Home Backend Development PHP Tutorial 怎么循环追加打印罗列出多个select出来的结果

怎么循环追加打印罗列出多个select出来的结果

Jun 23, 2016 pm 02:17 PM


首先:$names = array("关键词1","关键词2","关键词3");


然后依次对关键字进行select查询,再打印出来。下面的程序只能打印最后依次关键字3的结果。求帮忙解决下。O(∩_∩)O谢谢

for($i=0; $i $query="SELECT * from te where title like \"$names[$i]\"";
$result=@mysql_query($query)or die('查询语句出错:'.mysql_error());

while(!!$row=mysql_fetch_array($result)){
echo $row['id'].'----'.$row['title'].'----'.$row['url'];
echo '
';
}}

是不是前2个没有搜索结果啊?

那有什么?不过只是 关键字3 有结果而已

like 没有通配符,就相当于= 号。只能说明你表中没有title=关键词1 和 title=关键词2 d的数据。

是不是前2个没有搜索结果啊? 是的。只打印出了查询关键字3所匹配的结果。我要三个关键字的结果都显示呢?我怀疑是while的问题

like 没有通配符,就相当于= 号。只能说明你表中没有title=关键词1 和 title=关键词2 d的数据。 亲,有的。就算我自定义三个数据的数组,也只能显示第三个数据的查询匹配结果呢。我要3个关键字都要列出来

那有什么?不过只是 关键字3 有结果而已 版主大人,我要实现3个关键字的结果都要罗列出来。而不仅仅是第3个关键字的匹配结果

我不太相信,你把你的表数据和页面输出结果截个图贴出来看看。

你先搞清楚“包含”和“等于”的区别在说

用  title like "%{$names[$i]}%"
或者 INSTR(title,"{$names[$i]}")

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
