[SOLVED] Class could not be converted to string

[XpertWorlock]

Having a problem with a class, doesn't happen offline, but seems to occur when uploaded.

 

PHP offline 5.3

PHP online 5.2.9

 

Class code

class newsArticle{

function setDate($a){$this->date = unixToGregorian('j',$a);}
function setTitle($a){$this->title = $a;}
function setAuthor($a){$this->author = $a;}
function setDescription($a){$this->description = $a;}
function setID($a){$this->id = $a;}
}

 

calling of Class newsArticle

$news[$i] = new newsArticle();
	$news[$i]->setDate($row['date'] - (3600*5)); 
	$news[$i]->setTitle(mysql_real_escape_string($row['title']));
	$news[$i]->setAuthor($row['author']);
	$news[$i]->setDescription(mysql_real_escape_string($row['description']));
	$news[$i]->setID($row['id']);
	$i++;

 

 

The error I get is

 

Catchable fatal error: Object of class newsArticle could not be converted to string in ......

what line # does the error say and point out which line that is

[XpertWorlock]

$news[$i] = new newsArticle();

That error generally only occurs when you try to use the instance of the class as though it was a string, such as -

 

echo $news[$i];

 

Are you sure about the line where the error is occurring? Any chance that $i is an instance of a class?

 

Your posted code does not produce any php error under php5.2.11 (I don't have php5.2.9 to test with.)

If you do want to use an instance of a class like a string it's useful to utilize the __toString() magic method. Ex:

 

class someClass
{
     public function __toString()
     {
          return 'Some name';
     }
}

$in = new someClass;
echo $in; // Some name

if(mysql_num_rows($result) > 0)

{

$i=1;

while($row = mysql_fetch_array($result))

{

$news[$i] = new newsArticle();

$news[$i]->setDate($row['date'] - (3600*5)); //SET TO 5, WILL HAVE TO CONFIGURE

$news[$i]->setTitle(mysql_real_escape_string($row['title']));

$news[$i]->setAuthor($row['author']);

$news[$i]->setDescription(mysql_real_escape_string($row['description']));

$news[$i]->setID($row['id']);

$i++;

}

}

 

 

The $i is just to go through an array.  Like I said it works perfectly offline, doesn't want to work online though

[sasa]

try to declare $news as array before use it ($news=array()

[XpertWorlock]

Yeah that was my problem, I did not declare it before, although it worked offline, a safer programmer would have declared it before just to be safe.

 

I'll make sure I know that for next time.

 

Solution : Declare the array!
