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?

Answer 1

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 🙂
