How can I remove duplicates in an object array in PHP?

arrays, php

Solution

Here's a simple test that at least should get you started. Your __toString method might need to be more elaborate to generate uniqueness for your instances of FanStruct

<?php

class FanStruct{
    public $date;
    public $userid;

    function __construct($date, $id){
        $this->date = $date;
        $this->userid = $id;
    }

    public function __toString()
    {
      return $this->date . $this->userid;
    }
}

$test = array(
  new FanStruct( 'today', 1 )
  ,new FanStruct( 'today', 1 )
  ,new FanStruct( 'tomorrow', 1 )
);

print_r( array_unique( $test ) );

?>

Problem

I have an object like this: ``` class FanStruct{ public $date; public $userid; function __construct($date, $id){ $this->date = $date; $this->userid = $id; } } ``` I have maximum of 30 of them in an array, and they are sorted by `$userid`. What is the best way to go though the array, and remove duplicate objects based on `$userid` (ignoring `$date`)?
