I have this database row from where I need to pull the database row only with specific row value such as template_number == 'template-1'. And the row value is in array similar to this
a:1:{s:11:"design";a:5:{s:19:"style";s:7:"default";s:15:"template_number";s:10:"template-4";s:20:"custom_template_type";s:1:"1";s:14:"menu_placement";s:5:"right";}}
