如何将这个数组插入我的表mysql php？

I have a problem to insert the following array into my mysql table. I want to insert the array value (abdominal pain,back pain, pain, abd) into my table, but I have no idea to do that on this complicate array. Appreciate.

<?php
$data = array(
  array("table"=>"abdominal pain"),
  array("table"=>"back pain"),
  array("table"=>"pain"),
  array("table"=>"abd")
);

$add_word = $wpdb->query( $wpdb->prepare( 
    "
        INSERT INTO $word_table
        ( word )
        VALUES ( %s )
    ", 
    $data
) );
?>

</div>

You can serialize() the value and insert it as a string. Then when you retrieve it, unserialize() it and it will be an array again.
