title: How can you make a multidimensional array unique?
body: <p>I've got a multidimensional array setup like the following:</p>
  
  <pre><code>array(
    [0]=&gt;
    array(
      ["name"]=&gt; "Foo"
      ["slug"]=&gt; "Bar"
    )
    [1]=&gt;
    array(
      ["name"]=&gt; "Foo"
      ["slug"]=&gt; "Bar"
    )
    [2]=&gt;
    array(
      ["name"]=&gt; "Test 1"
      ["slug"]=&gt; "test-1"
    )
    [3]=&gt;
    array(
      ["name"]=&gt; "Test 2"
      ["slug"]=&gt; "test-2"
    )
    [4]=&gt;
    array(
      ["name"]=&gt; "Test 3"
      ["slug"]=&gt; "test-3"
    )
  )
  </code></pre>
  
  <p>What would be the best way to search through the area for duplicates  values in "name" and remove them, so that each value in the multidimensional array is unique?</p>
  
  <p>Thanks in advance!</p>
