怎样用PHP创建PDF中文文档
我使用的是FPDF(www.fpdf.org),下载了fpdf类库后,还要使用下面的中文类库才能支持中文,但只能使用一种中文字体(华文仿宋)。为此我烦恼了很长时间,现在终于搞定了,将TrueType字体转化为pt1字体使用:
下面是在FPDF上找的一个中文类库:
require('fpdf.php');

将以上代码存为chinese.php即可引用。但用它只能得到一种字体。为了支持所有中文字体,可用ttf2pt1程序将TrueType字体转化pt1字体,一个一个地转(具体方法在FPDF的教程中有详细说明)。为了支持其他中文字体,养分要修改上面的chinese.php,如下:
1: Replace the following line in the AddGBFont() method:
function AddGBFont($family='GB',$name='STSongStd-Light-Acro')
{
$cw=$GLOBALS['GB_widths'];
// $name='STSongStd-Light-Acro';
$CMap='GBKp-EUC-H';
........
2: This is a Sample.
require('chinese.php');
$pdf=new PDF_Chinese();
$pdf->AddGBFont('simsun','宋体');
$pdf->AddGBFont('simhei','黑体');
$pdf->AddGBFont('simkai','楷体_GB2312');
$pdf->AddGBFont('sinfang','仿宋_GB2312'');
$pdf->Open();
$pdf->AddPage();
$pdf->SetFont('simsun','',20);
$pdf->Write(10,'简体中文汉字‘);
$pdf->SetFont('simhei','',20);
$pdf->Write(10,'简体中文汉字’);
$pdf->SetFont('simkai','',20);
$pdf->Write(10,'简体中文汉字‘);
$pdf->SetFont('sinfang','',20);
$pdf->Write(10,'简体中文汉字’);
$pdf->Output();
?>
以上就介绍了怎样用PHP创建PDF中文文档,包括了方面的内容,希望对PHP教程有兴趣的朋友有所帮助。

PHP是一种服务器端脚本语言,用于动态网页开发和服务器端应用程序。1.PHP是一种解释型语言,无需编译,适合快速开发。2.PHP代码嵌入HTML中,易于网页开发。3.PHP处理服务器端逻辑,生成HTML输出,支持用户交互和数据处理。4.PHP可与数据库交互,处理表单提交,执行服务器端任务。

PHP在过去几十年中塑造了网络,并将继续在Web开发中扮演重要角色。1)PHP起源于1994年,因其易用性和与MySQL的无缝集成成为开发者首选。2)其核心功能包括生成动态内容和与数据库的集成,使得网站能够实时更新和个性化展示。3)PHP的广泛应用和生态系统推动了其长期影响,但也面临版本更新和安全性挑战。4)近年来的性能改进,如PHP7的发布,使其能与现代语言竞争。5)未来,PHP需应对容器化、微服务等新挑战,但其灵活性和活跃社区使其具备适应能力。

PHP的核心优势包括易于学习、强大的web开发支持、丰富的库和框架、高性能和可扩展性、跨平台兼容性以及成本效益高。1)易于学习和使用,适合初学者;2)与web服务器集成好,支持多种数据库;3)拥有如Laravel等强大框架;4)通过优化可实现高性能;5)支持多种操作系统;6)开源,降低开发成本。

PHP没有死。1)PHP社区积极解决性能和安全问题,PHP7.x提升了性能。2)PHP适合现代Web开发,广泛用于大型网站。3)PHP易学且服务器表现出色,但类型系统不如静态语言严格。4)PHP在内容管理和电商领域仍重要,生态系统不断进化。5)通过OPcache和APC等优化性能,使用OOP和设计模式提升代码质量。

PHP和Python各有优劣,选择取决于项目需求。1)PHP适合Web开发,易学,社区资源丰富,但语法不够现代,性能和安全性需注意。2)Python适用于数据科学和机器学习,语法简洁,易学,但执行速度和内存管理有瓶颈。

PHP用于构建动态网站,其核心功能包括:1.生成动态内容,通过与数据库对接实时生成网页;2.处理用户交互和表单提交,验证输入并响应操作;3.管理会话和用户认证,提供个性化体验;4.优化性能和遵循最佳实践,提升网站效率和安全性。

PHP在数据库操作和服务器端逻辑处理中使用MySQLi和PDO扩展进行数据库交互,并通过会话管理等功能处理服务器端逻辑。1)使用MySQLi或PDO连接数据库,执行SQL查询。2)通过会话管理等功能处理HTTP请求和用户状态。3)使用事务确保数据库操作的原子性。4)防止SQL注入,使用异常处理和关闭连接来调试。5)通过索引和缓存优化性能,编写可读性高的代码并进行错误处理。

在PHP中使用预处理语句和PDO可以有效防范SQL注入攻击。1)使用PDO连接数据库并设置错误模式。2)通过prepare方法创建预处理语句,使用占位符和execute方法传递数据。3)处理查询结果并确保代码的安全性和性能。

mPDF是一个PHP库,可以从UTF-8编码的HTML生成PDF文件。原作者Ian Back编写mPDF以从他的网站上“即时”输出PDF文件,并处理不同的语言。与原始脚本如HTML2FPDF相比,它的速度较慢,并且在使用Unicode字体时生成的文件较大,但支持CSS样式等,并进行了大量增强。支持几乎所有语言,包括RTL(阿拉伯语和希伯来语)和CJK(中日韩)。支持嵌套的块级元素(如P、DIV),
