使用php重命名功能的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);
    }
?>

When I try to rename the file I get the following error:

****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

For some reason, you are adding a "newline" character ( PHP_EOL ) to the $a variable (which is then propagated to $change ). This causes rename to fail because this is not an allowed character in a filename.

The basic failing can be reproduced with

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

To fix your issue, just correct the line :

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