Php multiple word search in a string

Question

I got lots of result and codes about search string. But all are search single word. I want to search multiple word and any of word match string will be display.

Example:

$string = "Apple is a big tech company!";
$search = 'Apple Logo';

Now I want if "Apple Logo" or "Apple" or "Logo" in string then it will return True else it will show False.

How I do that? I already tried lot of PHP codes. I also see ElasticSearch but I want something handy and easy to use.

if (stripos($string, $search) !== false) {
 echo "Found";
}

"I also see ElasticSearch but I want something handy and easy to use." - Where does the text you want to search come from? Database? Text file? Hard coded? Going from regex on a string to ElasticSearch is a pretty wide jump. — M. Eriksson

Actually, I'll use this function to search inside a multidimensional array.. so my one friend suggest me to use ElasticSearch.. But I don't want to use a third party tools. — I Am Stack

You don't show any multidimensional array which may be a different answer entirely. — AbraCadaver

yeah.. I didn't add it here.. because I want a simple answer.. I posted another question about this and didn't get a answer, that's why I posted this question more simple way. — I Am Stack

...and where do you get that multidimensional array from? Regardless if it is in a string or if it is in an array, it comes from somewhere at some point, right? Database? Text file? Hard coded? The answer depends on that as well since you already can search for the text if you have it in a database. — M. Eriksson

You can use an array of the words, replace them and check against the original:

if(str_ireplace(explode(' ', $search), '', $string) != $string) {
    echo "Found";
}

Or loop the words and check as you would with a single word:

foreach(explode(' ', $search) as $word) {
    if(stripos($string, $word) !== false) {
        echo "Found";
        break;
    }
}

I would use preg_grep and some other fancy things.

$string = "Apple is a big tech company!";
$search = 'Apple Logo a';

$pattern = '/\b('.str_replace(' ', '|', preg_quote($search, '/')).')\b/i';

$arr = preg_grep($pattern, explode(' ', $string));

print_r($arr);

Outputs

Array ( [0] => Apple [2] => a )

I threw the a in there just to show off. As you can see it only matches a not company etc..

And as a bonus it will properly escape any Regex stuff in the search string...

Yay!

As a side note you could also use the same pattern with preg_match_all if you wish.

$string = "Apple is a big tech company!";
$search = 'Apple Logo a';

$pattern = '/\b('.str_replace(' ', '|', preg_quote($search, '/')).')\b/i';

$numMatch = preg_match_all($pattern,$string,$matches);

print_r($numMatch);
print_r($matches);

Outputs

 2
 Array (
      [0] => Array (
           [0] => Apple
           [1] => a
      )
      [1] => Array (
           [0] => Apple
           [1] => a 
      )
 )

The only real difference is you get a more complicated array (just use $matches[1]) and the count of the matches without counting said array.

you can use this STRPOS example:

$a = 'How are you?';

if (strpos($a, 'are') !== false) {
    echo 'true';
}

this a little example.. good luck
