stream_get_contents

(PHP 5, PHP 7, PHP 8)

stream_get_contentsReads remainder of a stream into a string

Description

stream_get_contents(resource $stream, ?int $length = null, int $offset = -1): string|false

Identical to file_get_contents(), except that stream_get_contents() operates on an already open stream resource and returns the remaining contents in a string, up to length bytes and starting at the specified offset.

Parameters

stream ( resource)

A stream resource (e.g. returned from fopen())

length ( int)

The maximum bytes to read. Defaults to null (read all the remaining buffer).

offset ( int)

Seek to the specified offset before reading. If this number is negative, no seeking will occur and reading will start from the current position.

Return Values

Returns a string or false on failure.

Changelog

Version Description
8.0.0 length is now nullable.
