What is the meaning of loop and how many type of loop in PHP

Looping and type of loop.........

Hi Balu,
If you want to execute a block of code a specified number of times, or while a specified condition is true.
In PHP, we have the following looping statements:
while - loops through a block of code while a specified condition is true
do...while - loops through a block of code once, and then repeats the loop as long as a specified 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
