62.3.3 Loops
Loops are used to repetitively execute a block of code until or when a specific condition is true. Loops
are used to perform the same task again and again so that we do not have to write several, almost equal
statements.
In PHP, loop statements such as while, do….while, and for are used differently depending on the
condition.
Example:
//while statement.
Output of above code: 1 2 3 4 5
//do.....while statement
Output: 2 3 4 5 6
//for loop
Syntax:
for (init; condition; increment){
code to be executed;
}
