Sorry...i'm just asking for help, to create a successful foreach loop that can sent to many recipient...thats all i need

i've known the error but cant find a way to create a foreach loop whereby it will send a sms towards every recipient entered in the form, here's the part where looping is done <?php error_reporting(E_ALL ^ E_NOTICE); //Example $gsm_send_sms = new gsm_send_sms(); $gsm_send_sms->debug = false; $gsm_send_sms->port = 'COM6'; $gsm_send_sms->baud = 115200; $gsm_send_sms->init(); $name="CTL_TEL[]"; foreach ($_POST['CTL_TEL'] as $tel) { $status = $gsm_send_sms->send($_POST["CTL_TEL"] , $_POST["CTL_MSG"]); $status = $gsm_send_sms->send($tel , $_POST["CTL_MSG"]); if ($status) { echo "Message sent\n"; } else { echo "Message not sent\n"; } } $gsm_send_sms->close();

already changed, but still got an error

Hi! i'm currently have a problem using PHP in order to create a form that has the capability to send sms by using GSM modem, by the way, the modem that i'm using right now is Huawei E173 Broadband. I know there has been a lot of way to send sms using php but most of it is by using SMS Gateway, (eg like nowsms) To the problem, I wanna know how do i make this form below to send sms, now i've know that my modem is on COM6, so how do i integrate this form below here with GSM modem to send sms by using php+ So now i really need help here to teach me and guide me so that i can make php uses gsm modem to send sms.

i want to make this upload form to display a notification (there is no file chosen) when the submit button is clicked and also to make the submit button allow file that is below 3MB to be uploaded and deny any file that is more than 3MB by displaying message (max file size)

i didnt understand much, tried on some coding on the link, but didnt work like i'm expected

Hello, i have a problem in developing a secure file upload/download system using php, whereby in this code, there is no restriction in choosing any file type, but there is restriction on file size. and the file info will be stored in the database. Problem # i'm stucked in creating a upload form whereby there is an message box popped out saying "there is an error due to no file selected" when i click on the upload button without selecting any file # need help in setting the file size below 3MB whereby if i upload file more than 3MB there will be a message box popped out saying "maximum file size!" instead of showing Undefined index: on top of the browser Here are the code in uploadaction.php here are the form in download.php * the form is on download.php whereby it will refer to uploadaction.php to do the upload i've tried to find code from other sources but it didnt help, would love if javascript coding can be added to improve this coding. Thank you so much~
