下面有一個PHP代碼可以在當前目錄中創建多個目錄。如果目錄已經存在，我需要終止腳本。但相反，我收到多個“文件存在”警告消息。法典<?php//Creates multiple directories inside the current directory.$curdir = getcwd();$slash = "/0";for ($dir = 1; $dir <= 12; $dir++){ $concat = $slash . $dir; if (!file_exists($concat)) { mkdir($curdir . "$concat" , 0777); } else { exit("Files already exist."); }} ?>輸出Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14Warning: mkdir(): File exists in /opt/lampp/htdocs/SQL/mkdir.php on line 14

您必須編輯 if 語句。您正在檢查的目錄與您創建的目錄不同的目錄：
<?php
$curdir = getcwd();
$slash = "/0";
for ($dir = 1; $dir <= 12; $dir++){
$concat = $slash . $dir;
if (!file_exists($curdir . $concat)) {
mkdir($curdir . $concat , 0777);
} else {
exit("Files already exist.");
}
}
