title: PHP: What is the searching algorithm implemented in array_search()?
body: <p>I have an array of items on which I would like to apply search function. I am considering sorting the array and simply applying binary search for now as it need not be too complex, however if I run into problems I'll try other methods.</p>
  
  <p>My question is; what is the search algorithm used in the array_search()? If it is indeed binary search I can use that.</p>
