PHP mb_http_output() Function - Coding

The mb_http_output() function is an inbuilt function in PHP that is used to set and retrieve the character encoding. This function allows you to specify a character encoding for HTTP response.

Syntax:

mb_http_output($encoding )

Parameters: This function accepts only one parameter which is described below.

$encoding: This is the optional parameter that specifies the character encoding.

Return Value: This function returns the boolean value if the function successfully executes, it will return “true” otherwise it will return false. If the $encoding removes the function, it will be used by default encoding.

Program 1: The following program demonstrates the mb_http_output() function.

PHP

<?php 
  
// Get the current HTTP output character encoding 
$encoding = mb_http_output(); 
  
echo "Current HTTP output encoding: " . $encoding; 
  
?>

Output

Current HTTP output encoding: UTF-8

Program 2: The following program demonstrates the mb_http_output() function.

PHP

<?php 
  
$encoding = "UTF-8"; 
$condition = true; 
  
function custom_mb_http_output($encoding, $condition) { 
  
    // Validate the encoding parameter 
    if (!in_array($encoding, mb_list_encodings())) { 
        return false; // Invalid encoding 
    } 
  
    // Conditionally set the character encoding 
    // based on a condition 
    if ($condition) { 
        mb_http_output($encoding); 
        return true; // Encoding set successfully 
    } else { 
        return false; // Encoding not set 
    } 
} 
  
if (custom_mb_http_output($encoding, $condition)) { 
    echo "Character encoding set to $encoding for HTTP output."; 
} else { 
    echo "Failed to set character encoding for HTTP output."; 
} 
  
?>

Output:

Character encoding set to UTF-8 for HTTP output.
