Learn About Php Loops	Aprender sobre los bucles de php

Los bucles son bloques de código que se ejecutan un número específico de veces. El uso de bucles reduce el número de líneas de código.

PHP trabaja con 4 tipos diferentes de bucles:

• Mientras bucle
• Hacer ... mientras bucle
• En bucle
• Bucle foreach

Mientras bucle

El while bucle continúa excecute siempre que la condición especificada es verdadera.

`php

Example: 
 ```php 
 <?php 
  $x = 1; 
   while($x <= 3) 
   { 
     echo "x=$x "; 
     $x++; 
   } 
 ?> 

Output: 
x=1 x=2 x=3 

Do...while loop

In the do...while loop the block of code is executed before the condition is checked.

<?php 
   do { 
     execute code; 
   } while (condition); 
?> 

Example:

<?php 
$x= 1; 
   do { 
     echo "x=$x "; 
     $x++; 
   } while ($x < 5); 
?> 

Output: 
x=1 x=2 x=3 x=4 

For loop

The for loop is used when the number of times the block is to be executed is known in advance.

<?php 
   for (variable initialisation; test condition; increment) 
   { 
     execute code; 
   } 
?> 

Example:

<?php 
  for ($x=1 ; $x <= 4 ; $x++) 
  { 
    echo "x= $x "; 
  } 
?> 

Output: 
x=1 x=2 x=3 x=4 

Foreach loop

The foreach loop helps in traversing through arrays.

<?php 
  foreach ($array as $value) 
  { 
    executable code; 
  } 
?> 

Example:

<?php 
$numbers= array("One", "Two", "Three"); 
 foreach ($numbers as $value) 
 { 
   echo "$value "; 
 } 
?> 

Output: 
One Two Three
