Control Structures in PHP

Control structures in PHP are used to control the flow of a program, such as if statements and loops.

For example, an if statement can be used to check if a certain condition is true and execute a certain statement if it is:

$x = 5;

if ($x == 5) {
    echo "x is equal to 5";
}

In this example, the variable $x is declared and assigned the value 5. The if statement then checks if $x is equal to 5, and if it is, the statement “x is equal to 5” is echoed to the screen.

A loop, such as a for loop, can be used to execute a set of instructions repeatedly until a certain condition is met:

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

In this example, the for loop is used to loop 10 times and echo the value of $i at each iteration. The loop will start at 0 and increment $i by 1 each time until it reaches 10. The output of this loop will be 0 1 2 3 4 5 6 7 8 9.
