Question

I have this string:

$array= 'orange, fruit, apple juice'

I want to count the single-word substrings in the string (orange/fruit)

I have tried

//Explode string at commas
$explode_tags = explode(",", $array);

//Check if space exists in substrings
foreach ($explode_tags as $explode_tag) {
  if (strstr(trim($explode_tag), ' ') == false) { 
  ...
  }
}   

Now I can’t figure out how to count the substrings only when the above IF statement comes false.

Answer 1

How about:

//Explode string at commas
$explode_tags = explode(",", $array);

$count = 0;
//Check if space exists in substrings
foreach ($explode_tags as $explode_tag) {
      if (strpos(trim($explode_tag), ' ') == false) { //strpos better for checking existance
          $count++;
      }
}

//Do something with $count
