What Are Different Types Of Loops With Explanation In PHP

• Execute the same block of code again to again, as long as certain condition is met. instead of adding several almost equal code-lines in a script, we can use loops.

• while – loops through a block of code as long as the condition specified evaluates to true
• do...while - loops through a block of code once, and then repeats the loop as long as the specified condition is true
• for - loops through a block of code a specified number of times
• foreach - loops through a block of code for each element in an array

• The while loop executes a block of code as long as the specified condition is true.
• Example:

       while (condition is true) {
      code to be executed;
   }

•  it will then check the condition, and repeat the loop while the specified condition is true.
• Example:
•  do {
    code to be executed;
  } while (condition is true);
   

• It is typically used to execute a block of code for certain number of times.
• Example:

             for(initialization; condition; increment){
    // Code to be executed
    }
 

• The foreach loop works only on arrays, and is used to loop through each key/value pair in an array.
• Example:

foreach ($array as $value) {
  code to be executed;
}
