adding to an array 1

[jimoblak]

Here's a dumb question but I can't get this to work for some reason...

Suppose my array is:
$fruits=array(apples,oranges,bananas);

How do I add more fruits (plums, grapes, etc) to the array?

If you don't care about the index just do...

$fruits[] = "plums";
$fruits[] = "grapes";

etc.

My problem was how I was handling this in a session (a single quote was the thorn in my side). I am adding items to a session array based on URL GET's (example:

http://localhost/add_item.php?addfruit=plums).

The following will work if anyone stumbles on to this thread to ask the same question...

<?php
session_start();
if (!$PHPSESSID) {
session_register('fruits');
}

if (!$_SESSION[fruits]) {
session_register('fruits');
}

if (isset($_GET[addfruit])) {
$_SESSION[fruits][]=$_GET[addfruit];
}

Careful with that code...

http://www.php.net/manual/en/function.session-register.php

Notice specifically the third Caution box...

$_SESSION and session_register are not meant to be used together.

The new style would be more like so...

session_start();
if (!$PHPSESSID) {
$_SESSION[&quot;fruits&quot;]=array();
}

if (!isset($_SESSION[&quot;fruits&quot;])) {
$_SESSION[&quot;fruits&quot;]=array();
}

if (isset($_GET[&quot;addfruit&quot;])) {
$_SESSION[&quot;fruits&quot;][]=$_GET[&quot;addfruit&quot;];
}


Hope that helps.

(and the convention is to use the quotes in those array indices, I believe you can do single or double... sometimes you can get away with not using them, but on upgrades or platform switches your results may go wacky)
