don't fix list()+each() with foreach() ...
// things to do when your stuck:
echo '<pre>';
var_dump($elements);
print_r($elements);
foreach($elements as $e) {
var_dump($e);
print_r($e);
}
echo '</pre>';
// example 1
foreach($elements as $e) {
echo "value= ",$e,"<br />";
}
// example 2
foreach($elements as $key => $value) {
echo "value= ",$value,"<br />";
echo "key= ",$key,"<br />";
}
// example 3
reset($elements);
while(list(, $value) = each($elements)) {
echo "value = " . $value . "<br />";
}
// example 4
reset($elements);
while(list($key, $value) = each($elements)) {
echo "key = " . $key . "<br />";
echo "value = " . $value . "<br />";
}
