php生成文件

a.php<?php$a="****";require_once dirname(__FILE__) . '/b.php';?>b.php<?php............echo $a;.......?>之后生成  xxx.txt  内容是 b.php里的内容这个功能要怎么实现?本来使用下面方法做的,但是写入的内容有 双引号和单引号[code=php]$myfile = fopen("protected/views/1/_form.php", "w") or die("Unable to open file!");$txt = "Bill Gates\n";fwrite($myfile, $txt);

$s =<<< 'TXT'<?php............echo $a;.......?>TXT;file_put_contents('c.php', $s);

$data = file_get_contents('b.php');file_put_contents('c.php', $data, true);

Salin selepas log masuk

<?php............echo $a;    //变量a没有转义     这个用替换处理吗?.......?>

$data = file_get_contents('http://localhost/a.php');file_put_contents('xxx.txt', $data);

<?php$a=1;$s =<<< 'TXT'<?php....... $a;......?>TXT;

<?php....... 1;......?>
