PHP获取所有扩展及扩展下的所有函数签名生成php.snippet

 <?php
 $ext_info = array();
 $modules = get_loaded_extensions();
 foreach ($modules as $module) {
     $functions = get_extension_funcs($module);
     if (empty($functions) || !is_array($functions)) {
         continue;
     }
     foreach ($functions as $fun) {
         $reflect = new ReflectionFunction($fun);
         $params = $reflect->getParameters();//获取函数参数信息
         $param_str = '';
         $param_num = 0;
         if (!empty($params) && is_array($params) && count($params)>0) {
             foreach($params as $key=>$param) {
                 if($param->getName() !== '') {
                     $param_str .= '$${'.($key+1).':'.$param->getName().'}, ';
                 }
                 $param_num++;
             }
             $param_str = substr($param_str, 0, -2);
         }
         if (empty($param_str)) {
             echo "snippet $fun\n";
             echo "\t".$fun.'('.$param_str.')${1}'."\n";
         } else {
             echo "snippet $fun\n";
             echo "\t".$fun.'('.$param_str.')${'.($param_num+1).'}'."\n";
         }
     }
