How to check for multiple values in array?

Question

I am trying to check for values in array and if value found increment it. I've tried to do it as shown in code below, but not successful.

$productdas=array("DAS","DayEnd","DAAS");
if (strpos(serialize($row['pirority']),"P1")!==false &&
   strpos(serialize($row['product']),'$productdas')!==false) 
       { 
         $dasp1++; 
       }

I'll be grateful for any help.

Regards.

What does $row['pirority'] contain and what is the expected result? — Amal

You would need to write an strpos() variant that accepts an array as $needle; for example:

function strpos_array($haystack, array $needles)
{
    foreach ($needles as $needle) {
        if (($pos = strpos($haystack, $needle)) !== false) {
            return $pos;
        }
    }
    return false;
}

if (strpos_array(serialize($row['product']), $productdas)!==false) { ... }

It's also possible to implement this using preg_match().

I'm assuming you're trying to search the given string for any of the values in $productas array and find the number of total occurrences. This can be done with substr_count():

$productdas = array("DAS","DayEnd","DAAS");
$count = 0;

foreach ($productdas as $needle) {
    $count += substr_count($row['pirority'], $needle);
}

echo $count;

If $row['pirority'] is DASfooDayEndDAAShelloDAS, then the count would be 4.
