How to call a function from a string stored in a variable?
dynamic-function, php
Solution
`$functionName()` or `call_user_func($functionName)`
If you need to provide parameters stored in another variable (in the form of array), use array unpacking operator:
$function_name = 'trim';
$parameters = ['aaabbb','b'];
echo $function_name(...$parameters); // aaa
To dynamically create an object and call its method use
$class = 'DateTime';
$method = 'format';
echo (new $class)->$method('d-m-Y');
or to call a static method
$class = 'DateTime';
$static = 'createFromFormat';
$date = $class::$static('d-m-Y', '17-08-2023');
Problem
I need to be able to call a function, but the function name is stored in a variable, is this possible? e.g: ``` function foo () { //code here } function bar () { //code here } $functionName = "foo"; // I need to call the function based on what is $functionName ```
