数组随机排序怎么随机排序
在1.2.3.4文本里面随机选择一行,然后组合成一句话,比如:
去干嘛,去吃饭,太好了,么么哒
或者
太好了,吃饱了,做什么,开心
回复讨论(解决方案)
$filenames=array('1.txt','2.txt','3.txt','4.txt');$str='';foreach($filenames as $k=>$file){ $tmp=file_get_contents($file); $data[$k]=explode(PHP_EOL,$tmp); $str.=$data[$k][array_rand($data[$k])].',';}echo $str;//太好了,吃饭了,去干嘛,谢谢,
$filenames=array('1.txt','2.txt','3.txt','4.txt');$str='';foreach($filenames as $k=>$file){ $tmp=file_get_contents($file); $data[$k]=explode(PHP_EOL,$tmp); $str.=$data[$k][array_rand($data[$k])].',';}echo $str;//太好了,吃饭了,去干嘛,谢谢,
测试了,你这个排序是顺序的,比如说从1.txt读取一行,接着2.txt读取一行,接着3.txt读取一行,4.txt读取一行组成的一句话。
我想要的效果是随机从1.2.3.4文本读取一行组成一句话。
在 $filenames=array('1.txt','2.txt','3.txt','4.txt'); 下面加上这一句
shuffle($filenames);
在 $filenames=array('1.txt','2.txt','3.txt','4.txt'); 下面加上这一句
shuffle($filenames);
