PHP Loops: For, While, Do-While & Foreach Guide

In PHP, there are several common ways to loop:

1. For loop: Used to repeatedly execute a code block a specified number of times.

for ($i = 0; $i < 10; $i++) {
   echo $i;
}

1. While loop: the code block is repeated as long as the given condition is true.

$i = 0;
while ($i < 10) {
   echo $i;
   $i++;
}

1. Do-while loop: execute a code block, then check the condition, and repeat the code block as long as the condition is true.

$i = 0;
do {
   echo $i;
   $i++;
} while ($i < 10);

1. foreach loop: used to iterate through each element in an array.

$fruits = array("apple", "banana", "orange");
foreach ($fruits as $fruit) {
   echo $fruit;
}

1. A foreach loop can iterate through the keys and values of an associative array.

$person = array("name" => "John", "age" => 30);
foreach ($person as $key => $value) {
   echo $key . ": " . $value;
}

These are commonly used looping methods in PHP, and you can choose the appropriate one based on your specific needs to achieve the desired functionality.
