Using control structures such as conditionals and loops in PHP scripts Mocktest

The while loop in PHP executes a block of code repeatedly as long as a specified condition is true.

The else statement in PHP is used to execute a block of code if the preceding if condition is false.

The switch statement in PHP is used to evaluate an expression against multiple possible cases.

The given code snippet uses a while loop to print numbers from 1 to 5. The loop condition is $x <= 5, and within the loop, $x is incremented by 1 in each iteration, and the value of $x is printed.

The if-else statement in PHP is used to execute a block of code if a specified condition is true, and another block of code if the condition is false.

The output of the code will be Hello because the condition $x > 3 is true, so the code block inside the if statement will be executed, resulting in the output Hello.

The do-while loop in PHP guarantees that the code block will be executed at least once, even if the condition is false.

The output of the code will be The number is: 5. Even though the condition $x <= 3 is false, the code block inside the do-while loop will be executed at least once before the condition is checked, so the value of $x will be printed once.

The foreach loop in PHP is typically used for iterating over the elements of an array.

The given code snippet uses a foreach loop to iterate over the elements of the $colors array and prints each element preceded by the text "Color:". Therefore, the output will be "Color: Red", "Color: Green", and "Color: Blue" on separate lines.
