QM项目开发文档整理

前言

在W公司工作4个多月,庆幸接触到的全是“硬”项目,真枪实干,技术、经验、能力都得到了很大提升。

QM项目

此项目WEB前端学到的东西很多,对PHP项目的架构设计、MVC框架有了更深的认识。

CSS知识汇总

垂直对齐一幅图像,可用vertical-align属性,如:

<code>img{    vertical-align:text-top;}</code>

对于浮动元素记得清除浮动,清除浮动的通用代码如下,高级浏览器可使用after伪类:

<code>.c,.fix:after{    clear:both;    display:block;    margin:0;    padding:0;    height:0;    overflow:hidden;    content:'.'}.fix{    zoom:1}</code>

display: inline-block 将对象呈递为内联对象,但是对象的内容作为块对象呈递。旁边的内联对象会被呈递在同一行内,允许空格。所以对于像三张图片横排的需求,可以如此定义,并加IE hack解决兼容性问题:

<code>.div{    display: inline-block;    *display: inline;}</code>

MYSQL知识汇总

MYSQL从指定位置开始取数据

<code>SELECT * FROM  表  LIMIT 0, 10;</code>

说明如下:

  1. LIMIT 接受一个或两个数字参数。
  2. 参数必须是一个整数常量。
  3. 如果给定两个参数,第一个参数指定第一个返回记录行的偏移量,
  4. 第二个参数指定返回记录行的最大数目。
  5. 初始记录行的偏移量是 0(而不是 1)

INSET INTO用于向表中插入数据,格式如下:

<code>INSERT INTO table_name (列1, 列2,...) VALUES (值1, 值2,....);</code>

PHP知识汇总

PHP时间戳与date格式转换

  • 输出PHP时间戳:

    <code>echo time();</code>
  • 普通日期输出:

    <code>echo date('Y-m-d');//输出类似2015-04-04</code>
  • PHP时间戳转成普通日期形式:

    <code>$date=date('Y-m-d',"1285724523"); echo $date; </code>
  • PHP日期转时间戳:

    <code>$date=date('Y-m-d',"1285724523"); $temp=explode("-",$date); echo mktime(0,0,0,$temp[1],$temp[2],$temp[0]); </code>

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.
