PHP Simple E-Mail

  1. Altering the mail() options Dynamically with ini_set():
    • PHP's ini_set() function temporarily sets a given configuration option for the duration of the program that invoked it.
    • ini_set() takes two parameters
      • Varname – Variable/option to change
      • Newvalue – Value to change to
    • The following lines of code show how to set the SMTP server and "from" address within a PHP function.

Example:

<HTML>
<body>
MAIL SETTING for Iseries<br>
Define a real name of your mail Server<br>
<center>
SMTP = mail.zend.com </center>
<br>
Define a real name of your mail Server<br>
<center>
smtp_port = 25</center>
<br>
Define an any address you want<br>
<center>
sendmail_from = shlomo@zend.com</center><br>
</body>
 

<?php
// Using the ini_set()
ini_set("SMTP", "mail.zend.com");
ini_set("sendmail_from", "shlomo@zend.com");
//ini_set("smtp_port", "25");

// The message
$message = "The mail message was sent with the following mail setting:\r\nSMTP = mail.zend.com\r\nsmtp_port = 25\r\nsendmail_from = YourMail@address.com";

// Send
$headers = "From: shlomo@zend.com";

mail('shlomo@zend.com', 'My Subject', $message, $headers);

echo "Check your email now….<BR>";
?>
</HTML>

 

  1. Setting the mail() options Static php.ini parameters:
[mail function]
SMTP = mail.zend.com
smtp_port = 25
sendmail_from = shlomo@zend.com

Example:

<HTML>
<body>
MAIL SETTING for Iseries<br>
Define a real name of your mail Server<br>
<center>
SMTP = mail.zend.com </center>
<br>
Define a real name of your mail Server<br>
<center>
smtp_port = 25</center>
<br>
Define an any address you want<br>
<center>
sendmail_from = shlomo@zend.com</center><br>
</body>

 

<?php
// Using the php.ini static entries 

// The message
$message = "The mail message was sent with the following mail setting:\r\nSMTP = mail.zend.com\r\nsmtp_port = 25\r\nsendmail_from = YourMail@address.com";
// Send
$headers = "From: shlomo@zend.com";
mail('shlomo@zend.com', 'My Subject', $message, $headers);

echo "Check your email now….<BR>";
?>
</HTML>

 

Troubleshooting

  • Changes to PHP.INI will take effect after the Apache server is restarted
  • To view mail() unexpected behaviour, see PHP's error log: /usr/local/zend/Core/logs/php_error_log
  • The error log may be viewed with a text editor or this command: EDTF '/usr/local/zend/Core/logs/php_error_log'
Note:
Make sure the mail() extension is loaded use the GUI to load and enable the extension, than restart the apache from the i5 use the green screen menu: GO ZENDCORE/ZCMENU
