escaping special charcters from a string

bar10der has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks,

For LDAP password authentication I need to escape any special characters that might be in the password.

I tried my best but so far can not find my way out. There is addslashes function in PHP which does the job. Is there any function similar to this in perl? Can some one give me an example, please

Thanks in advance for your help.

    According to this the php addslashes function does the following:

    string addslashes(string str)
    Escapes single quote, double quotes and backslash characters in a string with backslashes

    which you can do with:

    $string =~s/(['"\\])/\\$1/g;

    You might want to take a look at quotemeta. Try 'perldoc -f quotemeta' to get a quick overview.

    Update: added direct link to doc.

    Does the LDAP module you're using provide any way to handle the escaping for you? That's likely to be easier, faster, work better, and be more secure, since whoever wrote the LDAP module probably knows more about LDAP than you or I. :)
