run code in 300+ PHP versions simultaneously
<?php $versions = [1, 1.0, '1', '1.0', 'a1.0', '1.0a', TRUE]; foreach ($versions as $version) { $data['version'] = $version; print "----------------------\n"; var_dump($data['version']); var_dump((float) $data['version']); var_dump((float) $data['version'] !== 1.0); print "\n"; }
Output for git.master_jit, git.master, rfc.property-hooks
