Only Variables should be Passed by Reference

[HoTDaWg]

hi there,

 

when i run calendar.php, its function ShowCalendar works fine as i echo its returned variable. However, when i require_once the file(calendar.php) and echo the function from another file it gives me the error:Only Variables Should be passed by Reference. It says the error is on line 25:

<?php
//here is the area around line 25
$dateformatted = $today['month'] . ' ' . $today['year'];

$days = array();   
    $query = "SELECT post_id,post_date FROM blog_posts";
    $result = mysqli_query($connection1,$query);
    while($row = mysqli_fetch_array($result)){
	if (settype(date('F Y',$row['post_date']),"string") == settype($dateformatted,"string")){#is the problem how I formatted this?
		array_push($days,date('j',$row['post_date']));
	}
}
?>

 

here is the full calendar.php:

//the script was merely changed to create a link that shows up everytime a post was created

function ShowCalendar(){
    //dont worry, this isnt my actual db username/pass hahaha
   //this is also NOT how i call upon my $connection variable, i just set it like this for testing purposes
    $connection1 = mysqli_connect('localhost','root','','blog'); 
    // Get key day informations. 
    // We need the first and last day of the month and the actual day
    $today    = getdate();
    $firstDay = getdate(mktime(0,0,0,$today['mon'],1,$today['year']));

            }
        if(in_array($actday,$days)){

    //Now display the rest of the month

       $fullstring .= '<tr>';

            $actday++;
            if ($actday == $today['mday']) {
                $class = ' class="actday"';
            } else {
                $class = '';
            }
            
            if ($actday <= $lastDay['mday']){
	        if(in_array($actday,$days)){

			}
            }
            else {
                $fullstring .= '<td> </td>';
            }
        }
        
        
        $fullstring .= '</tr>';
    }
    
    $fullstring .= '</table>';
return $fullstring;
}
?>

the area around line 25 basically finds all the posts in my database where the Month and Year are equal to the current month and year. It stores the days of such posts into an array and later on when the calendar is being created, it finds the appropriate days and puts a link around them.

 

again, the problem is the function does not work when im using it from another file.

 

any help would be greatly appreciated,

thanks,

change

    while($row = mysqli_fetch_array($result)){
      if (settype(date('F Y',$row['post_date']),"string") == settype($dateformatted,"string")){#is the problem how I formatted this?
         array_push($days,date('j',$row['post_date']));
      }

to

    while($row = mysqli_fetch_array($result)){
      $xxx = date('F Y',$row['post_date']);
      if (settype($xxx,"string") == settype($dateformatted,"string")){#is the problem how I formatted this?
         array_push($days,date('j',$row['post_date']));
      }
