How to use the for loop in PHP?

In PHP, the for loop is used for executing a set of statements a fixed number of times. The basic syntax for the for loop is as follows:

1
2
3

for (initialization; condition; increment/decrement) {
  // code to be executed;
}

The three parts of the for loop are as follows:

• initialization: This is the first part of the loop, where you can initialize a variable with a starting value. This part is executed only once, before the loop starts.
• condition: This is the second part of the loop, where you can define the condition that must be met for the loop to continue running. The loop will continue running as long as the condition is true.
• increment/decrement: This is the third part of the loop, where you can specify how the variable should change after each iteration of the loop. You can increment the variable (i++) or decrement the variable (i--) depending on your needs.

Here is an example of using the for loop in PHP to print numbers from 1 to 10:

1
2
3

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

In this example, the variable $i is initialized to 1, and the loop will continue running as long as $i is less than or equal to 10. After each iteration of the loop, the variable $i is incremented by 1. The echo statement is used to output the value of $i to the screen, followed by a line break using the HTML <br> tag.

Output:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

1
2
3
4
5
6
7
8
9
10

You can modify the for loop to suit your specific needs by changing the initialization, condition, and increment/decrement values.
