A simple linter for code snippets. Writes the snippet to a temp file and then captures and returns the output of php's commandline lint

lint

<?php

function lint($code)
{
    $code = strpos($code, '<?php') === 0 ? $code : "<?php $code";
    $filename = tempnam(sys_get_temp_dir(), 'lnt');
    file_put_contents($filename, $code);
    exec(PHP_BINARY . " -l $filename", $errors);
    unlink($filename);
