I have a problem with some code (posted below), which I think I can
solve using a method similar to that found in Python:
if ($item in $potential_items) {
// do one thing
} else {
// do another
}
Is there something like this available in PHP?
Thank you,
Erik
If you wish to see more detail, I am trying to execute code that is very
similar to the following:
<?php
// in this example, $selected_users is an array of strings that have been
// selected from a multiple listbox in the previous instantiation of the
// page. I am redisplaying the form because the user has made a mistake,
// but trying to get those same strings to be "selected='yes'" in the new
// form.
$db = // mysql connection parameters
$sql = "SELECT id, name FROM users ORDER BY id ASC";
$result = mysql_query($sql, $db);
$c = 0; // this is a counter for the while loop
while ($row = mysql_fetch_assoc($result)) {
if ($row['id'] == $selected_users["$c"]) {
echo "<option value=\"{$row['id']}\"
selected=\"yes\">{$row['name']}</option>";
} else {
echo "<option value=\"{$row['id']}\">{$row['name']}</option>";
}
$c++; // bump up the counter for the next iteration of the fetched $row
}
?>
