Question

I am running a PHP script as a cron job. An email is fired iff the script generates an output. Unfortunately, even if it does not output anything, an email is fired with:

Content-type: text/html

How can I get rid of this automatic Content-type: text/html generation triggering an email?

Answer 1

Use the -q switch on the php command:

php -q whatever.php

This stands for “quiet”, and will prevent php from outputting web headers that it normally would.

Alternatively, if you want to be explicit and more verbose, you can use --no-header:

php --no-header whatever.php
