循环没有运行我想要它运行的方式

不确定我是否可以这样做......

好吧我现在在这里运行循环来检查学生#和电子邮件我使用$ error_check = 0和$ error_check ++来考虑是否有错误。如果有,那么将显示一个错误,并且会将某些内容打印到error.log中,如果没有,那么类似.txt文件的内容就会打印出来并打印内容

但我刚刚意识到,如果我的.txt文件的第一行出错,或者如果我的.txt文件中的第二行内容出现错误,那么脚本将只能正常运行,然后打印正确的消息输出第一行内容,错误信息也将打印出来。

但当然我希望脚本能够运行,即使第一行内容没有错误而其他一些行有错误,那么只会打印错误信息。

我认为应该是关于我将脚本放在循环中的地方,但不知怎的,我继续阅读我的脚本,不知道我应该改变什么......

else  //else file exist then.......else #1
{
    $fileContents = file("./courses/" . $_GET["filename"]);  //calls out the file into $fileContents[] array....so $fileContents[0] is like the first row of the contents

$datePrinted = false;  //setting a flag first so the date will be print only once when there's error..being used later in the foreach loop

$error_message = false;  //setting a flag so error message only show once and being used later in the foreach loop

$well_formed = false;  //another flag  to stop the looping message saying the file is correctly formed

$table = false;

$error_check = 0;

sort($fileContents);

foreach($fileContents as $row)  //the contents will be then seen as $row
{
    $column = preg_split("/,/", $row);  //splits the row by , and name each array as $column
    $error_log = fopen("./courses/path/error.log","a+") or die ("File can not be opened");  //creates/open an error.log file

    if(!(isEmailAddressWellFormed($column[3])) || !(isStudentNumberWellFormed($column[0])))  //two functions calls from page4.php using preg_match to check email and student# validation
    //if one of them do not validate the following will start
    {
        $error_check++;
        if(!$error_message)  //if this is false then the error message+link will show
        {
        echo "Errors have been found in " . $_GET['filename'] . "<br/><a href='./courses/path/error.log'>Click here for the log</a>";
        $error_message = true;  //since this is in a loop but doesn't need to print it out so many times so changing the value here to true so when this loop runs again if(!error_message) will not run again
        }
        if(!$datePrinted)  //works as how error_message works.  the date only print once by here
        {
        fwrite($error_log, date("F t, Y (h:i:s a)") . PHP_EOL);
        $datePrinted = true;
        }

        if(!(isEmailAddressWellFormed($column[3])))  //checks again if the email is not valid then print the follow to error.log
        {
        fwrite($error_log, "Improper email address from" . $_GET["filename"] . " :" . PHP_EOL);
        fwrite($error_log, "$column[2] $column[1] $column[3]" . PHP_EOL);
        }
        if(!(isStudentNumberWellFormed($column[0])))  //checks again if the student # is not valid then print the follow to error.log
        {
        fwrite($error_log, "Improper student numbers from" . $_GET["filename"] . " :" . PHP_EOL);
        fwrite($error_log, "$column[2] $column[1] $column[0]" . PHP_EOL . "\n");            
        }
    }



    elseif($error_check == 0)
    {

        if(!$well_formed)
        {
            echo "<h1 style='color: red'>" . $_GET["filename"] . " is well formed.</h1>";
            echo "<table>";

            $well_formed = true;
        }

                echo $column[0];
                echo $column[1];
                echo $column[2];
                echo $column[3];

    }

}//closing foreach
        fwrite($error_log, str_repeat("-",80) . PHP_EOL);  //puts a line to separate the next error but each time the page runs this line will print even if there's no error
        fclose($error_log);

                    if(!$table)
        {
            echo "</table>";
            $table = true;
        }

}//closing else #1

事先感谢人们的帮助......谢谢....

我添加了

$row = $column[0] . $column[1] . $column[2] . $column[3];
在preg_split之后的foreach开头,然后在底部,我改为...

    elseif($error_check == 0)
    {

        $row.=$row;
    }

}//closing foreach
        fwrite($error_log, str_repeat("-",80) . PHP_EOL);  //puts a line to separate the next error but each time the page runs this line will print even if there's no error
        fclose($error_log);

    if($error_check == 0)
        {

            echo "<h1 style='color: red'>" . $_GET["filename"] . " is well formed.</h1>";
            echo "<table>";
            echo $row;
            echo "</table>";

        }

}//closing else #1

?>

但现在它只打印出内容O.o中的第二行。目前只有三行内容供测试....我在这里遗漏了一些小事吗?
