\baz(5); eval('function baz($m) { return \F\o\o\baz($m); }'); baz(6); bar(7); Expected result: ---------------- 1 => 1059777682 (random) 2 => 1332050858 (random) 3 => *** INTERCEPTED *** 4 => *** INTERCEPTED *** 5 => *** INTERCEPTED *** 6 => *** INTERCEPTED *** 7 => *** INTERCEPTED *** Actual result: -------------- 1 => 1059777682 (random) 2 => 1332050858 (random) 3 => 1123318855 (random) 4 => 1146230506 (random) 5 => *** INTERCEPTED *** 6 => *** INTERCEPTED *** 7 => 360960634 (random) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=74253&edit=1
