How to: compare array elements with a String

Question

I have predefined an array:

$tags = array('PHP', 'Webdesign', 'Wordpress', 'Drupal', 'SQL');

Now I am inputting a value into a text area:

$text = 'Working With Wordpress Shortcodes and doing some NoSQL and SQL';

How can I compare the string value with the predefined array?

The desired result I want based on the above is 'Wordpress' and 'SQL'

Can I do it in PHP and JQuery?

Also, if it will contain a regular expression like

Working With Wordpress; Shortcodes: and doing some NoSQL and ""SQL

Then what to do?

You should split your string like so

$array = explode( ' ', $text );

Then compare like so

$result_array = array_intersect($tags, $array);

Now result_array will contain every value that is in both of the arrays :)

Using explode split the string to works, than for each word check in_array

$words = explode(' ', $text);
$result = array();
foreach ($words as $word) {
   if (in_array($word, $tags)) {
      $result[] = $word;
   }
}

Note: the comparision will be case-sensitivive

foreach(explode(' ', $text) as $word) {
  if(in_array($word, $tags)) {
    // This word is in our tags array, do something.
  }
}

i have found some solution and it works perfectly for me. Firstly i am rearranged the string with a "," separated using

var valsp = $('#desc').val(); var results = valsp.split(/\W+/);

after this just using inArray() i am getting the desired result

Hope it will help to others
