(PHP 4, PHP 5)
ob_get_contents — Return the contents of the output buffer
Gets the contents of the output buffer without clearing it.
This will return the contents of the output buffer or FALSE, if output buffering isn't active.
Example #1 A simple ob_get_contents() example
<?php
ob_start();
echo "Hello ";
$out1 = ob_get_contents();
echo "World";
$out2 = ob_get_contents();
ob_end_clean();
var_dump($out1, $out2);
?>
上例将输出：
string(6) "Hello " string(11) "Hello World"
