PHP Loop

loop in PHP is used to execute a statement or a block of statements, multiple times until and unless a specific condition is met. This helps the user to save both time and effort of writing the same code multiple times.

• 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.
• 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.

<?php  
  
// code to illustrate for loop 
for ($num = 1; $num <= 10; $num += 2) { 
    echo "$num \n"; 
}  
  
?>

initialization – Initialize the loop counter value. The initial value of the for loop is done only once. This parameter is optional.

condition – Evaluate each iteration value. The loop continuously executes until the condition is false. If TRUE, the loop execution continues, otherwise the execution of the loop ends.

Increment/decrement – It increments or decrements the value of the variable.
