Question

What I want to do is following.

Lets say we have array like that

$arr=array();
$arr[1]['test1']="something";
$arr[1]['test2']="something else"

…

$arr[2]['test1']="blah blah";
$arr[2]['test2']="foo bar"

…

I want to echo them one by one like that

something   something else ... <all elements of $arr[1]>

blah blah  foo bar         ... <all elements of $arr[2]>

BUT!

if($arr[1]['test1']=="something")
don't echo elements of $arr[1] at all

Is that possible by new array creation in which $arr[1] doesn’t exist at all? Or during echo?

Answer 1

Maybe this should do the trick:

// Iterate and show the words
foreach ($arr as $words) {
    if (in_array("something", $words))
        continue;

    echo join(' ', $words) . '<br />';
}

The continue call will jump to the next iteration, so it will skip the array if it contains the “something” element
