php字串比较有关问题，看起来明明一样，strcmp比较结果始终不为0
php字串比较问题，看起来明明一样，strcmp比较结果始终不为0
一个从页面传入 id值是1 ，
一个是从文件里面读取的id值是1
使用strcmp比较的时候始终不等，然后用strlen来测试字串长度 传入的1的长度居然是0,从文件里面读取到的1长度是1.现在考虑是编码不一致引起的，但是怎么设置啊？请指教，谢谢。
------解决方案--------------------
你看看你的文件的编码 是什么
转变哈
然后看看你的代码文件的编码是什么 转变哈
------解决方案--------------------
还是要看代码，长度为0是奇怪的
------解决方案--------------------
五码无真相，贴出代码看看。
------解决方案--------------------
确认你的值传入了...
------解决方案--------------------
我之前也遇到过 就是两个值 在页面输出看起来是一样 比较是返回false的
不过我的情况不一样，我那个"变质"的值是因为经过一层层打包 再拆封 传输，才变质的。
因为变质的值strlen非常长，我后面是用trim()去掉空格 进行比较才返回true.LZ的比较奇怪 直接就是0了 LZ再比较比较吧 用gettype dump 输出 看看有什么不一样~
------解决方案--------------------
是不是值没有传过来，仔细检查下看看，
可以的话把代码拿过来看看，
