PHP foreach Loop instance foreach usage

FOREACH ($array _variable as $value)
{
[Code to execute]
}

Or

FOREACH ($array _variable as $key => $value)
{
[Code to execute]
}

In both cases, multiple [code executions] will be executed equal to the number of elements in the $ array_variable array.

Let's take a look at an example. Let's say we have the following code snippet:

$array 1 = array (1,2,3,4,5);
FOREACH ($array 1 as $ABC)
{
Print "New value is". $abc *10. "<br>";
}

Output results

New value is 10
New value is 20
New value is 30
New value is 40
New value is 50

The Foreach loop goes through the array $ array1 of all 5 elements, each time printing out a statement containing 10 times times the value of the array element.
The foreach action is to iterate through all the values of the current array and assign it to $var.

Let's look at a foreach. Instance of multidimensional data operation

  $s = array (array (1,2), array (3,4), Array (5,6));
 foreach ($s as $v => $_v)
  {
   foreach ($_v as $VC => $_vc)
&nbs p;  {
    echo $_vc[0], ' | '. $_vc[1], ' <br/> ';
   //print_r ($_VC);
   }
  }
