You need to use $style->setBinding(MS_STYLE_BINDING_SIZE, 'attribute') 
to bind the size to an attribute.

The PHP MapScript docs on the website haven't been updated with those 
new methods added in 5.0 yet so I have added a comment in the docs about 
them at:

http://mapserver.gis.umn.edu/docs/reference/phpmapscript-class/classes/styleobj



    int setBinding(const stylebinding, string value)
        Set the attribute binding for a specfiled style property. 
Returns true on success.

         Example:
            $oStyle->setbinding(MS_STYLE_BINDING_COLOR, "FIELD_NAME_COLOR");
            This would bind the color parameter with the data (ie will 
extract
            the value of the color from the field called "FIELD_NAME_COLOR"

    int removeBinding(const stylebinding)
         Remove the attribute binding for a specfiled style property. 
Returns true on success.
         Example:
            $oStyle->removebinding(MS_STYLE_BINDING_COLOR);
