For loop in PHP is used to iterate through a section in an application. This is used frequently in many applications. Different requirements can be achieved like breaking the loop based on some condition by using break statement etc can be added. We will start with a basic loop and then move to adding different requirements to it. Here is the basic syntax for for loop.

for($i=1; $i<=10; $i++){
echo $i."<br>";
}


This will list from number one to ten. Now we will try with a break statement in side the for loop.

for($i=1; $i<=10; $i++){
if($i > 5){break;}
echo $i."<br>";
}

This will list from 1 to 5 only. The If condition inside the for loop will exit the loop when the value of $i exceeds 5 ( that is when it equals to 6)

While handling PHP Arrays foreach function is required to display the elements of an array. Once the foreach function is called the array pointer will reset to the first element of the array. So we need not call the reset() again( Reset() rewinds array’s internal pointer to the first element. ). Here is an example of the foreach code.

$i = array (10, 12, 13, 25);
foreach ($i as $v) {
print "Present value of \$i: $v <br> ";
}

This will list all the values of the array from starting to end.
