本篇文章的内容是php跨页面的三种传值方式，现在在这里分享给大家，也可以给有需要的朋友一个参考 一. POST传值 post传值是用于html的<form>表单跳转的方法，很方便使用。例如： <p class="toolbar" style="margin:0px;padding:0px;border:none;float:none;line-height:1.1em;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera

style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;">];</code><code class="php plain" style="font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier, monospace;font-size:1em;line-height:1.1em;padding:0px;margin:0px;border:0px;float:none;vertical-align:baseline;">?></code> </td> </tr></tbody></table> 这里有个很方便的小技巧，在input标签中把type选为'hidden'时，这个input标签会隐藏起来，不在页面显示，但这input标签在form中，并且有name值和value值，同样会跟随提交按钮传递过去，这种隐藏标签可以传递一些不想显示出来的内容。 二.GET传值 GET传值是通过跟随url传递的，在页面跳转时，跟着url跳转。常用于<a>标签的使用。例如： <p class="toolbar" style="margin:0px;padding:0px;border:none;float:none;line-height:1.1em;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier,

跳转进入xxx.php后，就能通过$_GET['id']获取传递的值。GET方法常用于URL的目的是删除或读取某个id的php文件。 三.SESSION传值 SESSION是全局变量的一种，经常用于用户登陆后保存用户id之类的常用数据。一旦保存到SESSION中，其他页面都可以通过SESSION获取,SESSION的使用要开启session： <p class="toolbar" style="margin:0px;padding:0px;border:none;float:none;line-height:1.1em;vertical-align:baseline;font-family:Consolas, 'Bitstream Vera Sans Mono', 'Courier New', Courier,

以上三种方式是常用方式，大家可以参考使用。 对于三种方式的利弊，get传值是显示在URL链接中，很不安全，如果是要链接到另一页面，post不太方便使用，选择session是一个很好很方便的方法 。<img src="https://img.php.cn/upload/article/000/153/291/9d327346da59a8eb93e1a2f9f28b3f63-0.png"
