小编k0p*_*kus的帖子

我按照以下步骤操作:

1. $ cd $Home/projects/
2. $ git clone https://github.com/someUser/someRepo.git

3. $ git add .

   fatal: Not a git repository (or any of the parent directories): .git

4. $ git commit -m "first commit"

   fatal: Not a git repository (or any of the parent directories): .git

我想要做的基础是检查用户值.

如果它们返回true并返回页面,否则返回false并打印空值.

$query = sprintf("SELECT * from Users where username = ? and password = ?");
$params1 = array( $username, $password);
$stmt = sqlsrv_query($conn, $query, $params1);
if ($stmt === false) 
{
    die(print_r(sqlsrv_errors(), true));
}

$Users = array();

while ($row = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC)) {
    $username1 = $row['username'];
    $password1= $row['password'];
}


$Users["username"] = $username1;
$Users["password"] = $password1;

//echo json_encode($Users);
echo "you are here";

if ($username1==null)
{
    return false;
    echo "null values";
}
else {
    return true;
    if (!empty($_SERVER['HTTP_REFERER'])) …

我想将文件上传到给定的文件夹。

<?php
$folder = "upload/";
if (is_uploaded_file($HTTP_POST_FILES['filename']['tmp_name']))  {   
    if (move_uploaded_file($HTTP_POST_FILES['filename']['tmp_name'], $folder.$HTTP_POST_FILES['filename']['name'])) {
         echo "File uploaded";
    } else {
         echo "File not moved to destination folder. Check permissions";
    };
} else {s
     echo "File is not uploaded";
}; 
?>

错误是：

注意：未定义的变量：第3行的C：\ wamp \ www \ sdg \ import \ ips.php中的HTTP_POST_FILES

我试图在{ }使用之间提取价值

"\\(\\{[^}]+\\}\\)" 

java中的正则表达式.我的意见是

String text = "Hi this is {text to be extracted}."

我希望输出为

"text to be extracted" 

但是那个正则表达式没有用.

我正在尝试一个循环脚本,如果可能的话,每个循环并行运行.

#!/bin/bash

for ip in $(cat ./IPs); do
ping -n -c 2 -W 1 ${ip} >> Results/${ip}.log
done

最终,我想在循环中放置我需要的任何东西,并让它进行多处理.我试图通过其他示例,但似乎无法让它按预期工作.我已经parallel安装了,如果这是一个选项.

我希望每个数字后面只有一个逗号,并删除多个逗号,这些逗号位于数字之间:

例如有数字

73663 ,,,,,, 662633,6666777 ,,,,,,, 56,7 ,,, 77788,665,654446

删除过多的逗号我应该有

73663,662633,6666777,56,7,77788,665,654446

我怎样才能在JavaScript中执行此操作？
