The problem is that by default $v1 and $v2 are not *references* to
the elements in the array you are looping through. Instead, they are
copies of the values, so changing them doesn't have any effect on the
original array. There are a couple ways around this:
1) if you're using php 5, you can make the value variable in the
foreach statement a reference by prefixing it with "&":
foreach ($array as &$value) {
$value = htmlentities($value);
}
2) or you can use the array keys to reassign the value back to the
original place in the array:
foreach ($array as $key => $value) {
$array[$key] = htmlentities($value);
}
As Cliff said, you can find the full details here:
