将php输出保存在文件中

2021-12-28 00:00:00 file arrays printing php

我有:

echo"
";echo"

";print_r($array2);echo"</pre>";echo"<br>";echo"<br><pre>";print_r($array3);echo"</pre>";echo"<br>";echo"<br><pre>";print_r($array4);echo"</pre>";

我需要将所有这些 print_r 打印的内容保存到一个文件中(不要在页面中打印任何内容).

我知道我需要做这样的事情:

$f = fopen("file.txt", "w");fwrite($f, "要写的文本");fclose($f);

但是我不知道怎么把里面的内容放在里面.

感谢一百万

解决方案

使用 print_r 中的 true 参数试试这个:

$f = fopen("file.txt", "w");fwrite($f, print_r($array2, true));fwrite($f, print_r($array3, true));fwrite($f, print_r($array4, true));fclose($f);

I have:

echo"<br>";echo"<br><pre>";print_r($array2);echo"</pre>";
echo"<br>";echo"<br><pre>";print_r($array3);echo"</pre>";
 echo"<br>";echo"<br><pre>";print_r($array4);echo"</pre>";

I need to save what all of these print_r print into a file (without pronting anything in the page).

I know I need to do something like that:

$f = fopen("file.txt", "w");
fwrite($f, "TEXT TO WRITE");
fclose($f); 

But I don't know how to put the contents before in it.

Thansk a million

解决方案

Try this out using the true param in the print_r:

$f = fopen("file.txt", "w");
fwrite($f, print_r($array2, true));
fwrite($f, print_r($array3, true));
fwrite($f, print_r($array4, true));
fclose($f);
