It's Perl, not PERL and the bane of PHP is that it has a multitude of functions, which seem to do almost the same thing but not quite. By the last count there were almost 700 functions!

As an example there is:

• mysql_connect which is defined as mysql_connect ( [string $ server [, string $ username [, string $ password [, bool $ new_link [, int $ client_flags ]]]]] ); and
• mssql_connect which is defined as mssql_connect ( [string $servername [, string $username [, string $password [, bool $new_link]]]] )

and yes, you have odbc_connect and odbc_pconnect if you need persistent connections and the whole lot of mysqli_* improved functions ("i" for improved) and for the Postgres users there is of course pg_connect which unfortunately has a totally different syntax.

Perl has chosen not to go that way, but to provide a basic core of functions and core-modules extending the basic-functions and a multitude of modules which you can add when necessary. This keeps Perl as a language relatively small and clean, but allows for easy extension if and when necessary.

If you want to start coding in Perl, don't try to code PHP in Perl.

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
