run code in 300+ PHP versions simultaneously
<?php $a = "hello"; $b = "world"; //echo "{$a $b}\n"; // This causes a Parse error: syntax error, unexpected '$b' (T_VARIABLE), expecting } echo "{{$a} $b}\n"; // but you can escape the sequence -- why is the escape sequence character still a part of the output?
Output for git.master, git.master_jit, rfc.property-hooks
{hello world}
