Problem with PHP "require"

[ben1960]

I'm experiencing a problem with the Sonic server that doesn't occur in my development environment, which uses PHP 5.6.28.

This script also works without problems on the Netfirms.com server, which uses PHP 5.3.

When a PHP script requires an external PHP file, the Sonic server considers headers to have been sent. This means that I can't use the Location header in my PHP scripts.

It's extremely likely that you need to turn on output buffering:
For a custom php.ini or .user.ini:

Code: Select all

output_buffering = On

-or-
For .htaccess:

Code: Select all

php_flag output_buffering on

If that doesn't help, I recommend trying the troubleshooting tips that are mentioned in this StackOverflow post:

In short:
- An optional fix may be to enable output_buffering
- Look at the exact error message complaining about 'Headers already sent' - it should include the file and line number where the error occurred - work from there backwards. There should also be a 'output started at' section in the error that tells you the offending file and line that have generated output prior to your attempting to modify the header.

Joe was right. The problem was caused by output buffering being turned off. Joe's first suggestion, involving .user.ini solved the problem. However, the solution involving .htaccess did not work.

Joe's advice regarding the evaluation of error messages is excellent.

Thank you for your help Joe.
