This article is about PHP and how it works. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

For information only, the details are as follows:

1. Print out the previous day's time in PHP format is 2006-5-10 22:21:21(2 minutes)

$a = date("Y-m-d H:i:s", strtotime("-1 day"));print_r($a);

echo(),print(),print_r()

Echo and print are not a function, they are a language construct.

int print(string $arg), only one argument

echo arg1,arg2; can output multiple parameters, return void

echo and print can only print strings, not structures

print_r can print structure

such as

$arr = array("key"=>"value");print_r($arr);
