輸出緩衝區處理函數的作用有點類似C的堆棧，臨時放入一個儲存空間中，對內容進行處理。
輸出緩衝區函數有：
執行個體如下：
<?php define('APP_ROOT', dirname(__FILE__)); $file = '/templates/html/error_config.html'; ob_start(); include(APP_ROOT.$file); ob_end_flush(); //$contents = ob_get_contents(); 這樣可以將輸出儲存，可以作進一步處理 //ob_end_clean(); //echo $contents; ?>
<?php echo"<?xml version=\"1.0\" encoding=\"utf-8\">"; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta http-equiv="Content-Script-Type" content="text/javascript" /> <meta http-equiv="Content-Style-Type" content="text/css" /> <title>Error</title> </head> <body onload="doRedirect()"> <h1>Error</h1> <div style="position:absolute;top:150px;text-align:center;width:95%;"> <p style="margin:12pt;"><strong>config.php</strong> does not exist or is not readable by the webserver in the directory.</p> <p style="margin:12pt;"><?php echo CommonFunctions::$PSI_VERSION_STRING ?></p> </div> </body> </html>
輸出結果如下：
config.php does not exist or is not readable by the webserver in the phpsysinfo directory.
