很多php框架，将form的生成写在函数，这是无可厚非的，但是你无法接收在生成一个form的时候，循环调用用户函数所付出的性能成本，这时候，构建一个php和html混编的代码，远比循环执行函数的性能要高。
而且，多数时候，我们知道一个数据对象的结构，也已经定义了数据对象的每个字段的值类型，我们真的没有必要再去手动写什么form，或者还要用代码去判断，这个用select，那个用textarea什么的。 getformcolumns($data); if (empty($columns) || !is_array($columns)) { echo 'undefine form columns!'; } else { // 生成該模塊的前綴 if (!isset($prefix)) $prefix = strtolower($model); else $prefix = mst_string::tableize($prefix); if (!isset($id)) $id = $prefix . '_form'; if (!isset($class)) $class = $prefix . '-form'; $errors = $data->geterrors(); // 初始化form配置 // 定制提交的action if (!isset($action)) $action = $this->params->uri; // method if (!isset($method)) $method = 'post'; else { $method = strtolower((string)$method); if ($method != 'get' && $method != 'post') $method = 'post'; } // 是否需要上傳 if (!isset($isupload)) $isupload = true; // 定制提交按鈕的文字 if (!isset($submittext)) $submittext = 'submit'; // 定制label部分的寬度 if (!isset($headwidth)) $headwidth = 130; $headwidth = is_numeric($headwidth) && $headwidth > 0 ? $headwidth : 120; if (!isset($continueform)) $continueform = false; // 重載 if (!isset($linestart)) $linestart = 1;?>> $column) { // 跳過$column[0]為空的部分 if (!isset($column[0])) continue; // 定制一行的$column常用變量 $key = strtolower(trim($key)); $columnid = $prefix .
