[SOLVED] help with arrays

[anatak]

Hello I am banging my head against some array stuff.

 

can someone explain how the syntax works to run through an array ?

 

I have an array $content and in that array is an index $cat_id

 

but I have no idea what the =>$category means

 

Can anyone explain or give me a link to a clear basic tutorial ?

I looked a the php page of array functions but I got lost there.

 

foreach ($content as $cat_id=>$category){

}

 

kind regards

Hi!

I give you two examples:

You got an array like that:

<?php
$arr[0] = 'hello';
$arr[2] = 'foo';
$arr[1] = 'world';
$arr[3] = 'bar';

foreach ($arr as $index => $value) {
	echo "$index => $value<br>\n";
}
?>

You see... the result is the same as you'r definition:

0 => hello
2 => foo
1 => world
3 => bar

 

Now the second example:

<?php
$arr['hello'] = 'world';
$arr['foo'] = 'bar';

foreach ($arr as $index => $value) {
	echo "$index => $value<br>\n";
}
?>

You also get the index and the value:

hello => world
foo => bar

 

I think now you know what $index => $value means

thanks for clarifying this.
