The foreach Loop

The foreach loop is used to loop through arrays.
Syntax
foreach ($array as $value)
{
code to be executed;
}
For every loop iteration, the value of the current array element is assigned to $value (and the array pointer is moved by one) - so on the next loop iteration, you'll be looking at the next array value.
Example
The following example demonstrates a loop that will print the values of the given array:
< html >
< body >

< ?php
$x=array("one","two","three");
foreach ($x as $value)
{
echo $value . "
";
}
? >

< /body >
< /html >
Output:
one
two
three


The real power of PHP comes from its functions.
In PHP, there are more than 700 built-in functions.
