Question

I have a variable:

$testingAllDay = $event->when[0]->startTime;

This variable will be this format if it is “All Day”:

2011-06-30

It will be this format if it is not “All Day”:

2011-07-08T12:00:00.000-05:00

I’m wanting to do something like:

if ($testingAllDay does not contain "T"){
   $AllDay = 1;
   } else {
   $AllDay = 0;
}

Do I need to use a strstr() here, or is there another function that does this? Thanks!

Answer 1

One option is to use strpos to see if the ‘T’ character is present in the string as follows:

if (strpos($testingAllDay, 'T') !== false) {
    // 'T' was present in $testingAllDay
}

That said, it would probably be faster/more efficient (although no doubt meaninglessly so) to use strlen in this case, as according to your example, the time-free field will always be 10 characters long.

For example:

if(strlen($testingAllDay) > 10) {
    // 'T' was present in $testingAllDay
}
