mysql_pconnect() vs mysql_connect()

When connecting, the pconnect wolud first try to find a (persistent) link that’s already open with the same host, username and password. If the link already exist then the identifier for that will be returned instead of opening a new connection. Later, create a new link for each connection.

The Connection to the SQL server will not be closed when the execution of the script ends. Instead the link will be opened for future use and mysql_close() will not will not close links established by mysql_pconnect(). Later, The link to the server will be closed as soon as the execution of the script ends, unless its closed earlier by explicitly calling mysql_close().

Reference: mysql_pconnect() and mysql_connect()

Quote from Bible for Valentine’s day

Jesus said this:

But I tell everyone who is listening:
Love your enemies.
Be kind to those who hate you.
Bless those who curse you.
Pray for those who insult you.
If someone strikes you on the cheek, offer the other cheek as well. If someone takes your coat, don’t stop him from taking your shirt.
Give to everyone who asks you for something. If someone takes what is yours, don’t insist on getting it back.

Do for other people everything you’d like them to do for you.

If you love those who love you, do you deserve any thanks for that? Even sinners love those who love them.
If you help those who help you, do you deserve any thanks for that? Sinners do that too.
If you lend anything to those from whom you expect to get something back, do you deserve any thanks for that? Sinners also lend to sinners to get back what they lend.
Rather, love your enemies, help them, and lend to them without expecting to get anything back. Then you will have a great reward. You will be the children of the Most High God. After all, he is kind to unthankful and evil people. Be merciful as your Father is merciful.

Stop judging, and you will not be judged.
Stop condemning, and you will not be condemned.
Forgive, and you will be forgiven.
Give, and you will receive. A large quantity, pressed together, shaken down, and running over will be put into your pocket.
The standards you use for others will be applied to you.
