Script used to do mass import statement fixes in ZF2

replace-uses.php

<?php
echo "Analyzing {$argv[1]}\n";
$file    = file_get_contents($argv[1]);
$matches = null;
preg_match('/\n(use .*?)(?:\r?\n(?:\/\*|interface|abstract|class|trait))/s', $file, $matches);
if (!$matches || !$matches[1]) {
    echo "    Did not match initial pattern\n";
    exit(0);
}
// echo "    Matches: " . var_export($matches, 1) . "\n";
$matched = "\n" . $matches[1];
$uses    = array();
preg_replace_callback(
    '/\n(?:use\s+|\s*)([a-zA-Z][a-zA-Z0-9\\\\_]*( as [a-zA-Z0-9_]+)?)/', 
    function ($m) use (&$uses) {
        // echo "Callback matches: " . var_export($m, 1) . "\n\n";
        $uses[] = $m[1];
    }, 
    $matched
);
natcasesort($uses);
$uses = "\nuse " . implode(";\nuse ", $uses) . ";\n";
$replaced = str_replace($matched, $uses, $file);
file_put_contents($argv[1], $replaced);
echo "    Wrote changes\n";

To execute, I did the following from the library/Zend directory, using zsh:

for file in **/*;do
    php /path/to/replace-uses.php $file;
done
