WireArray::implode() method

Combine all elements into a delimiter-separated string containing the given property from each item

Similar to PHP's implode() function.

Usage

// basic usage
$string = $wireArray->implode(string $delimiter);

// usage with all arguments
$string = $wireArray->implode(string $delimiter, $property = '', array $options = []);

Arguments

NameType(s)Description
delimiterstring

The delimiter to separate each item by (or the glue to tie them together). If not needed, this argument may be omitted and $property supplied first (also shifting $options to 2nd arg).

property (optional)string, callable

The property to retrieve from each item, or a function that returns the value to store. If a function/closure is provided it is given the $item (argument 1) and the $key (argument 2), and it should return the value (string) to use. If delimiter is omitted, this becomes the first argument.

options (optional)array

Optional options to modify the behavior:

  • skipEmpty (bool): Whether empty items should be skipped (default=true)
  • prepend (string): String to prepend to result. Ignored if result is blank.
  • append (string): String to append to result. Ignored if result is blank.
  • Please note that if delimiter is omitted, $options becomes the second argument.

Return value

“We were really happy to build our new portfolio website on ProcessWire! We wanted something that gave us plenty of control on the back-end, without any bloat on the front end - just a nice, easy to access API for all our content that left us free to design and build however we liked.” —Castus, web design agency in Sheffield, UK
