PHP文件无法输入部分代码
作者：互联网
这是我的php文件中的一个函数,用于提供我的Android应用程序的请求.
function checkin($DB, $TechID, $ClientID, $SiteID){
$dbConnection = mysql_connect($DB['server'], $DB['loginName'], $DB['password']);
if(!$dbConnection){
die('Error! ' . mysql_error());
}
mysql_select_db($DB['database'], $dbConnection);
$file2 = "C:/wamp/www/file2.txt";
$data2 = "ClientID:".$ClientID." TechID:".$TechID." SiteID:".$SiteID;
file_put_contents($file2, $data2);
$result1 = mysql_query("SELECT COUNT(*) FROM Log") or die('Error! ' . mysql_error());
$query = "SELECT `Type` FROM `Log` WHERE `TechID` = '".$TechID."' ORDER BY LogTime DESC LIMIT 1";
$file5 = "C:/wamp/www/file5.txt";
file_put_contents($file5, $query);
$result2 = mysql_query($query) or die('Error! ' . mysql_error());
while($row1 = mysql_fetch_array($result1)){
$count = $row1['COUNT(*)'];
$file3 = "C:/wamp/www/file3.txt";
$data3 = "ClientID:".$ClientID." TechID:".$TechID." SiteID:".$SiteID." Count:".$count;
file_put_contents($file3, $data3);
while($row2 = mysql_fetch_array($result2)){
$file4 = "C:/wamp/www/file4.txt";
$data3 = "ClientID:".$ClientID." TechID:".$TechID." SiteID:".$SiteID." Count:".$count;
file_put_contents($file4, $data3);
/*if($row2['Type']!="Checkin"){
$count = $count+1;
$Time = date('Y/m/d H:i');
mysql_query("INSERT INTO Log (LogID, TechID, ClientID, SiteID, LogTime, Type)
VALUES (".$count.", ".$TechID.", ".$ClientID.", ".$SiteID.", ".$Time.", Checkin)");
}else{
$query2 = "SELECT TechEmail FROM Tech WHERE TechID=".$TechID;
$result3 = mysql_query($query2) or die('Error! ' . mysql_error());
$subject = "Please check out";
$message = "You have forgot to logout from the last site, please check out manually";
$from = "devadmin@uniserveit.com";
$header = "Form:".$from;
while($row3 = mysql_fetch_array($result3)){
mail($row3['TechEmail'], $subject, $message, $header);
}
}*/
}
}
}
你可以看到我隐藏了一些代码,因为我正在调试它,我创建了一些文件只是为了看看代码的哪一部分无法执行.我发现程序无法进入应该创建file4的区域.我已经找到了问题可能来自$query,当它执行时,某些时候mysql将响应“未知表状态：TABLE_TYPE”,我无法理解为什么.
解决方法:
正如上面的评论中所写,你应该分而治之以使你的生活更轻松(特别是当你在那个大型函数中使用它时编写代码时).这确实很简单：
function file_put($number, $data)
{
$path = sprintf("C:/temp/wamp/www/file%d.txt", $number);
file_put_contents($path, $data);
}
例如,这只是替换你需要一个(编号)文件的许多重复行,你放入一些字符串.
但是你也可以用更复杂的东西来做这件事,比如数据库操作.您可能希望将错误处理移出您的视线,并在需要时注意连接到数据库,并采用更灵活的方式来获取数据.这可以通过将(轻度弃用的)mysql_ *函数移动到它自己的一个或两个类中来完成,这样它就会脱离你的视线.这将使它的使用更容易(我先说明)：
// Create your database object to use it later on:
$config = array(
'server' => 'localhost',
'name' => 'root',
'password' => '',
'db' => 'test',
);
$db = new MySql($config);
我调用了数据库类MySql,因为它代表了mysql连接,它适用于旧的mysql扩展.您只需要将该数据库对象传递到您问题中的函数中.结合file_put函数,它看起来像这样：
function checkin(MySql $DB, $TechID, $ClientID, $SiteID)
{
$query = sprintf("SELECT `Type` FROM `Log` WHERE `TechID` = '%d' ORDER BY LogTime DESC LIMIT 1", $TechID);
file_put(5, $query);
$result1 = $DB->query("SELECT COUNT(*) FROM Log");
$result2 = $DB->query($query);
foreach ($result1 as $row1) {
list($count) = $row1;
$data = "ClientID:$ClientID TechID:$TechID SiteID:$SiteID Count:$count"
file_put(3, $data);
foreach ($result2 as $row2) {
file_put(4, $data);
}
}
}
checkin函数仍然很大(已经有12行代码),但是比第一个版本短得多,因为它委派了编写文件和访问数据库的工作.我希望这个演示很有用.以下是完整的代码示例：
