HomeBackend DevelopmentPHP Tutorial怎样利用PHP将从数据库中读取的数据保存再变量中?

利用echo $myrow1[xm_name];可以输出项目名称,利用echo $myrow2[zf];可以得到项目的总分,可是如何在php中将其保存在变量中呢?$xm_name=$myrow1[xm_name];和$xm_zf=$myrow2[zf];两句中变量echo后无结果。

$query1=mssql_query("select * from tb_xm where xm_pcid='$xmpc_id'");		while($myrow1=mssql_fetch_assoc($query1)){		echo $myrow1[xm_name];                $xm_name=$myrow1[xm_name];/***************/		$query2=mssql_query("select sum(xmpf_small_zf) as zf from tb_xmpf where xmpf_xm='$myrow1[xm_name]'");					//echo $query2;		echo "总分:";		while($myrow2=mssql_fetch_assoc($query2)){		 echo $myrow2[zf];                 $xm_zf=$myrow2[zf];		 }


回复讨论(解决方案)

 echo $myrow1[“xm_name']你试试,数组字段名称要加印号

 我想将 $myrow1[“xm_name']保存到$xm_name中该怎么做?

你那样写有什么问题

报错说Parse error: syntax error, unexpected T_STRING in C:\AppServ\www\online_pf\admin\jgcx_zt_ok.php on line 14

打错了,是echo $xm_name;无反应。

在你的例子中直接 echo $myrow1[xm_name]; 不就可以了,还用变量干什么?

因为我想把数据保存到变量中,在写一个数据更新的语句,如果不用变量直接写

$query3=mssql_query("update tb_xm set xm_zf='$myrow2[zf]' where xm_name='$myrow1[xm_name]'");

系统会报错说Parse error: syntax error, unexpected T_STRING in C:\AppServ\www\online_pf\admin\jgcx_zt_ok.php 

 $xm_name = $myrow1[“xm_name'];

$query3=mssql_query("update tb_xm set xm_zf='$myrow2[zf]' where xm_name='$xm_name'");

你的结尾分号是全角的,改为半角就可以了。

$query3=mssql_query("update tb_xm set xm_zf='$myrow2[zf]' where xm_name='$myrow1[xm_name]'");
  

8楼的方法还是报错...Parse error: syntax error, unexpected T_STRING in C:\AppServ\www\online_pf\admin\jgcx_zt_ok.php on line 15

太感谢了!是分号的问题,输入法混用了!再次感谢大家的热心帮助!

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),
