Description
array explode
( string separator, string string [, int limit])phpma.com
Returns an array of strings, each of which is a substring of string
formed by splitting it on boundaries formed by the string separator
. If limit
is set, the returned array will contain a maximum of limit
elements with the last element containing the rest of string
.
If separator
is an empty string (""), explode()
will return FALSE
. If separator
contains a value that is not contained in string
, then explode()
will return an array containing string
.
If the limit
parameter is negative, all components except the last limit
are returned. This feature was added in PHP
5.1.0
.
Although implode()
can, for historical reasons, accept its parameters in either order, explode()
cannot. You must ensure that the separator
argument comes before the string
argument.
注:
The limit
parameter was added ......
time()在PHP中是得到一个数字,这个数字表示从1970-01-01到现在共走了多少秒,很奇怪吧
不过这样方便计算,
要找出前一天的时间就是 time()-60*60*24;
要找出前一年的时间就是 time()-60*60*24*365
那么如何把这个数字换成日期格式呢,就要用到date函数了
$t=time();
echo date("Y-m-d H:i:s",$t);
a - "am" 或 "pm"
A - "AM" 或 "PM"
B - Swatch Internet Time（【译者注】参见 http://swatch.com/alu_beat/fs_itime.html）
d - 月份中的第几天，有前导零的 2 位数字，例如 "01" to "31"
D - 星期中的第几天，文本表示，3 个字母，例如 "Fri"
F - 月份，完整的文本格式，例如 "January"
g - 小� ......
