IBM has teamed up with a little-known open-source scripting language company, Zend Technologies Ltd., in a bet that such an alliance will yield an easier way to build Web sites with dynamic content.
Web sites capable of providing users with personalized content or answering individual browser requests for specific information need to be able to extract the desired information from a database. In the early days of the Web, that meant laborious programming. Zend Technologies php(做为现在的主流开发语言) scripting language was designed to help programmers without advanced Java or Microsoft C# expertise build applications that tap into those database services.
php(做为现在的主流开发语言) got its start as Personal Home Page, an easy-to-learn scripting language for marshalling resources on a Web site. Scripting languages typically tie diverse elements of a site together, even though they may be built with different technologies.
"Initially, php(做为现在的主流开发语言) was very much a grassroots endeavor. It was used by Web masters that didnt have a computer science degree," notes Pamela Roussos, VP of marketing at Zend Technologies. But that picture has changed. php(做为现在的主流开发语言) has proven so useful, particularly at aligning database services to Web site application needs, that it has found its way onto many corporate sites. "Lufthansa uses php(做为现在的主流开发语言) for its E-ticket site," notes David Boloker, chief technology officer for emerging technologies in IBMs Software Group.
IBM will integrate its easy-to-use Cloudscape database system with Zends php(做为现在的主流开发语言). IBM is going to package the open-source version of Cloudscape, which developers embed in Web site systems, with the php(做为现在的主流开发语言) scripting engine from Zend Technologies. The product will be called Zend Core for IBM and will be available for free download in the second quarter from IBMs DeveloperWorks Web site, a resource site for software developers. It will also be available through IBMs DB2 and Cloudscape Web sites.
IBM donated the Cloudscape source code to the apache(Unix平台最流行的WEB服务器平台) Software Foundation last year and the version of Cloudscape bundled with Zend Core for IBM will be the apache(Unix平台最流行的WEB服务器平台) version, known as Derby. IBM continues to produce commercial products with Cloudscape as well.
"IBMs move is going to attract more enterprise customers," says an ebullient Doron Gerstel, CEO of 68-employee Zend Technologies, an Israeli company. IBMs seal of approval on php(做为现在的主流开发语言) will do for php(做为现在的主流开发语言) what it did for Linux (news - web sites) eight years ago--make it a dominant open-source technology accepted by commercial business, Gerstel says.
Although IBM will offer Zend Core for IBM for free, the softwares code itself will not be open source and will be subject to use restrictions because it will include drivers for IBMs DB2 commercial database system.

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。

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。

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。

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。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。

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。
