PHP FOREACH Loop

FOREACH is used in PHP to loop over all elements of an array. The basic syntax of FOREACH is as follows:

FOREACH ($array_variable as $value)
{
  [code to execute]
}

or

FOREACH ($array_variable as $key => $value)
{
  [code to execute]
}

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

Let's look at an example. Assuming we have the following piece of code:

$array1 = array(1,2,3,4,5); FOREACH ($array1 as $abc) {   print "new value is " . $abc*10 . "<br>"; }

The output of the above code is:

new value is 10 new value is 20 new value is 30 new value is 40 new value is 50

The FOREACH loop above went through all 5 elements of array $array1, and each time prints out a statement containing 10x the array element value.
