Is it possible to find the foreach
index?
in a for
loop as follows:
for ($i = 0; $i < 10; ++$i) {
echo $i . ' ';
}
$i
will give you the index.
Do I have to use the for
loop or is there some way to get the index in the foreach
loop?
foreach($array as $key=>$value) {
// do stuff
}
$key
is the index of each $array
element
You can put a hack in your foreach
, such as a field incremented on each run-through, which is exactly what the for
loop gives you in a numerically-indexed array. Such a field would be a pseudo-index that needs manual management (increments, etc).
A foreach
will give you your index in the form of your $key
value, so such a hack shouldn't be necessary.
e.g., in a foreach
$index = 0;
foreach($data as $key=>$val) {
// Use $key as an index, or...
// ... manage the index this way..
echo "Index is $index\n";
$index++;
}
