What's wrong with this???

tiffcrader

I'm just trying to do something VERY simple. I'm trying to understand multi-dimensional arrays and by doing so just trying to print something. Here's the code:

print ("is $family_members[1][weight]");

When I try to view this I get a parse error????

Any suggestions???

Try...

print ("is $family_members[1]['weight']");

when using assosiative arrays the key must be a string and therefore needs the single quotes

this is what it showed up as

have you assigned $family_members[1]['weight']?

that example could play out like this:

// About Brian Moore
$family_members[1] = array('fname' => 'Brian' , 'lname' => 'Moore' , 'weight' => '???' , 'age' => '22' , 'height' => '6' , 'hair' => 'blonde');

// output
echo "I love $family_members[1]['fname']<br>";
echo "He is $family_members[1]['height'] feet tall<br>";
echo "$family_members[1]['fname'] $family_members[1]['lname']";
echo " is $family[1]['age'] and has $family_members[1]['hair'] hair<br>";
echo "is $family_members[1]['weight']";

print ("is $family_members[1][weight]");

Try:

echo 'is ' . $family_members[1]['weight'];

What output does var_dump($family_members) give you?

I could be wrong, it has happened before and I'm going into dusty corner of my memory but you may have to put {} around the variable so php realizes that it is a two dimensional array.

{$family_members[1]['weight']}

Give that a try.

echo " is $family[1]['age'] and has $family_members[1]['hair'] hair<br>";
echo "is $family_members[1]['weight']";

[/B]

I get this

I love Array['fname']
He is Array['height'] feet tall
Array['fname'] Array['lname'] is ['age'] and has Array['hair'] hair
is Array['weight']

However if I put {} around the variables like this:

// About Brian Moore
$family_members[1] = array('fname' => 'Brian' , 'lname' => 'Moore' , 'weight' => '???' , 'age' => '22' , 'height' => '6' , 'hair' => 'blonde');

// output
echo "I love {$family_members[1]['fname']}<br>";
echo "He is {$family_members[1]['height']} feet tall<br>";
echo "{$family_members[1]['fname']} {$family_members[1]['lname']}";
echo " is {$family[1]['age']} and has {$family_members[1]['hair']} hair<br>";
echo "is {$family_members[1]['weight']}";

I get as an output:

I love Brian
He is 6 feet tall
Brian Moore is and has blonde hair
is ???

Just wanted to post a little clarification from my above one that just said use the {}.

hi...
I want to use an array to store 10 occurences of 4 different variables, basically because I want to link them..
so:

$stuff[1] = array('a' => 'tick', 'b' => 'firstname', 'c' => 'lastname', 'd' => 'middlename');

This brings back a parse error..
can someone please help me figure out what I have done wrong... looks very similar to the above egs?

Then I need to figure out how to get this data from the input boxes on the screen...

Would I be better to hardcode 4 arrays of size 10 and use the counter as the link??

Thanks for any advice/pointers!
