illegal offset question

[ballhogjoni]

I have an illegal offset warning do to this  foreach loop:

 

foreach($aAvailableMonthsDates as $key=>$sStartDate){
$aAvailableMonths[$sStartDate] = date("F - Y", strtotime($sStartDate));
}

 

if I add single quotes around the index in the $aAvailableMonths array the warning goes away. My question is if I do that will it affect the actual value if the $sStartDate. What I mean is will the index now be a string that equals $sStartDate or will it actually be the value of the $sStartDate variable?

 

IE, can I do this with out any problems occuring:

foreach($aAvailableMonthsDates as $key=>$sStartDate){
$aAvailableMonths['$sStartDate'] = date("F - Y", strtotime($sStartDate));
}

using single quote it will treat it as string. and might not be the correct for logic.

can I use double quotes then?

Are you sure you don't want this instead?

foreach($aAvailableMonthsDates as $key=>$sStartDate){
$aAvailableMonths[$key] = date("F - Y", strtotime($sStartDate));
}

Yep, someone else wrote the code, it works, I just don't want to change anything like that.
