求一段php调用txt文件数据并赋值的代码

Jun 23, 2016 pm 02:23 PM

引用变量 引用txt if...else 判断语句

首页文件 index.html
引用文件:./txt/pan.txt中的第三行:false或者yes
在index.html中做一个if..else的判断语句,变量$do的值是pan.txt的第三行中的数值;

这个php该怎么写呢?

回复讨论(解决方案)

<?php$myFile = "./txt/pan.txt";$lines = file($myFile);//文件放入数组中$do = $lines[3]; //line 3if ($do == "false") {    echo "false, do ..."; //false的做的事情} elseif ($do == "yes") {    echo "yes, do....";  //yes的时候做的事情} else {    echo "not supported"; //其他值}?>
Copy after login
Copy after login

写错了,刚刚是line 4

<?php$myFile = "./txt/pan.txt";$lines = file($myFile);//文件放入数组中$do = $lines[2]; //line 3 if ($do == "false") {    echo "false, do ..."; //false的做的事情} elseif ($do == "yes") {    echo "yes, do....";  //yes的时候做的事情} else {    echo "not supported"; //其他值}?>

Copy after login
Copy after login

thank you!不过如果要输出的不是一句话而是一个div层呢?该怎么做呢?

其实要输出是这么一个

    ,如果do的值为yes 就输出,为false就不输出,请问这个怎么实现呢?
    <ul>							{query:name=commend_goods as co join=left join goods as go on co.goods_id eq go.id where=co.commend_id eq 1 and go.is_del eq 0 AND go.id is not null fields=go.list_img,go.sell_price,go.name,go.market_price,go.id limit=7 order=id desc group = id}		{set:$tmpId=$item['id'];}				<li>		    <span class="goods_img">		    <a href="{url:/site/products/id/$tmpId}" target="_blank">		     <img src="/static/imghw/default1.png"  data-src="{webroot:$item[list_img]}"  class="lazy"    alt="{$item['name']}" />                     </a></span>		     <h3 id="item-name">{$item['name']}</h3>		     <p><span class="moneda">RMB</span><span class="sell_price">{$item['sell_price']}</span></p>			</li>				{/query}								</ul>

    你的这个是模板语言?

    如果知识输出,你修改一下,直接echo "

      "就好了,false的情况下不做处理,都不用判断,就判断是否为yes

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
