我创建了一个处理数组以及单个GET或POST值的函数function subVal($varName, $default=NULL,$isArray=FALSE ){ // $isArray toggles between (multi)array or single mode
$retVal = "";
$retArray = array();
if($isArray) {
if(isset($_POST[$varName])) {
foreach ( $_POST[$varName] as $var ) { // multidimensional POST array elements
$retArray[]=$var;
}
}
$retVal=$retArray;
}
elseif (isset($_POST[$varName]) ) { // simple POST array element
$retVal = $_POST[$varName];
}
else {
if (isset($_GET[$varName]) ) {
$retVal = $_GET[$varName]; // simple GET array element
}
else {
$retVal = $default;
}
}
return $retVal;}例子：$curr_topdiameter = subVal("topdiameter","",TRUE)[3];$user_name = subVal("user_name","");
