Question

Say I have the following array of strings:

$data_array = array("the dog is hairy", "cats like treats", "my mouse is tired");

I want to write a function that will extract an element from the array based on whether it contains another string.

For example, if the array element contains the string “dog” i want to return the string “the dog is hairy” for use elsewhere.

I tried using a foreach loop but it didn’t work:

foreach ($data_array as $sentence){
    if (stripos($sentence, "dog")){
        echo $sentence;
    }
}

What is the best way to go about this?

Answer 1

If you want to use stripos this is the code:

   $data_array = array("the dog is hairy", "cats like treats", "my mouse is tired");
   foreach($data_array as $value)
   {
      if (stripos($value, 'dog') !== FALSE)
         echo $value;
   }
