我需要获取"fsdfsdf"的字符长度。谁能帮助我？:)
$array = array(
'Firstname' => $wpdb->escape($_REQUEST['Firstname']),
'Lastname' => $wpdb->escape($_REQUEST['Lastname']),
'Phone' => $wpdb->escape($_REQUEST['Phone']),
'Email' => $wpdb->escape($_REQUEST['Email'])
);
print_r（$array）：
Array
(
[Firstname] => fsdfsdf
[Lastname] =>
[Phone] =>
[Email] =>
)
$char_length = strlen($array['Firstname']);
试试这个，
$length = strlen($array[Firstname]);
echo $length;
希望对您有所帮助，
echo strlen(trim($array['Firstname']));
