[英]How do I add content in a new row to a txt file
Just use the PHP_EOL
(PHP end of line) constant that will create a new line. 只需使用PHP_EOL
(PHP行尾)常量即可创建新行。
This must be appended at the end of each line. 这必须附加在每行的末尾。
$file = fopen("myfile.txt", "a+");
fwrite($file, "hello".PHP_EOL);
// or...
fwrite($file, $myvar.PHP_EOL);
Alternatively, you could create your own, new, function: 另外,您可以创建自己的新功能:
function fwrite2($handle, string $string, $length = null, $newline = true) {
$string = $newline ? $string.PHP_EOL : $string;
if (isset($length)) {
fwrite($handle, $string, $length);
} else {
fwrite($handle, $string);
}
}
Call the above in the same manner, except the third argument will now create a new line automatically. 以相同的方式调用上述代码,除了第三个参数现在将自动创建新行。
Edit following the comments: 编辑以下评论:
The a+
means that the file is open and stored in $file
and is available for reading and writing. a+
表示文件已打开并存储在$file
,并且可以读取和写入。 The a stands for append; a代表追加; meaning the fwrite
will append the file. 表示fwrite
将附加文件。
See more on the PHP documentation . 有关更多信息,请参见PHP文档 。
$file = fopen("myfile.txt", "a+");
fwrite2($file, "{$_GET['message']} | from {$_GET['sender']}");
Since you are using the URL to send data (ill-advised, but that is another point completely), you can access its contents through the superglobal variable - $_GET
. 由于您正在使用URL发送数据(建议不正确,但这完全是另一回事),因此可以通过超全局变量$_GET
访问其内容。
Notice that I have wrapped the values in curly braces. 请注意,我已将这些值括在花括号中。 This is because $_GET
is an array and if you want to interpolate arrays they must be wrapped, the same goes for class properties. 这是因为$_GET
是一个数组,如果要插值数组必须将它们包装,则类属性也是如此。
