How to convert date to time in PHP?

Hi, programmer. The PHP programming language has several useful functions for getting and manipulating the date and time. The PHP "time()" function is used to get the current Unix timestamp, a number representing the number of seconds since January 1, 1970 Greenwich Mean Time (GMT). This number is handy for generating unique and random numbers, but as a readable date and time, it leaves much to be desired. Luckily, the PHP "date()" function was designed to format this timestamp using a custom format. I google search and found some PHP Date time scripts listed on the page. Glad to sharing with guys and girls who interested in PHP. Hopefully can help you! Best regards! Anny
