使用fopen（）创建.php文件

Question

I'm trying this:

<a href="
<?php
$fl= $p['n'].".php";
$fh = fopen($fl, 'w') or die("Can't create file");
if($fh)
{
$code ="
<?php
// html and php combined code (the php is for sessions)
?>";
echo fwrite($file,$code); 
    fclose($file); 
}?>"></a>

The problem is that the codes inside $code are being evaluated and I need that $code simply save the codes like a string.

Answer 1

Use PHP's nowdoc feature (emphasis mine):

Nowdocs are to single-quoted strings what heredocs are to double-quoted strings. A nowdoc is specified similarly to a heredoc, but no parsing is done inside a nowdoc. The construct is ideal for embedding PHP code or other large blocks of text without the need for escaping .

Example

<?php

$test_var = 1;

$str = <<<'EOD'
Example of string
spanning multiple lines
using nowdoc syntax.
$test_var
EOD;

echo $str;

Outputs

Example of string
spanning multiple lines
using nowdoc syntax.
$test_var

So this ...

<a href="
<?php
$fh = fopen($p['n'].'.php', 'w') or die("Can't create file");
if($fh)
{
$code = <<<'EOD'
<?php
// html and php combined code (the php is for sessions)
?>"
EOD;
echo fwrite($file,$code); 
fclose($file); 
}?>"></a>

... should work for you.

Answer 2

Using "$foo" will evaluate, but '$foo' will not.

However, this is opens massive security risks so I would probably back up and take a look at what you're trying to do.
