PHP Streams

PHP Custom Stream Filters

29th December 2019
Stream filters allow changes to be made to textual data in streams. This allows text to be changed when writing to or reading from streams, instead of changing the text after the stream has been run. There is a framework built into PHP that allows custom filters to be added to the group of built in filters.

PHP Custom Stream Wrappers

24th December 2019
Part of the strength of PHP's stream wrappers is the ability to add our own stream wrappers to the list of available wrappers. We can therefore natively open any type of resource just by registering a stream wrapper and then using the normal fopen() functions. The custom stream wrapper functionality is made possible through a few functions built into PHP.
