我试图回显以下代码，然后将其保存到文件samplepage.php中，但它给出了一个错误。 有没有其他方法可以将这些内容粘贴到文件中

从你的代码片段中我可以观察到。 您只使用双引号（“”）启动打印脚本和HTML中提到的属性。 因此，您有两个选项，要么以单引号('')开始主脚本，要么对引号使用反斜杠(\)，使它们充当转义字符。
使用cat和hereDoc更容易:
cat <<'EOF' >SamplePage.php
<html>
<body>
<h1>Sample page</h1>
...
EOF
请注意<<'EOF'中的单引号。 这样，数据中的PHP变量就不像shell变量那样被处理了。
