PHP for loop

The for loop used when number of iterations is known, means you know how many times you want to execute a block of code.


for(initialization; condition; increment/decrement){  
//execute the statement; 
initialization: Initialize the loop initial value.
condition: check the condition is true.
execute the statement;
increment/decrement: Increase/decrease the loop counter value

Example- 1

for ($i = 1; $i <= 10; $i++) {
    echo $i;
//output: 12345678910
