使用php重命名函数的php文件重命名错误

Question

<?php
    while($data = mysqli_fetch_array($result))
    { 
        $q1="insert into delinked values('".$data[0]."','".$data[1]."','".$data[2]."');"; //inserts the all the data into delinked 
        //$result1=mysqli_query($conn,$q1)or die("error");//executes query
        $a=basename($data[2]).PHP_EOL;//gets the filename
        $change="D".$a; // changes the file in (D_filename format)
        $tar="/DATA".$change;

        chdir('E:\DATA');
        rename($a,$change);
    }
?>

当我尝试重命名文件时，出现以下错误:

****Warning: rename(E:/DATA/windows.rar ,E:/DATA/er.php): The filename, directory name, or volume label syntax is incorrect. (code: 123) in C:\Users\yathi\Desktop\Cilicosys Project\deactivate.php on line 27****

Answer 1

出于某种原因，您要向 $a 变量添加一个“换行”字符 (PHP_EOL)(然后传播到 $change)。这会导致 rename 失败，因为这不是文件名中允许的字符。

基本失败可以重现

$a = "test.tst".PHP_EOL;                  
$targ = "moved.tst".PHP_EOL;                      
rename($a, $targ);
/*
Outputs : Warning. No such file or directory
*/

要解决您的问题，只需更正以下行:

$a=basename($data[2]); //gets the filename
