Reviewing and updating PHP settings

Tue, 14 May 2019 18:35:24 GMT

PHP settings are reviewed and updated by uploading the two corresponding files to a hosted site. To view the current PHP settings, a phpinfo script. To make changes to those settings, a user.ini settings file.

phpinfo

phpinfo is used to display the current PHP configuration for the site / server. Specific parameters can be passed to customize the output or to display all information the following syntax can be used:

<?php
phpinfo();
?>

The syntax would be added to a PHP file, uploaded to the site and viewed in a browser. An example script can also be found in the .zip in the Sample section below.

user.ini

A site's PHP settings can be adjusted by creating a user.ini file, adding the appropriate syntax (see Sample), then uploading that file to the document root of the site via FTP.

Sample

An example of a common update is the post_max_size and upload_max_filesize settings, often changed to allow plugin and theme uploads through WordPress.

For PHP 7.0, the settings default to 8 MB and 2 MB, respectively, which can lead to some upload errors within WordPress. To increase those settings, for example to 60 MB, create a new text document with the following syntax:

post_max_size = 60M
upload_max_filesize = 60M

Once the user.ini has been uploaded, to see the setting updates reflected on the site, first recycle the application pool at DiscountASP Control Panel > IIS Tools > Recycle ("Recycle App Pool" if IIS 7).

Once recycled, the new Local Value should be reflected when reviewing a phpinfo script.

For an example phpinfo script and user.ini file, download phpSettings.zip.

Send mail using Mail.php / PEAR

Tue, 19 Jun 2018 17:14:12 GMT

To send mail using Mail.php, PEAR and a user.ini, defining the path to PEAR, need to be uploaded to the site. With package and setup instructions below.

Download PEAR.zip

daspPear.zip

Inside the .zip is the PEAR directory, an example user.ini and a test script zsend.php. The PEAR directory contains a web.config to prevent browser access to the subdirectory. And please note that both the user.ini and the test script have to be configured before use.

Update and upload user.ini and PEAR directory

If the site has an existing user.ini, it will need to be updated with the server path to the PEAR directory. If the site does not have a user.ini, you can use the example file included in daspPEAR.zip.

The Server Path is found in the Account Info / Edit section of the DiscountASP Control Panel.

If using the example user.ini, only the "username" in the path needs to be updated to match the server path in the Account Info / Edit section:

include_path=".;e:\web\username\htdocs\pear\"

After updating the user.ini, upload it and PEAR to the document root of your site and Mail.php is ready for use.

Testing Mail.php

zsend.php may be used to test whether Mail.php has been properly set up. Open the file in a text editor and update the settings highlighted in red below.

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
require_once "Mail.php";
$from = "postmaster@domain.com";
$to = "postmaster@domain.com";
$subject = "Mail.php test email";
$body = "Test email sent using Mail.php.";
$host = "sm##.internetmailserver.net";
$username = "postmaster@domain.com";
$password = "password";
$headers = array ('Date' => date('r'),
  'From' => $from,
  'To' => $to,
  'Subject' => $subject,
  'Message-ID' => '<' . time() . md5($from . $to) . '@domain.com>');
$smtp = Mail::factory('smtp',
  array ('localhost' => $host,
  'host' => $host,
  'auth' => true,
  'username' => $username,
  'password' => $password));
$mail = $smtp->send($to, $headers, $body);
echo "Mail.php test"
?>

Once updated, save the changes and upload the script to the site. View the page in a browser and you should see "Mail.php test" returned. If the email is not received, the path to PEAR in the user.ini and/or the zsend.php settings should be reviewed.

To prevent abuse, zsend.php should be deleted from the site after testing.
