  • PHP中MySql函数收集

    1.array mysql_fetch_assoc ( resource $result从结果集中取得一行作为关联数组

    说明:

       返回对应结果集的关联数组,并且继续移动内部数据指针。

    参数:result

        resource 型的结果集。此结果集来自对 mysql_query() 的调用。

    实例:

    <?php
     
    $conn  =  mysql_connect ( "localhost" ,  "mysql_user" ,  "mysql_password" );  
     
    if (! $conn ) {
        echo  "Unable to connect to DB: "  .  mysql_error ();
        exit;
    }
      
    if (! mysql_select_db ( "mydbname" )) { 
       mysql_colse($conn); echo
    "Unable to select mydbname: " . mysql_error (); exit; } $sql = "SELECT id as userid, fullname, userstatus    FROM sometable    WHERE userstatus = 1" ; $result = mysql_query ( $sql, $conn ); if (! $result ) { echo "Could not successfully run query ( $sql ) from DB: " . mysql_error (); exit; } if ( mysql_num_rows ( $result ) == 0 ) { echo "No rows found, nothing to print so am exiting" ; exit; } // While a row of data exists, put that row in $row as an associative array // Note: If you're expecting just one row, no need to use a loop // Note: If you put extract($row); inside the following loop, you'll // then create $userid, $fullname, and $userstatus while ( $row = mysql_fetch_assoc ( $result )) { echo $row [ "userid" ]; echo $row [ "fullname" ]; echo $row [ "userstatus" ]; } mysql_free_result ( $result ); ?>
