I am recieveing the following parse error:
Parse error: syntax error, unexpected '(', expecting ',' or ';' in H:\Programs\USBWebserver v8.5\8.5\root\oopforum\func\register.class.php on line 7
which relates to the following line of code in my class:
private $random_name = rand(1000,9999).rand(1000,9999).rand(1000,9999).rand(1000,9999);
I can not see why this line of code would cause a parse error?
Here is some surrounding code:
class register{
public $post_data = array();
private $dbh;
private $allowed_type = array('image/jpeg','image/png','image/gif');
private $random_name = rand(1000,9999).rand(1000,9999).rand(1000,9999).rand(1000,9999);
private $path = 'img/thumb_/'.$random_name. $_FILES['file']['name'];
private $max_width = 4040;
private $max_height = 4040;
private $max_size = 5242880;
private $temp_dir = $_FILES['file']['tmp_name'];
private $image_type = $_FILES['file']['type'];
private $image_size = $_FILES['file']['size'];
private $image_name = $_FILES['file']['name'];
private $image_dimensions = getimagesize($temp_dir);
private $image_width = $image_dimensions[0]; // Image width
private $image_height = $image_dimensions[1]; // Image height
private $error = array();
public function __construct($post_data, PDO $dbh){
$this->post_data = array_map('trim', $post_data);
$this->dbh = $dbh;
}
}
What is causing the parse error?
If the PHP code contains a syntax error, the PHP parser cannot interpret the code and stops working. For example, a syntax error can be a forgotten quotation mark, a missing semicolon at the end of a line, missing parenthesis, or extra characters.
Syntax Error – This error is caused by an error in the PHP structure when a character is missing or added that shouldn't be there. Unexpected – This means the code is missing a character and PHP reaches the end of the file without finding what it's looking for.
You can't initialize member variables to anything that is not static, and you're trying to call a function.
From the manual:
This declaration may include an initialization, but this initialization must be a constant value--that is, it must be able to be evaluated at compile time and must not depend on run-time information in order to be evaluated.
The workaround is to set your variable in the constructor:
private $random_name;
public function __construct() {
$this->random_name = rand(1000,9999).rand(1000,9999).rand(1000,9999).rand(1000,9999);
}
You can't do this:
private $image_dimensions = getimagesize($temp_dir);
Functions, variables, and anything else not static can't be called to set class variables.
