Loops in PHP are used to repeatedly execute a block of code until a certain condition is met. There are four types of loops in PHP: while, do-while, for, and foreach.
1. while loop: The while loop executes a block of code as long as a specified condition is true.
“`php
while (condition) {
// code to be executed
}
“`
2. do-while loop: The do-while loop is similar to the while loop, but it will always execute the code block at least once, even if the condition is false.
“`php
do {
// code to be executed
} while (condition);
“`
3. for loop: The for loop is used when you know the number of times you want to execute a block of code.
“`php
for (initialization; condition; increment) {
// code to be executed
}
“`
4. foreach loop: The foreach loop is used to iterate over arrays and objects.
“`php
foreach ($array as $value) {
// code to be executed
}
“`
In addition to these basic loops, PHP also provides control structures like break and continue to control the execution flow within a loop. Break is used to exit the current loop, while continue is used to skip the rest of the current iteration and move to the next one.
