ob_get_clean — Get current buffer contents and delete current output buffer
Gets the current buffer contents and delete current output buffer.
ob_get_clean() essentially executes both ob_get_contents() and ob_end_clean().
Returns the contents of the output buffer and end output buffering. If output buffering isn't active then FALSE is returned.
Beispiel #1 A simple ob_get_clean() example
<?php
ob_start();
echo "Hello World";
$out = ob_get_clean();
$out = strtolower($out);
var_dump($out);
?>
Das oben gezeigte Beispiel erzeugt folgende Ausgabe:
string(11) "hello world"
Hi
Warning, this command isn't exactly like ob_get_contents() and ob_end_clean() successively. Sometimes you will have to do these two commands manually.
Today I lost 2 hours to localize that problem and to find the solution -_-'
See you
Maybe it can be useful
$__ob_stack=array();
function ob_break() {
global $__ob_stack;
while (ob_get_level()>0)
array_push($__ob_stack,ob_get_clean());
}
function ob_continue() {
global $__ob_stack;
while (count($__ob_stack)>0) {
ob_start();
echo array_pop($__ob_stack);
}
}
ob_start();
echo "1"; // now we write to "ob" buffer
ob_break();
echo "2"; // now we write to stdout
ob_continue();
echo "3"; // now we write again to "ob" buffer
$output=ob_get_clean();
echo $output;
// output is 213
If you're trying to capture the output from an included 3rd party script you don't seem to be capturing everything, the following might help:
function ob_end_clean_all()
{
$s = "";
do
{
$s = ob_get_contents() . $s;
} while(ob_end_clean());
return $s;
}
This function closes all nested output bufferings, therefore closing any buffers that the included script does not explicitly close. It's basically a ob_end_clean that sweeps together all the output buffers instead of just the innermost one.
Notice that the function beneath does not catch errors, so throw in an @ before those ob_* calls
Running PHP4 < 4.3.0, you can simply add the following to use the function anyway:
<?php
if (!function_exists("ob_get_clean")) {
function ob_get_clean() {
$ob_contents = ob_get_contents();
ob_end_clean();
return $ob_contents;
}
}
?>
