Question

My PHP code works well in connecting remote windows system mysql database and returns the output. But, when I’m using the same to connect remote linux system’s mysql database, I got the following error:

“mysql_query() expects parameter 2 to be resource, boolean given in
C:\wamp\www\mysqldb.php on line 88”

That line 88 have the following content “$this->resultQur =
mysql_query($query, $this->connID);”

Help me to solve this.

yes. The resource is null in this case. But the same works in windows mysql connection. I got the error only in linux. Need to do any change for linux environment?

While putting “print mysql_error();” i got the following error

“A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.”

Answer 1

The resource you’re providing comes from a mysql_connect and that did not succeed!

• Put error reporting on
• Build some basic error handling in your script
• Do not use mysql_* but mysqli_* or even better PDO with parameter binding
