如何解决while循环中if语句混乱
| 在过去的四天内，这一直是我的不懈努力。我真的希望能够解决这个问题，而不必在这里询问，因为它包含很多代码，但是我恐怕已经尝试并尝试减少问题的发生，就像我一样。追着我的尾巴。我已经尽我所能消除了很多代码-我可能已经消除了比我应该轻松了解正在发生的事情多得多的代码，请随时提出澄清。 内容提要： 我正在从Google日历中提取日历供稿，并填充自己的日历。我的日历添加了一些功能，其中有一个“时间轴事件”数据库，该数据库类似于从常规事件发生一定天数（DaysFromEvent
StartTime + DaysFromEvent
if((int)$Feed->totalResults>0) { //checking if at least one event is there in this date range
foreach ($Feed as $event) { //iterating through all events and pulling all the info to assign the variables below.
$UserID= \"42\";
$eventDatabase = \"events\";
//Setting startDate and startTime and endDate and endTime
$startDate = $event->when[0]->startTime;
$date = strtotime($startDate);
$startDate = date(\'Y-m-d H:i:s\',$date);
$startArray = explode(\' \',$startDate);
$startTime = $startArray[1];

//We are seeing if the Event is already in the database by looking for the googleID
$query = \"SELECT * FROM \".$eventDatabase. \" WHERE GoogleID=\'$GoogleID\'\";
$result = MysqL_query($query);
$row = MysqL_fetch_array($result,MysqL_ASSOC);
//This loop UPDATES events if ModifiedInGoogle string is different than what is already in the database
if($ModifiedInGoogle != $row[\'ModifiedInGoogle\']){
//Variables for modifying the timeline start time

//Query to select the timeline events that have the same ParentEvenID-this is where everything seems to start falling apart...

$tempDaysFromEvent = $row[\'DaysFromEvent\'];
$tempStartDate = $row[\'StartDate\'];
//THIS LINE IS NOT ECHOING
echo \"EventID: \".$tempEventID.\",Start Date: \".$tempStartDate.\",Days From Event: \".$tempDaysFromEvent.\",Parent Event ID: \".$row[\'ParentEventID\'].\"<br>\";
//IF STARTDATE IS DIFFERENT FROM HOW IT USED TO BE,UPDATE IT.
list($year,$month,$day) = explode(\"-\",$tempStartDate);
$tempStartDate = $tempEndDate = date(\"Y-m-d\",mktime (0,$day+$tempDaysFromEvent,$year));

} //Closes While loop
} //This closes the update if modified if statement
//This loop adds NEW EVENTS
if (!MysqL_num_rows($result)) {
