In the following example, the element is not deleted but empty string is stored in it..

Example:

<?php

$motorcycle[0] = "suzuki";
$motorcycle[1] = "ktm";
$motorcycle[2] = "honda"; 

$motorcycle[1] = "";

for ($index = 0; $index< count($motorcycle); $index++) {
echo $motorcycle[$index], "<br />";

}

?>

Save this file as removing-elements-from-array.php.

If you want to delete array from array, use the function unset().

unset ($value [1]);

Example 2:

<?php

$motorcycle[0] = "suzuki";
$motorcycle[1] = "ktm";
$motorcycle[2] = "honda"; 

unset($motorcycle[1]);

for ($index = 0; $index < count($motorcycle); $index++) {
echo $motorcycle[$index], "<br />";
}


?>

Explanation: if you now try to display an element that was removed you'll get a warning.

Result:

suzuki
