To find an element in an array of pairs:

Use the [array->find] method with the value of the first element of the pairs that should be returned from the array.

The following example shows an array of pairs returned from the tag, each of which has a first element of 'John Doe'.

Code

var( People_Array = array('John Doe' = 'Person One',
                          'Jane Doe' = 'Person Two', 
                          'Joe Surname' = 'Person Three', 
                          'John Doe' = 'Person Four') )

$People_Array->find('John Doe')

Result

array((John Doe = Person One), (John Doe = Person Four))
