I am receiving the following error in WordPress :
Deprecated: Function create_function() is deprecated in /var/www/html/myfile-4.php on line 42
My PHP code is the specified location above is as follows :
$callback = create_function('$arg', 'echo "Hello, $arg!";'); $callback('Mrinmoy');
I will be extremely grateful if someone would help me resolve this error.
Thank you in advance.
Deprecated PHP function
The PHP function
create_function()
is deprecated. This means that it is no longer supported by the latest versions of PHP. If you are usingcreate_function()
in your code, you will need to update it to use a different function.Anonymous functions
One way to update your code is to use an anonymous function. Anonymous functions are a type of function that does not have a name. They are often used in situations where you only need to use a function once.
Example
The following code shows how to update the
create_function()
function to use an anonymous function:$callback = function ($arg) {
echo “Hello, $arg!”;
};
$callback(‘Mrinmoy’);
By replacing the deprecated
create_function()
with an anonymous function, you can achieve the same functionality without triggering the deprecated function error.
