如何阻止 fwrite 显示在脚本末尾写入的字节数？

Question

所以我有一个脚本，它写了几页，最后是一个html确认，页面顶部是写入的字节数，看起来不对。

如何停止显示此信息？

<?php
$filename = "".$page.".html";
$file = @fopen($filename,"x");
if($file)
{
echo fwrite($file,'html content');


fclose($file)

}   


?>

简单的回答，这一行反映了调用 fwrite 时写入了多少字节：

echo fwrite($file,'html content');

之所以，是fwrite returns这个信息，看文档：http://php.net/manual/de/function.fwrite.php

调用 fwrite 就足够了，没有 echo:

fwrite($file,'html content');

如果您想对此进行扩展，可以将字节数保存在变量中，以在出现错误时触发操作：

$bytes = fwrite($file, $htmlContent);

if (!$bytes && count($htmlContent)) {
  // Not written to file!
}

如何阻止 fwrite 显示在脚本末尾写入的字节数？

How do I stop fwrite from displaying amount of bytes written at end of script?

php
