Warning: preg_replace(): No ending delimiter '/' found
提问by UnleashDchaos
Warning: preg_replace(): No ending delimiter '/' found in C:\wamp\www\upload\upload_demo.php on line 77 I used preg_replace() to replace slash to backslash. But it shows the above warning. Here is the code..
警告：preg_replace()：在第 77 行的 C:\wamp\www\upload\upload_demo.php 中找不到结束分隔符 '/' 我使用 preg_replace() 将斜杠替换为反斜杠。但它显示了上述警告。这是代码..
function del_file($file) {
$delete = @unlink($file);
clearstatcache();
if (@file_exists($file)) {
$filesys = preg_replace("/", "\\", $file);
$delete = @system("del $filesys");
clearstatcache();
if (@file_exists($file)) {
$delete = @chmod($file, 0775);
$delete = @unlink($file);
$delete = @system("del $filesys");
}
}

Use str_replace, or add delimiters to pattern if you really need preg_replace.
str_replace如果确实需要，请使用，或向模式添加分隔符preg_replace。
$filesys = str_replace("/", "\\", $file);
OR
或者
$filesys = preg_replace("~/~", "\\", $file);
