Cannot redeclare Send_mail() error - php

Question

I m trying to make a function which can check the database for active customer whose status is 1 if active, they should receive email.
For Email Functionality I had used PHP Mailer function.
Below is my script:
<?php
include '../mailer/class.phpmailer.php';
$sqlx = mysql_query("SELECT * from `cust");
$numRows = mysql_num_rows($sqlx);
$mail_body = '';
while($row = mysql_fetch_array($sqlx))
{
// fetch email
$uid = $row["uid"];
$email = $row["email"];
$count = "20";
if($count <= '70')
{
$f_name = "abc";
$f_email = "abc#xyz.com";
$mail_body = "Hii message";
$subject = "Hi you got notificaiton";
$headers = "From: abc <abc#xyz.com>";
$headers .= "Content-type: text/html\r\n";
function Send_mail($email, $subject, $headers, $mail_body, $f_email, $f_name)
{
$mail = new PHPMailer();
$Email = $email;
$fname = $f_name;
$femail = $f_email;
//==================smtp mail ===============================//
$mail->IsSMTP(); // telling the class to use SMTP
$mail->SMTPAuth = true;
$mail->Port= 25; // Sets the default SMTP server port.
$mail->SMTPSecure= 'tls'; // Options are "", "ssl" or "tls"
$mail->Host = 'localhost'; // SMTP server
$mail->Username = 'abc#xyz.com'; // Sets SMTP username.
$mail->Password = '1234556'; //Sets SMTP password.
//=========================================================//
$fname = $f_name;
$femail = $f_email; // email address of reciever
$mail->WordWrap = 50; // set word wrap
$mail->IsHTML(true); // send as HTML
$mail->Subject = $subject; // subject of mail
$mail->Body = $mail_body; // body of mail
$mail->Send(); return true;
}
$mail_result=Send_Mail($email, $subject, $headers, $mail_body,$f_email, $f_name);
}
}
?>
But i getting error:
You must provide at least one recipient email address.
Fatal error: Cannot redeclare Send_mail() (previously declared in C:\xampp\htdocs\testing\update.php:161) in C:\xampp\htdocs\testing\update.php on line 161

Answer 1

check your cust table there must be entered email address on which you are trying to send email. And change your
$mail->Port= 587;
$mail->SMTPSecure= 'tls';
$mail->Host = 'smtp.gmail.com';
$mail->Username = 'abc#gmail.com';//Valid Gmail address
$mail->Password = '1234556';//Gmail password
if still getting error you can go to your gmail account setting and allow for secure app authentication.

Answer 2

take your function outside of loop.Change your code structure to this.
function Send_mail($email, $subject, $headers, $mail_body, $f_email, $f_name)
{
................//code
$mail->Send(); return true;
}
while($row = mysql_fetch_array($sqlx))//use mysqli or PDO
{
.......//code
if($count <= '70')
{
.......//code
$mail_result=Send_mail($email, $subject, $headers, $mail_body,$f_email, $f_name);
}
}

Answer 3

Put your function outside of the loop. Here is the code structure:
<?php
include '../mailer/class.phpmailer.php';
function Send_Mail($email, $subject, $headers, $mail_body, $f_email, $f_name)
{
$mail = new PHPMailer();
$Email = $email;
$fname = $f_name;
$femail = $f_email;
//==================smtp mail ===============================//
$mail->IsSMTP(); // telling the class to use SMTP
$mail->SMTPAuth = true;
$mail->Port= 25; // Sets the default SMTP server port.
$mail->SMTPSecure= 'tls'; // Options are "", "ssl" or "tls"
$mail->Host = 'localhost'; // SMTP server
$mail->Username = 'abc#xyz.com'; // Sets SMTP username.
$mail->Password = '1234556'; //Sets SMTP password.
//=========================================================//
$fname = $f_name;
$femail = $f_email; // email address of reciever
$mail->WordWrap = 50; // set word wrap
$mail->IsHTML(true); // send as HTML
$mail->Subject = $subject;// subject of mail
$mail->Body = $mail_body; // body of mail
$mail->Send();
return true;
}
$sqlx = mysql_query("SELECT * from `cust");
$numRows = mysql_num_rows($sqlx);
$mail_body = '';
while($row = mysql_fetch_array($sqlx))
{
// fetch email
$uid = $row["uid"];
$email = $row["email"];
$count = "20";
if($count <= '70')
{
$f_name = "abc";
$f_email = "abc#xyz.com";
$mail_body = "Hii message";
$subject = "Hi you got notificaiton";
$headers = "From: abc <abc#xyz.com>";
$headers .= "Content-type: text/html\r\n";
$mail_result=Send_Mail($email, $subject, $headers, $mail_body,$f_email, $f_name);
}
}
?>
