Code sniffer for for converting snake_case to camelCase - coding-style

Question

I need a code sniffer for converting all the variables in all of my PHP file from snake_case to camelCase.
I don't need the functions which do it in php on a string, I want to convert the variables in my PHP files to camelCase.
I appreciate you in advanced.

Answer 1

I found a way to do it.
I integrate the code for cakePHP (There is the file with ctp extension and the variable passed to view by set function).
Save the below code as tocamelcase.php
php tocamelcase.php the/path/of/your/app
file content:
<?php
function snakeToCamel($val) {
preg_match('#^_*#', $val, $underscores);
$underscores = current($underscores);
$camel = str_replace('||||', '', ucwords(str_replace('_', '||||', $val), '||||'));
$camel = strtolower(substr($camel, 0, 1)).substr($camel, 1);
return $underscores.$camel;
}
function convert($str) {
global $j;
$name = '/(\$[a-zA-Z0-9]+_[a-zA-Z0-9_]+)|'.
'(->[a-zA-Z0-9]+_[a-zA-Z0-9_]+)|'.
'(::[a-zA-Z0-9]+_[a-zA-Z0-9_]+)|'.
'(\sfunction\s+[a-zA-Z0-9]+_[a-zA-Z0-9_]+)|'.
'(\$this->set\(\'[a-zA-Z0-9]+_[a-zA-Z0-9_]+\'\,)|'.
'(\$this->set\(\"[a-zA-Z0-9]+_[a-zA-Z0-9_]+\"\,)'.
'/i';
$str = preg_replace_callback($name, function($matches){
return snakeToCamel($matches[0]);
},$str);
return $str;
}
$path = $argv[1];
$Iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));
$i=1;
foreach($Iterator as $file){
if(substr($file,-4) !== '.php' && substr($file,-4) !== '.ctp')
continue;
echo($i.": ".$file."\n");
$i++;
$out = convert(file_get_contents($file));
file_put_contents($file, $out);
}
