PHP implements the method of subtracting two arrays, array subtraction

The example in this article describes the technique of php implementing the subtraction operation of two arrays. Share it with everyone for your reference. The details are as follows:

This code passes in two arrays A and B and returns the result of A-B, that is, selecting the elements that exist in A but not in B

<&#63;php
function RestaDeArrays($vectorA,$vectorB)
{
  $cantA=count($vectorA);
  $cantB=count($vectorB);
  $No_saca=0;
  for($i=0;$i<$cantA;$i++)
  {
    for($j=0;$j<$cantB;$j++)
    {
     if($vectorA[$i]==$vectorB[$j])
     $No_saca=1;
    }
   if($No_saca==0)
   $nuevo_array[]=$vectorA[$i];
   else
   $No_saca=0;
   }
   return $nuevo_array;
}
&#63;>

I hope this article will be helpful to everyone’s PHP programming design.
