下面仅使用mime类型来验证文件，然后检查两者的大小。有关大多数MIME类型的列表，请参见此处或google。
function allowed_file(){//Add the allowed mime-type files to an 'allowed' array $allowed = array('application/doc', 'application/pdf', 'another/type');//Check uploaded file type is in the above array (therefore valid) if(in_array($_FILES['resume']['type'], $allowed) AND in_array($_FILES['reference']['type'], $allowed)){ //If filetypes allowed types are found, continue to check filesize: if($_FILES["resume"]["size"] < 400000 AND $_FILES["reference"]["size"] < 400000 ){ //if both files are below given size limit, allow upload //Begin filemove here.... } }}
