Loops execute a block of code a specified number of times, or while a specified condition is
Often when you write code, you want the same block of code to run over and over again in a row.
Instead of adding several almost equal lines in a script we can use loops to perform a task like
In PHP, we have the following looping statements:
The while loop executes a block of code while a condition is true.
The example below defines a loop that starts with i=1. The loop will continue to run as long as i
is less than, or equal to 5. i will increase by 1 each time the loop runs:
The do...while statement will always execute the block of code once, it will then check the
condition, and repeat the loop while the condition is true.
The example below defines a loop that starts with i=1. It will then increment i with 1, and write
some output. Then the condition is checked, and the loop will continue to run as long as i is
less than, or equal to 5:
The for loop and the foreach loop will be explained in the next chapter.
