The flags in fopen calls must omit t, and b must be omitted or included consistently.

The b flag must be used (true) or omitted (false).

Allowed types: bool

Default value: true

Default configuration.

+$a = fopen($foo, 'rwb');

Example #2

With configuration: ['b_mode' => false].

--- Original
+++ New
-$a = fopen($foo, 'rwt');
+$a = fopen($foo, 'rw');
