Question

我有一个要求，我将每个页面访问和活动记录到csv日志文件中。我该怎么写才能首次写入标题，而不是每次都写。

fputcsv($fh1, array(date,id1,page,id2,request,ip));     
fputcsv($fh1, array($date,$mid,$page,$aid,$request,$ip));

第一个数组只应为特定的日期日志文件写入一次。请建议。

我希望您在下载CSV时尝试使用标题排列记录。如果是，那么请看下面这个例子，我在小例子中显示它在Drupal中工作 -

<?php

function getUsersDetails(){
    $csv_output = '';
    $all_users_entry = db_query("SELECT * FROM users");
    while($users = db_fetch_object($all_users_entry)){//suppose these fname,lname etc are column name of your table.
        $fname = $users->fname;
        $lname = $users->lname;
        $date = $users->joining_date;
        $role = $users->role;
        $location = $users->location;
        $csv_output .= "\"".$fname."\"".","."\"".$lname ."\"".","."\"".$date."\"".","."\"".$role."\"".","."\"".$location."\""."\r";
    }
    return $csv_output;
}

function download_details(){
    $csv_output = '';
    $csv_output .= "First Name,Last name,Member Since,Role,Place\n";
    $csv_output .= getUsersDetails();
    header('Content-type: text/csv');
    header('Content-Disposition: attachment; filename="Usera_Details.csv"');
    print $csv_output;
    exit;
}
?>

现在您可以从任何地方调用此函数download_details（），您将在下载的CSV中拥有用户表详细信息

当你看到这个时，你会踢自己......

if (!file_exists('log.csv'))
{
    // Make the file & Write the header
}
// Write the log entry.

使用php将标题写入csv
