Fatal error: Function name must be a string with Anonymous function

Question

I am finding myself in a bit of a problem. I have two anonymous functions and one calls the other. But when the function $fCompleteDate is called within the function $fFindAndCreateDate

I get the fatal error of:

Function name must be a string.

The function $fFindAndCreateDate is called later on in the script.

I have literally no idea what the problem is.

$fCompleteDate = function($sDate)
{
  $sDate = str_replace('/', '-', $sDate);
  return str_repeat('01-', max(0, 2 - substr_count($sDate, '-'))) . $sDate;
};

$fFindAndCreateDate = function($aStruct)
{
  $aDateStructNames = array('', 'Remark', 'Formatted', 'Extra');
  foreach($aDateStructNames as $sDateStructName)
  {
    echo $fCompleteDate('2001');
    echo  'a : '. $fCompleteDate($aStruct['startDate'.$sDateStructName]);
    echo  'b : '. $fCompleteDate($aStruct['endDate'.$sDateStructName]);
  }
};

This is not valid PHP function. JS function and PHP function both are different. — Ravi Hirani

I dont know why PHP called this way as Anonymous while nothing is anonymous in this kind of declaration. — Ravi Hirani

I see that you use Anonymous functions so I updated my answer.

You need to specify that the second function use the first one like this:

$fFindAndCreateDate = function($aStruct) use ($fCompleteDate) {
 ....
}

Why is the function $fFindAndCreateDate called correctly then?

@KevinKamer Sorry for that, I updated my answer for Anonymous functions. You only need to add use ($fCompleteDate) to second function.
