Question

I have a script which checks the variable $hello to see if it contains “pink”, “blue” and “red”. For each variable it contains, some text is added to the string $finalstring.

Is there a simpler way to do this?

$hello = "pink*blue*red*orange";
$finalstring = "";

if (strpos($hello, "pink") == true) {
    $finalstring .= "_pink";
}

if (strpos($hello, "blue") == true) {
    $finalstring .= "_blue";
}

if (strpos($hello, "red") == true) {
    $finalstring .= "_red";
}

echo $finalstring; // output: _pink_blue_red

Answer 1

$finalstring = '';

$items = array('pink', 'blue', 'red');
foreach($items as $item)
{
   if(strpos($hello, $item) !== false)
   {
       $finalstring .= '_' . $item;
   }
}
