ob_start -- Turn on output buffering


void ob_start(void);

This function will turn output buffering on. While output buffering is active no output is sent from the script, instead the output is stored in an internal buffer.

The contents of this internal buffer may be copied into a string variable using ob_get_contents(). To output what is stored in the internal buffer, use ob_end_flush(). Alternatively, ob_end_clean() will silently discard the buffer contents.
