This is a followup to #2496943: Add condition to ignore PHP 7 on rest requirements check.
Problem/Motivation
As per David_Rothstein's comment in #2456025-28: PHP warnings in PHP 5.6 because of always_populate_raw_post_data ini setting (the D7 version of this issue):+ 'description' => t('The always_populate_raw_post_data PHP setting should be set to -1 in PHP versions 5.6 and up. Please check the <a href="https://php.net/manual/en/ini.core.php#ini.always-populate-raw-post-data">PHP manual</a> for information on how to correct this.'),
We usually like to leave the /en/ out of php.net URLs in the user interface. That way we don't assume a language and the user gets sent to the correct language via whatever mechanism php.net uses to detect that.
Proposed resolution
Remove '/en' part from URL. in the file (core/modules/rest/rest.install).
Optionally, run a search for php.net/manual/en through core files to see if you spot more occurrences.
Remaining tasks
Do it.
User interface changes
API changes
Data model changes
None.
