Functions - where do they go?

[Anon]

If I create a function where do I put it in order for other PHP programs to be able to use it within their code?

Sorry if this is something I should already know..... 🙂

Cheers

Make funcitons anywhere in any file

One simple example. Hope this may help u.

Eg If u have made function one() in filename general.php3

and u want to include this function in index.php3 file

Then in index.php3 file
first include general.php3 and just type function one() anywhere . This will do whatever u have written there in this function in file general.php3

create a file where you will store all your funcitons. I like to call mine

functions.php

now, for other files that might need functions that you defined in the functions.php file, simply put:

include( 'functions.php' );

at the beginning of the file.
hope that helps.

Ok, I have one problem with this.

Say, this function needs variables passed to it, i.e

function dropdown($table, $name) {
include "admin/lib.mysql.php";
$query="SELECT * FROM $table ORDER BY $name ASC;";
$result=mysql_db_query($dbname, $query, $dblink);
if ($row=mysql_fetch_array($result)) {
//print "<select>";
do {
printf("<option value=\"%s\">%s</option>\n", $row["$name"], $row["$name"]);
} while ($row = mysql_fetch_array($result));
}
}

The moment I have this function is say lib.mysql.php, and I call it from another file, called branch.php as follows:
? print dropdown(branch,b_name); ?>, and lib.mysql.php is included in branch.php, it tells me it cannot redeclare dropdown() in lib.mysql.php.

Why not?
