[PHP-DEV] PHP 4.0 Bug #7548 Updated: Database links and result sets seem to not be properly returned. From: tonym <email protected>

Description: Database links and result sets seem to not be properly returned.

Problem solved.

Apparently the following syntax cannot be used:

   $db = mysql_pconnect("server","user","pw") || die("error");

Check for success must be as follows:

   $db = mysql_pconnect("server","user","pw");
   if (! $db) { die("error"); }

Is this correct parsing for php?

Database links and result sets seem to not be properly returned.

Heavily edited script:

$db = mysql_pconnect("server","user","pw") || die "Couldn't connect to db!";
  // or, $db = mysql_connect( ... )

// the following works:
$result = mysql_list_dbs();
$x = mysql_num_rows( $result );
for ($i = 0; $i < x; $i++) {
  echo "table found: " . mysql_table_name($result, $i) . "<br>";
}

// the following does not:
$result = mysql_list_dbs( $db ); // give warning "not a valid MySQL link"
$x = mysql_num_rows( $result ); // give warning "not a valid MySQL result resource"

// the following works:
$result = mysql_query("INSERT INTO users (id, name) VALUES (10, 'fred')");

// the following does not:
$result = mysql_query("SELECT name FROM users")
    || die (Query failed); // die() not called
while ($row = mysql_fetch_row( $result )) { // give warning "not a valid MySQL result resource"
    <do something> // this line is never reached
}

// the following also does not work:
$result = mysql_query("SELECT 1 + 1 as total")
    || die (Query failed); // die() not called
$total = mysql_fetch_row( $result ); // give warning "not a valid MySQL result resource"
