two。 Php output cache is not open: echo,print-> server buffering-> browser buffering-> browser display

Ob_start (); / / enable ob caching

/ / ob cache is turned off by default in php5.2, and enabled by default in php5.3 version

/ / you can set the parameters of output_buffering in php.ini to determine whether ob cache is enabled by default.

/ / Off: disable PHP output cache On: open infinite output cache 4096: open output cache with the size of 4096Byte

Ob_get_contents (); / / get ob cache content

Ob_clean (); / / ob cache is empty and ob is not closed

Ob_end_clean (); / / ob cache is emptied and ob cache is turned off

Ob_end_flush (); / / flush the contents of the ob cache to the program cache while closing the ob cache
