Create a helpers.php file in your app folder and load it up with composer:
"autoload": {
"classmap": [
...
],
"psr-4": {
"App": "app/"
},
"files": [
"app/helpers.php" // <---- ADD THIS
]
},
After adding that to your composer.json file, run the following command:
composer dump-autoload
"autoload": {
"files": [
"app/helpers.php"
],
"classmap": [
"database/seeds",
"database/factories"
],
"psr-4": {
"App": "app/"
}
},
$callback = function ($value) {
return (is_numeric($value)) ? $value * 2 : 0;
};
$result = with(5, $callback);
// 10
$result = with(null, $callback);
// 0
$result = with(5, null);
// 5
