Check if the data is exist in mysql PHP

I am looking for a freelancer who are expert in PHP. I need some help with my code as I have got a problem with my code. I want to check in the send_autoresponder table that if the email and subject data is exist then I am fetching the data in the array to see if the data is between "Same Time" and "Different Time". If the data is different time then I am fetching the data from the array. My problem is that I am unable to send the email when I am using this code "$send_now = ($mail_day_cycle !== 0) ? (strtotime('-1 day') > strtotime($send_time) && $auto_responders[$mail_day_cycle]['day_cycle'] && $auto_responders[$mail_day_cycle]['enabled'] === 'yes') : true;" but if I use this "$send_now = ($mail_day_cycle !== 0) ? (strtotime('-1 day') < strtotime($send_time) && $auto_responders[$mail_day_cycle]['day_cycle'] && $auto_responders[$mail_day_cycle]['enabled'] === 'yes') : true;" it will keep sending me the email. I need your help to fix this issue. If you can be able to help me with my requirement to fix it for $30 that will be great. When you have done, please invite me to teamviewers or send me the screenshot for demo. I look forward to work with you. No time wasters please.
