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 neveropen"; $out = ob_get_clean(); $out = strtolower($out); var_dump($out); ?> |
Output:
string(24) "Welcome to neveropen"
Example 2:
PHP
<?php // Declare a class class GFG { public function GFG_Funcion() { $variable = array( "A" => "Welcome", "B" => "neveropen", "C" => "Geeks" ); foreach ($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 => neveropen C => Geeks
