PHP 5.3.10 vs PHP 5.5.3语法错误意外'['

Question

Is it possible that this PHP code line

if ($this->greatestId()["num_rows"] > 0)

works in PHP 5.5 and returns an error in 5.3??

PHP Parse error:  syntax error, unexpected '[' in /var/www/app/AppDAO.php on line 43

How can I change it to work under PHP 5.3?

Answer 1

You cant use like this if ($this->greatestId()["num_rows"] > 0) in PHP 5.3 ver use below code.

$var = $this->greatestId();
if ($var["num_rows"] > 0){
  // your code
}
