__toString()

__toString

(

)

{Reads all data from the stream into a string, from the beginning to end.This method MUST attempt to seek to the beginning of the stream before reading data and read the stream until the end is reached.Warning: This could attempt to load a large amount of data into memory.This method MUST NOT raise an exception in order to conform with PHP's string casting operations.
