PHP Loop

In PHP, loops are used to repeatedly execute a block of code based on a condition or for a specified number of iterations. PHP provides several types of loops to cater to different looping requirements. Here are the most commonly used loop structures in PHP:

while Loop:

The while loop executes a block of code repeatedly as long as a specified condition evaluates to true. The code block is executed before checking the condition.

while (condition) {
    // Code to execute
}

do...while Loop:

The do...while the loop is similar to the while loop, but the condition is checked after the code block is executed. This guarantees that the code block executes at least once, even if the condition is initially false.

do {
    // Code to execute
} while (condition);

for Loop:

The for loop executes a block of code for a specified number of iterations. It consists of an initialization, condition check, and an increment/decrement statement.

for (initialization; condition; increment/decrement) {
    // Code to execute
}

foreach Loop:

The foreach loop is specifically designed for iterating over arrays and objects. It automatically traverses each element of the array or properties of the object.

foreach ($array as $value) {
    // Code to execute
}

break and continue Statements:

The break statement is used to exit a loop prematurely, while the continue statement skips the remaining code in the loop and moves to the next iteration.

while (condition) {
    if (condition) {
        break;    // Exit the loop
    }

    if (condition) {
        continue; // Skip to the next iteration
    }

    // Code to execute
}

Loops are essential for repetitive tasks and iterating over arrays, database records, or any collection of data. They provide flexibility and efficiency in handling such scenarios.
