PHP ob_get_clean() Function

Last Updated : 18 Aug, 2023

The ob_get_clean() function is an in-built PHP function that is used to clean or delete the current output buffer. It's also used to get the output buffering again after cleaning the buffer. The ob_get_clean() function is the combination of both ob_get_contents() and ob_end_clean().

Syntax:

string|false ob_get_clean();

Parameters: It does not accept any parameter.

Return value: This function returns the contents of the output buffer and end output buffering. If output buffering is not active, then it returns false.

Example 1: Below is a simple example of ob_get_clean() functionality.

PHP

<?php

 // Create an output buffer
ob_start();

echo "Welcome to GeeksforGeeks";

$out = ob_get_clean();
$out = strtolower($out);

var_dump($out);
?>

Output:

string(24) "Welcome to GeeksforGeeks"

Example 2:

PHP

<?php

// Declare a class 
class GFG {
    public function GFG_Funcion() {
        $variable = array(
            "A" => "Welcome",
            "B" => "GeeksforGeeks",
            "C" => "Geeks"
        );

        foreach ($variable as $key => $value) {
            echo $key . " => " . $value;
            echo "<br/>";
        }
    }
}

ob_start();

// Creating an object of class GFG
$object = new GFG();

// Calling function
$object -> GFG_Funcion();

$saved_ob_level = ob_get_level();

$start_ob_level="";

while (ob_get_level() > $start_ob_level) {
    ob_end_flush();
}

// Now, it is the final output buffer
$content = ob_get_clean();

?>

Output:

A => Welcome
B => GeeksforGeeks
C => Geeks
