Sanitize array or CSV string to array of strings

If string specified, string delimiter may be pipe ("|"), or comma (","), unless overridden with the 'delimiter' or 'delimiters' option.

Usage

// basic usage
$array = $sanitizer->array($value);

// usage with all arguments
$array = $sanitizer->array($value, string $sanitizer = null, array $options = []);

Arguments

NameType(s)Description
$valuearray or string or mixed

Accepts an array or CSV string. If given something else, it becomes first item in array.

$sanitizer (optional)string

Optional Sanitizer method to apply to items in the array (default=null, aka none).

$options (optional)array

Optional modifications to default behavior: maxItems (int): Maximum items allowed in array (default=0, which means no limit)
The following options are only used if the provided $value is a string:

  • delimiter (string): Single delimiter to use to identify CSV strings. Overrides the 'delimiters' option when specified (default=null)
  • delimiters (array): Delimiters to identify CSV strings. First found delimiter will be used, default=array("|", ",")
  • enclosure (string): Enclosure to use for CSV strings (default=double quote, i.e. ")

Return value

array

Exceptions

Method can throw exceptions on error:

  • WireException - 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->array(…) 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->array(…) 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->array(…) 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;
});
