PHP loops

In this tutorial I will show you all loops in PHP and their usage with code examples.

Step 1 - PHP loops

PHP loops

PHP loops are control structures and you can use them the execute a code block more times. It means you don't have to copy and paste your code many times in the file just use a right loop statement.

A basic example:

Code: 
   echo " 1 ";
   echo " 2 ";
   echo " 3 ";
   echo " 4 ";
   echo " 5 ";
   echo " 6 ";
   echo " 7 ";
   echo " 8 ";
   echo " 9 ";

And with a for loop it looks like this:

Code: 
for ($i=1;$i<=9;$i++){
   echo " $i ";
}
 
PHP F1

And the output of both code is similar:

Output: 
 1  2  3  4  5  6  7  8  9PHP F1

As you can see the sollution with loop is much better. It is shorter, more easy to understand. Besides this in most cases you don't know during the coding how many times the code block needs to be executed.

After this short example let's see what kind of loop statements are in PHP.

while loop
do ... while loop
for loop
foreach loop

Besides this you can control your loops with:

break
continue

In the next steps I will show you all of them.
