PHP foreach/else issue

Question

foreach($cases['rows'] as $i => $item) {
    foreach($array as $key => $val) {
        if($item['status'] == $key) {
            echo $val;
        }
    }
}

Right now this code functions, but if $item['status'] != $key it echoes nothing. I've tried to add an else statement after the if statement except it prints it tens of times.

How can I achieve this functionality? I want it to print $item['status'] if $item['status'] != $key

Help is appreciated.

Thanks.

you have to show more, because if it works for !=, it works for ==, it comes from somewhere else — t0mpl

Sounds like you might want to put the if statement outside the inner loop. — Kryten

So... This code works, but a version you're not showing us doesn't work? Can you maybe share the non-working version so we can help? — David

The way I understand the question you have two arrays:

An array containing different abbreviations and their full meaning.
Another multidimensional array containing arrays which again contain status-abbreviations.

To echo the full meaning instead of the abbreviations:

$abbreviations = array('NT' => 'Not taken',
                       'N/A' => 'Not available');

$data = array(array('status' => 'NT'),
              array('status' => 'N/A'));

foreach($data as $item) {
    if(array_key_exists($item['status'], $abbreviations)) {
        echo $abbreviations[$item['status']] . PHP_EOL;
    } else {
        echo $item['status'] . PHP_EOL;
    }
}

Result:

Not taken

Not available

Try this:

$test = null;
foreach($cases['rows'] as $i => $item) {
    foreach($array as $key => $val) {
        if($item['status'] == $key) {
            echo $val;
        }
        else {
            $test = $val;
        }
    }
}
if($test != null) {
    echo $test//Or whatever you want to display
}

This appends the last value in my array of key/values to the end of every row.

I changed the echo $test to echo $item['status'] and now it works fine EXCEPT it tacks on the key to the end of each row.

Without more info regarding the type of data in both arrays, I would suggest you to try:

!($item['status'] == $key) deny the correct statement
$item['status'] !== $key try also checking the same type (test this also with the equal statement to see if you get the results you expect)
