Sanitize array or CSV string to array of values, optionally sanitized by given method
If given a string, delimiter may be pipe ("|"), or comma (","), unless overridden with the delimiter
or delimiters
options.
Usage
// basic usage
$array = $sanitizer->array($value);
// usage with all arguments
$array = $sanitizer->array($value, $sanitizer = null, array $options = []);

- if an unknown $sanitizer method is given
Hooking $sanitizer->array(…)
You can add your own hook events that are executed either before or after the $sanitizer
method is executed. Examples of both are included below. A good place for hook code such as this is in your /site/ready.php file.
Hooking before
The 'before' hooks are called immediately before each $sanitizer
method call is executed. This type of hook is especially useful for modifying arguments before they are sent to the method.
$this->addHookBefore('Sanitizer::array', function(HookEvent $event) {
// Get the object the event occurred on, if needed
$sanitizer = $event->object;
// Get values of arguments sent to hook (and optionally modify them)
$value = $event->arguments(0);
$sanitizer = $event->arguments(1);
$options = $event->arguments(2);
/* Your code here, perhaps modifying arguments */
// Populate back arguments (if you have modified them)
$event->arguments(0, $value);
$event->arguments(1, $sanitizer);
$event->arguments(2, $options);
});
Hooking after
The 'after' hooks are called immediately after each $sanitizer
method call is executed. This type of hook is especially useful for modifying the value that was returned by the method call.
$this->addHookAfter('Sanitizer::array', function(HookEvent $event) {
// Get the object the event occurred on, if needed
$sanitizer = $event->object;
// An 'after' hook can retrieve and/or modify the return value
$return = $event->return;
// Get values of arguments sent to hook (if needed)
$value = $event->arguments(0);
$sanitizer = $event->arguments(1);
$options = $event->arguments(2);
/* Your code here, perhaps modifying the return value */
// Populate back return value, if you have modified it
$event->return = $return;
});
