strtotime()函数的作用是将日期时间描述解析为 Unix 时间戳
int?strtotime?( string time [, int now] )
?>
本函数预期接受一个包含美国英语日期格式的字符串并尝试将其解析为 Unix 时间戳(自 January 1 1970 00:00:00 GMT 起的秒数),其值相对于?now?参数给出的时间,如果没有提供此参数则用系统当前时间。
-------------------------------

在PHP里得到前天和昨天的日期的代码
前天去面试的时候也是这样,不过我当时记不起来了.就记得MYSQL里面的date_sub(now(),'interval 1 day');date('Y/m/d h:i:s',mktime(date('h'), date('i'), date('s'), date('m') , date('d')+1, date('Y')));
--------------------------------------------?
先得到今天的UNIXTIME?
然后减去一天或两天的秒数?
把减后的UNIXTIME格式化成日期。?
--------------------------------------------
以下为引用的内容:
date_default_timezone_set('Asia/Shanghai');?
#昨天?
echo date("Y/m/d h:i:s",time()-24*60*60);?
echo "
";?
#前天?
echo date("Y/m/d h:i:s",time()-2*24*60*60);?
?>?
--------------------------------------------?
up?
--------------------------------------------?
方法有很多种啊, 我也介绍一种吧:?
date("Y/m/d H:i:s", strtotime("1 days ago"));?
date("Y/m/d H:i:s", strtotime("2 days ago"));?
--------------------------------------------?
date("Y/m/d H:i:s",mktime(0,0,0,date("m"),date("d")-1,date("Y")));?
--------------------------------------------?
以前算时间总是很烦人,呵呵,学了了下,下面是下个星期现在的时间。?
date_default_timezone_set('Asia/Shanghai');?
$tmp = time()+60*60*24*7;?
print date("m/d/Y H:i:s", $tmp);?
--------------------------------------------?
再加一个:?
$time_yes=localtime(time()-24*60*60, true);?
$time_b_yes=localtime(time()-2*24*60*60, true);?
$yesterday=$time_yes['tm_mday'];?
$the_day_before_yes=$time_b_yes['tm_mday'];?
--------------------------------------------?
time()-86400 昨天的
以下为引用的内容:
?
//昨天?
print date('Y-m-d' , strtotime('-1 day'));?
//上星期?
print date('Y-m-d' , strtotime('-1 week'));?
//上个月?
print date('Y-m-d' , strtotime('-1 month'));?
//去年?
print date('Y-m-d' , strtotime('-1 year'));?
?>
--------------------------------------------
strtotime得到一个时间戳, 然后你自己格式化.?
strtotime('yesterday');?
strtotime('-2 day');

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
