What is the common mistake indicated by the error "Wrong parameter count for mysql_fetch_row()" in PHP?

The error "Wrong parameter count for mysql_fetch_row()" in PHP indicates that the function mysql_fetch_row() is being called with the wrong number of parameters. This function should be called with a single parameter, which is the result resource returned by a query execution. To fix this issue, make sure to pass the correct parameter to mysql_fetch_row().

// Correct usage of mysql_fetch_row() function
$result = mysql_query("SELECT * FROM table_name");
$row = mysql_fetch_row($result);
