说明:从一个页面采集ip和端口,$ip和$duankou是采集的,然后发现不能用,但是手动输入可以用,对比了
两个字符串,发现长度不相同,但是编码相同,请教这该怎么办
现在是 $b 是有效的,$a无效,
$a="tcp://".$ip.":".$duankou;$b="tcp://77.81.105.147:7808";echo $a."<br>";echo $b."<br>"; $encode = mb_detect_encoding($a, array("ASCII","UTF-8","GB2312","GBK","BIG5")); $encodes= mb_detect_encoding($b, array("ASCII","UTF-8","GB2312","GBK","BIG5")); echo $encode."<br>"; echo $encodes."<br>"; $changdu1= strlen($a); $changdu2= strlen($b); echo $changdu1."<br>"; echo $changdu2;if($a==$b){echo "相等";}else{echo "不等";}
//字符tcp://77.81.105.147:7808tcp://77.81.105.147:7808//编码ASCIIASCII//长度4224//结果不等
var_dump($a, $b, $encode, $encodes);
贴出结果
最好是
echo base64_encode(serialize(array($a, $b, $encode, $encodes)));
贴出结果
采集的数据里有不可见的空字符吧,把ip和port trim()一下试试

原来问题在这,我疏忽了,多谢了
