ob_end_clean

(PHP 4, PHP 5)

ob_end_clean — Clean (erase) the output buffer and turn off output buffering

说明

bool ob_end_clean ( void )

This function discards the contents of the topmost output buffer and turns off this output buffering. If you want to further process the buffer's contents you have to call ob_get_contents() before ob_end_clean() as the buffer contents are discarded when ob_end_clean() is called.

返回值

如果成功则返回 TRUE,失败则返回 FALSE。 Reasons for failure are first that you called the function without an active buffer or that for some reason a buffer could not be deleted (possible for special buffer).

错误/异常

If the function fails it generates an E_NOTICE.

更新日志

版本 说明
4.2.0 The boolean return value was added.

范例

The following example shows an easy way to get rid of all output buffers:

Example#1 ob_end_clean() example

<?php
ob_start
();
echo 
'Text that won\'t get displayed.';
ob_end_clean();
?>
