run code in 300+ PHP versions simultaneously
<?php $needsVersion = '5.2'; $versions = ['5', '5.x', '5.1', '5.2', '5.2-dev', '5.2.0', '5.2.1', '5.3']; foreach ($versions as $version) { if (version_compare($version, $needsVersion, '>=')) { echo "{$version} >= $needsVersion\n"; } else { echo "{$version} < $needsVersion\n"; } }
Output for git.master, git.master_jit, rfc.property-hooks
