The mb_detect_encoding() is an inbuilt function in PHP that is used to detect the encoding of the string.
Syntax:
string|false mb_detect_encoding(
string $string,
array|string|null $encodings = null,
bool $strict = false
)
Parameters: This function accepts three parameters that are described below.
- $string: The string for which the encoding needs to be detected.
- $encoding: A comma-separated list of encodings to be checked. If not specified, a list of popular encodings is used.
- $strict: A boolean value indicating whether to use strict detection or not. If set to “true”, only encodings that are super-sets of the input string’s encoding are returned.
Return Values: This function returns detecting encoding of the input string, if no encoded is detected, it will return “false”.
Example 1: The following program demonstrates the mb_detect_encoding() function.
PHP
<?php $string = "Hello world!"; $encoding = mb_detect_encoding($string); echo "The string '$string' is encoded in '$encoding'."; ?> |
Output:
The string 'Hello world!' is encoded in 'ASCII'.
Example 2: The following program demonstrates the mb_detect_encoding() function.
PHP
<?php $string = "This is an English sentence."; $encoding = mb_detect_encoding($string); if ($encoding === 'UTF-8') { echo "The string '$string' is encoded in UTF-8."; } else { echo "The string '$string' is not encoded in UTF-8."; } ?> |
Output:
