cmd执行php文件：

php index.php
php -f  index.php 
php -f  index.php  start
php -q  index.php  
php -q  index.php  start

php文件里如果引用了相对路径则是相对于当前执行命令所在的文件路径

代码文件路径：D:\WorkSpace\qpl_system\index.php

如果cmd在 D:\WorkSpace下执行，则代码里test.log生成当前文件夹下

如果cmd在 D:\WorkSpace\qpl_system下执行，则代码里test.log生成当前文件夹下

    $s = 0;//从0开始
    $e = 10; //取10条数据
while(true){//死循环模拟分页执行代码

     if($s >=100){//满足条件跳出死循环
         exit('success');
     }  
    //执行代码
    file_put_contents('./test.log',$s.'--'.$e."\n",FILE_APPEND);
    
    $s = $s+$e; //下次分页开始
}

php

#ctr+z再回车，输出结果
