streamWrapper::stream_read

(PHP 4 >= 4.3.2, PHP 5, PHP 7)

Read from stream

public string streamWrapper::stream_read ( int $count )

This method is called in response to fread() and fgets().

Note:

Remember to update the read/write position of the stream (by the number of bytes that were successfully read).

Parameters:

count

How many bytes of data from the current position should be returned.

Returns:

If there are less than count bytes available, return as many as are available. If no more data is available, return either FALSE or an empty string.

Exception:

Emits E_WARNING if call to this method fails (i.e. not implemented).

Note:

If the return value is longer then count an E_WARNING error will be emitted, and excess data will be lost.

Notes:

streamWrapper::stream_eof() is called directly after calling streamWrapper::stream_read() to check if EOF has been reached. If not implemented, EOF is assumed.
