Control structures

Control structures in PHP are constructs that allow you to control the flow of your PHP code based on conditions or loops. They determine which code blocks are executed and how many times they are executed. PHP provides several control structures, including:

Here's a definition, example, and clarification for some common PHP operators:


Conditional Statements


$age = 25;
if ($age < 18) {
    echo "You are a minor.";
} elseif ($age >= 18 && $age < 65) {
    echo "You are an adult.";
} else {
    echo "You are a senior citizen.";
}
 

Loops


for ($i = 1; $i <= 5; $i++) {
    echo "Iteration $i
"; }

Branching Statements


$numbers = [1, 2, 3, 4, 5];
foreach ($numbers as $number) {
    if ($number == 3) {
        break; // Stops the loop when $number is 3
    }
    echo $number . "<br>";
}
 

Function and Method Calls


function greet($name) {
    echo "Hello, $name!"; }
greet("John"); //Call the function to greet John
 

These control structures are essential for controlling the flow of your PHP programs, making decisions, and iterating through data structures. They allow you to create more dynamic and responsive applications.
