mysql - Wordpress function to check if table is empty -

i running wp blog on mediatemple wp hosting. provide built-in function integrate google analytics code. need make changes ga tracking code in order anonymize users ip, want disable function , replace custom one.

here mt built-in function:

    public function add_ga_tracking_snippet_to_head() {     if ( get_option( $this->plugin->name . '_web_property_id_head' ) !== false ) {         $web_property_id = get_option( $this->plugin->name . '_web_property_id_head' ); ?> <script>   (function(i,s,o,g,r,a,m){i['googleanalyticsobject']=r;i[r]=i[r]||function(){   (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new date();a=s.createelement(o),   m=s.getelementsbytagname(o)[0];a.async=1;a.src=g;m.parentnode.insertbefore(a,m)   })(window,document,'script','//www.google-analytics.com/analytics.js','ga');    ga('create', '<?php echo $web_property_id ?>', 'auto');   ga('send', 'pageview'); </script> <?php     } } 

and here screenshot of db table ga id stored:

now, if delete id inside option_value table, function should not print <script>...</script>, because of conditional statement if ( get_option( $this->plugin->name . '_web_property_id_head' ) !== false ) doesn't work way.

here's instead:

p.s. i've tried alter function isset , !empty no success. wrong?

the line get_option( $this->plugin->name . '_web_property_id_head' ) must false conditional not execute.

empty strings , null in mysql aren't boolean values they're never going !== false.
