在PHP中显示mysql数据并爆炸

enter image description here

I want to display only the specific user details as shown in link. For kind information, I just want to say that I am using php and mysql and need to display 'user2' details from that previous table(customer) given as picture link].help with valuable suggestion.

Try this

SELECT id,rcvusr FROM xyz WHERE rcvusr like 'user2%' ORDER BY eid desc LIMIT 10

Select id, sndusr, SUBSTRING_INDEX(rcvusr, '@@', 1), title
From xyz
Where rcvusr = 'user2' or
    rcvusr like 'user2@@%'
