Loop is used whenever you want a code to run over and over again in row. We use Loop instead of adding almost same codes many times.
Loop Statements :
Loop continues as long as the condition is true – while
Loop continues a code once and repeats loop until specified condition is true – do..while
Loop continues for a number of time – for
Loop continues block of code for each element in an array – foreach
While Loop :
<!DOCTYPE html>
<html>
<body>
<?php
$x = 10;
while($x <= 20) {
echo "The number is: $x <br>";
$x++;
}
?>
</body>
</html>
Output :
do..while Loop :
<!DOCTYPE html>
<html>
<body>
<?php
$x = 1;
do {
echo "The number is: $x <br>";
$x++;
} while ($x <= 10);
?>
</body>
</html>
Output :
for Loop :
<!DOCTYPE html>
<html>
<body>
<?php
for ($a = 0; $a <= 10; $a++) {
echo "code-projects.org <br>";
}
?>
</body>
</html>
Output :
foreach Loop :
<!DOCTYPE html>
<html>
<body>
<?php
$lang = array("php", "python", "c++", "c#");
foreach ($lang as $value) {
echo "$value <br>";
}
?>
</body>
</html>
