title: Merge 2 Arrays Interchanging Index PHP
body: <p>Not sure if I described it properly in the title, but I'm looking to merge 2 arrays in php, although I don't want the new array to have the first array first and then the second array at the end, instead I want it to have the first item of the first array, first item of the second array, 2nd item of the first array, etc</p>
  
  <p>so essentially</p>
  
  <pre><code>Array 1
       A - 1
       A - 2
       A - 3
  
  Array 2
       B - 1
       B - 2
       B - 3
  </code></pre>
  
  <p>and after merging the two, the resulting array will be</p>
  
  <pre><code>Array Merged
       A - 1
       B - 1
       A - 2
       B - 2
       A - 3
       B - 3
  </code></pre>
  
  <p>In that order, can anyone help me out?</p>
