HomeBackend DevelopmentPHP Tutorial 小白继续。PHP中怎么把数组作为sql查询语句的条件

小白继续求助。。PHP中如何把数组作为sql查询语句的条件。
小白感谢各位大大对于自己上一个帖子的帮助,终于弄明白是怎么回事了。 现在遇到了另一个问题:

我通过一个页面让用户提交了12个多选列表,
获取出来就是12个数组,

然后根据这12个数组里的内容进行数据库搜索,

可是发现好像没有办法把这12个数组里的内容一项一项提取出来,然后写sql查询语句。。

比如:

$a = array(a,b,c,d);
$b = array(1,2,3,4);
$c = array(I,II,III,IV);
然后我想select * from 表名 where name=a AND name=b AND name=c AND name=d AND name=1 AND name=2..... AND name=IV

不知道如何可以实现呢?用foreach循环的话,只怕每次都是当前元素的值,这样查出来是每一个当前元素可以搜索到的结果。。。

但是我想查询的是所有数组里所有元素存在的条件下,最后的结果。。

求助各位高人!


------解决方案--------------------
呵呵,那么多AND可能找到东西么?

PHP code
$a = array('a','b','c','d');
$b = array(1,2,3,4);
$c = array('I','II','III','IV');
#保证$a,$b,$c任意一个非空数组,自己判断                                                                                                      
echo "select * from table where name='".implode("' OR name='",array_merge($a,$b,$c))."'";

在吃饭,给你提示<br>1个是将数组暑输出字符串 implode(',',$arr) 标点符号什么的自己再加工吧<br>1个是修改你的SQL 语句 将同个数组AND 什么的修改成 IN  <br>例如 IN ('a','b','c','d')<br><br>即可

例如 IN ('a','b','c','d')

即可


谢谢回复! 如果是name IN ('a','b','c','d'),那么应该是OR的关系吧?还是……

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),
