Maximum execution time of 30 seconds exceeded in - php

Question

I'm learning php MVC and in my display model i got this fatal error
Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\kowab\app\models\display.php on line 36
line 36 is $data = mysql_fetch_array($sql);

Answer 1

To remove this error you have to increase max_execution_time in your php.ini. Afterwards you have to restart the apache.
Or you add ini_set('max_execution_time', x) at the top of your script.
But you should think about optimizing your query and code first.

Answer 2

Are you watching from the Arabic man's tutorials? (Ali Hamdi)
I experienced the same thing and I made my else statement of the display class this way:
else
{
$num = mysql_num_rows($sql);
while ($num > 0)
{
$data = mysql_fetch_array($sql);
$num--;
}
}
return $data;
}
}
?>
It didn't solve the problem, but it brought back the form at least. So I continued watching the rest of the tutorials and following him so that later I address that part. I have written him and awaiting for his response. as soon as he does, I'll get back to you with the solution.

Answer 3

Up your execution time by making your first line of code:
set_time_limit($x);
$x should be the maximum time in seconds for running the script. A value of 0 will let the script run infinitely.
http://us1.php.net/set_time_limit
NOTE: It is weird that you hit a 30 second time limit on line 36, so you probably have a problem with your code that we can't identify, because you haven't posted it.

Answer 4

You can increase that time by looking for max_execution_time in php.ini but before that you need to know what cause this issue. Check your query there might be some loop or it returns a huge data

Answer 5

set_time_limit($seconds);
Per the docs. If you pass a value of 0 for $seconds there will be no time limit.

Answer 6

here is my model
// display
class display extends awebarts {
public function __construct($tablename) {
$this->tablename= $tablename;
$this->connectToDb();
$this->getData();
$this->close();
}
function getData() {
$query = "SELECT * FROM $this->tablename ORDER BY `ID` DESC LIMIT 1";
if(!$sql = mysql_query($query))
{
throw new Exception (mysql_error());
}
else {
$num= mysql_num_rows($sql);
while($num >0)
{
$data= mysql_fetch_array($sql);
}
}
return $data;
}
}
?>``
