php built in counter for what iteration foreach loop is currently in
foreach, indexing, iterator, php
Solution
Answer
As far as I know there is no build in numeric counter in a `foreach` loop in PHP.
So you need your own counter variable. Your example code looks quite good to do that.
$index = 0;
foreach($array as $key => $val) {
$index++;
}
By the way, `$index++;` is fine.
Example
Here is an example illustrating which variable stores which value.
$array = array(
"first" => 100,
"secnd" => 200,
"third" => 300,
);
$index = 0;
foreach($array as $key => $val) {
echo "index: " . $index . ", ";
echo "key: " . $key . ", ";
echo "value: " . $val . "\n";
$index++;
}
The output will be that.
index: 0, key: first, value: 100
index: 1, key: secnd, value: 200
index: 2, key: third, value: 300
Current-Function
I think you misunderstood `current($array)`. It gives you the value pointed by an internal array pointer, which can be moved using `next($array)`, `prev($array)` and `end($array)`.
Take a look at the manual to make thinks clear.
Problem
I have an associative array. Two dimensions which I am iterating through like this ``` foreach ( $order_information as $sector_index => $sector_value ){ echo 'sector : ' . current($order_information) ; echo '<br>'; foreach ( $sector_value as $line_index => $line_value ){ } } ``` The `current()` is an attempt to get the iteration the loop is in. It seems like this should give me that. However, elsewhere on that page there is the suggestions that you just do like ``` $index = 0 foreach ( $array as $key => $val ) { echo $index; $index++; } ``` I wonder if I am using current incorrectly, as `echo 'sector : ' . current($order_information);` just prints `sector : Array` Is $index++ bad syntax? Is there a better way to do this?
