将MySQL过程结果设置为PHP变量

Question

I am trying to set the two outputs from this MySQL stored procedure as PHP variables:

$result = mysql_query("CALL mst2('$q', @eset, @leng)");
if (!$result) {  
  die('Invalid query: ' . mysql_error());
} 

while($row = @mysql_fetch_assoc($result))
{
debug($row);

}
$eset = $row->{'@eset'};
$length= $row->{'@leng'};

The last two line are throwing an error Trying to get property of non-object . Does anybody know the proper way to do this?

Answer 1

mysql_fetch_object instead of mysql_fetch_assoc should fix your query up.

Secondly though you should really look at either using mysqli_ or pdo statements.

Links here:

Answer 2

Here's how I got it to work with mysql_query :

$result = mysql_query("CALL mst2('$q', @eset, @leng)");
$result = mysql_query("SELECT @eset, @leng");
if (!$result) {  
  die('Invalid query: ' . mysql_error());
} 

while($row = @mysql_fetch_object($result))
{
$eset = $row->{'@eset'};
}

right after the procedure I called a SELECT statement, then in the while loop, the $eset variable gets set properly.
