How can a space be inserted after each value found in PHP?

To insert a space after each value found in PHP, you can use the implode function to join the array values with a space as the delimiter. This will create a new string with spaces between each value.

```php
$values = array("apple", "banana", "orange");
$spacedValues = implode(" ", $values);
echo $spacedValues;
```

This code snippet creates an array of values, joins them with a space delimiter using the implode function, and then echoes out the result with spaces between each value.
