根据自己的电脑系统和php的版本号选择,NTS是线程不安全,TS是线程安全
根据phpinfo(),选择是否是线程安全
把php_yaf.dll扩展放到ext目录下
重启apache
使用
新建目录public,新建文件index.php入口文件
<?<span>php define(</span>"APP_PATH", realpath(dirname(__FILE__) . '/../')); <span>/*</span><span> 指向public的上一级 </span><span>*/</span><span> $app </span>= <span>new</span> Yaf_Application(APP_PATH . "/conf/application.ini"<span>); $app</span>->run();
新建目录conf,新建文件application.ini
<span>[product] ;支持直接写PHP中的已定义常量 application</span>.directory=APP_PATH "/application/"
新建目录application/controllers,新建文件index.php
<?<span>php </span><span>class</span> IndexController <span>extends</span><span> Yaf_Controller_Abstract { </span><span>public</span> <span>function</span> indexAction() {<span>//</span><span>默认Action</span> <span>$this</span>->getView()->assign("content", "Hello Yaf"<span>); } }</span>
新建目录views/index,新建文件index.phtml
<h1><?php <span>echo</span> <span>$content</span>;?></h1>

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

mPDF
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),
