Question

I have a question about arrays and foreach.

If i have an array like this:

$test_arr = array();
$test_arr['name1'] = "an example sentence";
$test_arr['anything'] = "dsfasfasgsdfg";
$test_arr['code'] = "4334refwewe";
$test_arr['empty1'] = "";
$test_arr['3242'] = "";

how can I do a foreach and “pick” only the ones that have values? (in my array example, would only take the first 3 ones, name1, anything and code).

I tried with

foreach ($test_arr as $test) {
  if (strlen($test >= 1)) {
    echo $test . "<br>";
  }
}

but it doesn’t work. Without the “if” condition it works, but empty array values are taken into consideration and I don’t want that (because I need to do a <br> after each value and I don’t want a <br> if there is no value)

Sorry if I don’t explain myself very well, I hope you understand my point. Shouldn’t be too difficult I guess..

Thanks for your help !

Answer 1

Maybe will work

foreach ($test_arr as $test) {
  if (strlen($test)!=="") {
    echo $test . "<br>";
  }
}

Your solution with corrected syntax:

foreach ($test_arr as $test) {
  if (strlen($test)>=1) {
    echo $test . "<br>";
  }
}
