Most times you can get a reference to an object using document.getElementById("myID"). However, there are certain situations where an alternate method is required. For example, if there is no ID because the object you are trying to retrieve isn't an HTML element and perhaps the name of the object isn't known until run-time.

If the object name is known at design-time, you can easily refer to the object using dot notation. Dot notation is a way to traverse the Document Object Model (DOM) to find the object you're looking for. For example:
CODE
document.formName.fieldName.value

What you may not be aware of is that you can also refer to objects like you would with an associative array:
CODE
document.formName["fieldName"].value
Or:

The OSX PHP is located in /usr/bin/php and /usr/bin is in PATH variable by default.

One way to make OSX use MAMP PHP is to add /Applications/MAMP/bin/php/php5.x.x/bin/ to your PATH variable (before /usr/bin):

Simply edit ~/.profile (ie. open Terminal.app, type vim ~/.profile) and add the following line to end of the file:

export PATH=/Applications/MAMP/bin/php/php5.x.x/bin/:$PATH
Note that you should replace xs in php5.x.x with the MAMP Pro PHP version
