Regex for checking folder name and file name

Question

I want to check the file name

The file or folder name should not contain \ /? % *: | "<>.

Could you suggest me a regex expression for use in preg_match ()?

Thanks.

Answer 1

It would be more efficient to use the strpbrk () function.

if (strpbrk($filename, "\\/?%*:|\"<>") === FALSE) { /* $filename is legal; doesn't contain illegal character. */ } else { /* $filename contains at least one illegal character. */ } 

Answer 2

A regular expression that matches your requirements: ^[^\\/?%*:|"<>\.]+$

Answer 3

 new RegExp('^[a-zA-Z--0-9_!]+$')

 new RegExp('^[^\\\\\/\?\%\*\:\|\"<>]+$')
