遇到php变量 赋值怪事............
今天修改程序的时候遇到的怪事.
我先直接赋值
$swfpath="F:/ComsenzEXP/wwwroot/docs/2012/09/10/";
$pdfpath="F:/ComsenzEXP/wwwroot/filestores/2012/09/10/";
这样程序能运行
但是我把上面的变量改成这样后,程序就不能运行了
$swfpath=$_SERVER[DOCUMENT_ROOT]."/docs/".$file['file_store_path'];
$pdfpath=$_SERVER[DOCUMENT_ROOT]."/".$settings['file_path']."/".$file['file_store_path'];
echo出来的值完全一样,请问这是什么原因造成的....
因为不能显示错误,所以前来求助

还是这个程序,$page=$_GET['page'];程序正常,但是直接赋值就不行了如$page="[*,0],8";尽管他们echo出来的值一模一样,真是见鬼了.......

这个程序就是FlexPaper php的演示程序,我想把他嵌入到我的程序中,中间遇到这么些郁闷问题


------解决方案--------------------
1. $_SERVER[DOCUMENT_ROOT],由于没有给键值加引号来告诉PHP这是一个字符串,将会产生一个notice级别的错误,可能会引发之后的header()函数出错,进而产生warning级别的错误。如果不能显示错误,PHP将自行终止
2. $page=$_GET['page'];程序正常,但是直接赋值就不行了如$page="[*,0],8";
不知道你说的不行是什么情况?
------解决方案--------------------
var_dump("F:/ComsenzEXP/wwwroot/docs/2012/09/10/" == $_SERVER[DOCUMENT_ROOT]."/docs/".$file['file_store_path']);

------解决方案--------------------
在程序头加上着两行,再看看提示是什么错误。

PHP code
ini_set('display_errors', 'On');
error_reporting(E_ALL); <div class="clear">
                 
              
              
        
            </div>

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF

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),
