I'm having a little difficulty reading an api manual and applying it to php.

I've made an object:
$selector2 = new Selector();

as defined by this page of the API:
http://code.google.com/apis/adwords/...html#dateRange

And I want the type to be dateRange:
$selector2->dateRange...

Although I've tried a few different things, I can't figure out how to define max and min
http://code.google.com/apis/adwords/...DateRange.html
for that selector.

I have never used the Adwords API, but maybe it would be something like:

$dateRange = new DateRange();
$dateRange->min = '20110701';
$dateRange->max = '20110731';

$selector2 = new Selector();
$selector2->dateRange = $dateRange;

No, but you put me on the right track.

$selector->dateRange = new DateRange('20110101','20110105');

And for others looking for this answer, here's most the code:

$selector = new Selector();
$selector->fields = array('ExternalCustomerId', 'AccountDescriptiveName',
'PrimaryUserLogin', 'Date', 'Id', 'Name', 'Impressions', 'Clicks',
'Cost', 'AdNetworkType2');

// Create report definition.
$reportDefinition = new ReportDefinition();
$reportDefinition->reportName = 'dan_CrossClient-Complex-' . uniqid();

$reportDefinition->dateRangeType = 'CUSTOM_DATE';
$selector->dateRange = new DateRange('20110101','20110808');
$reportDefinition->reportType = 'CAMPAIGN_PERFORMANCE_REPORT';
$reportDefinition->downloadFormat = 'CSV';
$reportDefinition->selector = $selector;



If you have an EXPLANATION, just a little tidbit about OOP that it appears I don't know, I'd really appreciate it.
