Question

我正在我的大学里开展一个项目，那就是为我的大学开发一个类似hackerrank的在线自动编程网站。现在，为了编译代码，我使用了sphere引擎提供的API。 API将输出作为字符串返回，然后将其存储到文件中。然后，我使用先前定义的输出文件来比较该文件，并相应地检查代码是对还是错。现在的问题是例如。如果输出如下：

Hello World

该字符串在Hello WorldHello WorldHwllo World中写入文件。我正在使用PHP将文本写入文件。

有没有办法将字符串写入文件？任何其他替代方法也将受到赞赏。

谢谢。

修改

例如，如果代码：

#include<iotsream>
using namespace std;
int main()
{
 int i;
 for(i=0;i<3;i++)
 {
 cout<<"Hello World\n";
 }
 return 0;
}

此代码的输出应为

Hello World

当我显示存储在PHP数组$ data ['output']中的字符串时，它正常显示，但是当我将此字符串写入文件时，它将被存储在一行中。我希望将字符串存储在不同的行中。

由于这个原因，这个文件如果不等于包含不同行中字符串Hello World的模板输出文件。

EDIT 这是该文件的PHP代码，它将获取源代码和输入并将其发送到编译器并相应地接收它的输出。

你不能在php文档中用C语言编写。无论如何，这是写入文件的PHP代码。

<?php
$fp = fopen('file.name', 'a+');
fwrite($fp, 'Hello World'.PHP_EOL);
fclose($fp);
?>

使用PHP
