Looks like it's an introduced bug since redefining functions still works well when functions had been called in the same file like the following : <?php namespace custom; var_export('hello'); //hello eval("namespace custom; function var_export(){echo 'foobar';}"); var_export('hello'); //foobar ?>It's pretty annoying since this feature allowed a king of monkey patching in PHP 5.3 for writing tests cases. With PHP 5.4 & 5.5, redefining functions only work in the same file like in the follwing example: <?php namespace custom; var_export('hello'); //hello eval("namespace custom; function var_export(){echo 'foobar';}"); var_export('hello'); //foobar ?>
