PHP Loops
Loops are used to execute the same block of code again and again, as long as a certain condition is true.
1. While Loop
The while loop loops through a block of code as long as the specified condition is true.
$x = 1;
while($x <= 5) {
echo "The number is: $x <br>";
$x++;
}2. Do...While Loop
The do...while loop will always execute the block of code once, it will then check the condition, and repeat the loop while the specified condition is true.
$x = 1;
do {
echo "The number is: $x <br>";
$x++;
} while ($x <= 5);3. For Loop
The for loop is used when you know in advance how many times the script should run.
for ($x = 0; $x <= 10; $x++) {
echo "The number is: $x <br>";
}4. Foreach Loop
The foreach loop works only on arrays, and is used to loop through each key/value pair in an array.
$colors = array("red", "green", "blue", "yellow");
foreach ($colors as $value) {
echo "$value <br>";
}
