stream_set_blocking

Description

The stream_set_blocking of Stream for PHP set blocking/non-blocking mode on a stream.

Syntax

stream_set_blocking(
    resource $stream,
    bool $enable
): bool

Parameters

stream

The stream.

enable

If enable is false, the given stream will be switched to non-blocking mode, and if true, it will be switched to blocking mode. This affects calls like fgets() and fread() that read from the stream. In non-blocking mode an fgets() call will always return right away while in blocking mode it will wait for data to become available on the stream.

Return

Returns true on success or false on failure.
