我在下面编写了这个函数来返回可以在 PDO 语句中使用的 $_POST 全局值。如果这是一个好方法,我只是想要建议。我知道“内爆”部分可能不是很灵活,但我想知道如何改进。非常感谢任何有关逻辑和改进功能的帮助。谢谢。
/**
* This function loops through the $_POST global and returns parameters that can be used in
* a PDO statement directly. Note : For this function to work properly the
* PDO::ATTR_EMULATE_PREPARES should be set to "false"
* like so "$conn->setAttribute(PDO::ATTR_EMULATE_PREPARES, false)".
* @param Array $exclude This is an array of keys in $_POST that you want the function to ignore
* @return Array The function returns an array that can be used as parameters for the PDO statement
*/
function get_params($exclude = array()) {
$keys = array();
$values = array();
$placeholder_keys = array();
$params = array();
foreach ($_POST as $key => $value) {
if(!in_array($key, $exclude)) {
$keys[] = $key;
$placeholder_keys[] = ":" . $key;
if(is_array($value)){
$value = implode(",", $value);
}
$values[] = $value;
}
}
$comma_sep_keys = implode(",", $keys);
$comma_sep_placeholder_keys = implode(",", $placeholder_keys);
$params['keys'] = $keys;
$params['values'] = $values;
$params['placeholder_keys'] = $placeholder_keys;
$params['comma_sep_keys'] = $comma_sep_keys;
$params['comma_sep_placeholder_keys'] = $comma_sep_placeholder_keys;
return $params;
}
