Feeble attempt to mimic `jq` functionality with PHP input. Usage: `echo filename.php | phpq '$.attr1.subattr1'`

phpq

#!/usr/bin/env php
<?php
$syntax = !empty($argv[1]) ? $argv[1] : "\$";

$input = preg_replace("/^<\?php/", "", trim(file_get_contents("php://stdin")));
$defvars = array_keys(get_defined_vars());

$parsed = eval($input);
$vars = get_defined_vars();

foreach($defvars as $key) unset($vars[$key]);

$target = $vars;
foreach(explode(".", $syntax) as $key) {
   if ($key == "\$") continue;
   if (is_object($target) && isset($target->$key)) {
     $target = $target->$key;
     continue;
   }
   if (is_array($target) && array_key_exists($key, $target)) {
      $target = $target[$key];
      continue;
   }
}

if (!is_scalar($target)) {
   echo print_r($target, 1);
} else {
   echo $target;
}

echo PHP_EOL;
