PHP Looping
Very often when you write code, you want the same block of code to run a number of times. You can use looping statements in your code to perform this.
In PHP we have the following looping statements:
while - loops through a block of code if and as long as a specified condition is true.
do...while - loops through a block of code once, and then repeats the loop as long as a special condition is true.
for - loops through a block of code a specified number of times.
foreach - loops through a block of code for each element in an array.
