[SOLVED] Comparing Array Keys

[KresentPhresh]

Alright... So I'm still working with the same old array set I posted about a few days ago. (If you're unaware, I'm querying a database table with two fields - Timestamps and ID, and returning all timestamps that match a certain ID, so what I end up with is an array of ##-##-#### ##:##:## timestamps in DATETIME format.) The problem I had before was grouping the results into an array by date where the date was the key and the number of rows matching that date were the values so I could parse something like;

 

4 Clicks on 07/29/2009

5 Clicks on 07/30/2009

Etc.

 

This is working correctly, but now for the purpose of graphing the data, I need to be able to check something first.

 

Basically, I just need to figure out how to check EVERY key in the array to see if they're all identical (that way if ALL the dates are the same, I can make a different graph that charts them on a 24-hour timeline) but I'm not really sure how I would go about handling such an operation. If anyone has any expertise they could lend, it would be much appreciated.

 

Many thanks.

#Just use array_keys on the array... if it has a sizeof() > 1 there are different keys
$arr1 = array('key1'=>'Val1','key1'=>'Val1','key3'=>'Val1','key1'=>'Val1','key2'=>'Val1');
$test = array_keys($arr1);
echo "The array has ".sizeof($test)." array keys";

echo "<br />";

$arr2 = array('key1'=>'Val1','key1'=>'Val1','key1'=>'Val1','key1'=>'Val1','key1'=>'Val1');
$test2 = array_keys($arr2);
echo "The array has ".sizeof($test2)." array keys";

Ahhhhh, yes! I was looking at that function but wasn't sure if it would do what I needed, but yeah, checking the size of the result.... PERFECT! You rule, sir!
