各位老大,帮忙检查一下语法吧,关于引号的用法,难煞小弟!
我打算用PHP输出一段 XML,有一句总是出错,语法不对!

PHP code
<!--

-->$strXML .= "<set name='"date_format($row["DatePro"],' value='".$row["Quantity"]."' hovertext=""></set>";


请指教,多谢了!!

------解决方案--------------------
PHP code


date_format($row["DatePro"],'%Y-%m')
这个两边少了连接符
<br><font color="#e78608">------解决方案--------------------</font><br>$strXML .= "<set name='" . date_format($row["DatePro"],' . value='" . $row["Quantity"] . "' hovertext=""></set>";<br>
<br><font color="#e78608">------解决方案--------------------</font><br>date_format对于参数,是有格式要求的,,你翻手册<br><br><br>可以尝试下,date_format(date_create($row["DatePro"]),'%Y-%m')
<br><font color="#e78608">------解决方案--------------------</font><br>date_format 的第一个参数应该是 DateTime 类型数据
<br><font color="#e78608">------解决方案--------------------</font><br>我看了下函数说明,加上$date = date_create($xxx); 看看 ,前面1万米已经说了<br>
<br><font color="#e78608">------解决方案--------------------</font><br>
PHP code

strtotime("Y-m-d H:i:s")//输出时间戳格式
date("Y-m-d H:i:s",time())//把时间戳格式输出成2011-02-1 12:0:0 格式 <div class="clear">
                 
              
              
        
            </div>

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.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

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),
