Let's say I have an array like this:

array(
name=>'sam',
age=>'22',
weight=>'222'
)

How can I update the name element in the array? to set it to 'John' for example....

<?
// Original data
$myArray = array(
  "name" => "sam",
  "age" => "22",
  "weight" => "222"
);

// Change just the name to "John"
$myArray["name"] = "John";
?>

The online manual might be helpful for these sorts of questions.  For example, if you wanted to know if "sam" was in the array, you could use in_array()
http://us.php.net/manual/en/function.in-array.php

if (in_array('sam', $my_array)) echo "We found Sam!";

The complete list of array functions is here:
