这是另一个解决方案：
$cleaner_input = strip_tags($text);有关清理函数的其他变体，请参阅：

有一个值得信赖的strip_tags函数。但这并不是很漂亮。它只会起到消毒作用。您可以将其与字符串替换相结合，以获得花哨的下划线。
<?php
// to strip all tags and wrap italics with underscore
strip_tags(str_replace(array("<i>", "</i>"), array("_", "_"), $text));
// to preserve anchors...
str_replace("|a", "<a", strip_tags(str_replace("<a", "|a", $text)));

您可以使用带有-stdin和-dump选项的lynx来实现这一点：
<?php
$descriptorspec = array(
0 => array("pipe", "r"), // stdin is a pipe that the child will read from
1 => array("pipe", "w"), // stdout is a pipe that the child will write to
2 => array("file", "/tmp/htmp2txt.log", "a") // stderr is a file to write to
);
$process = proc_open('lynx -stdin -dump 2>&1', $descriptorspec, $pipes, '/tmp', NULL);
if (is_resource($process)) {
// $pipes now looks like this:
// 0 => writeable handle connected to child stdin
// 1 => readable handle connected to child stdout
// Any error output will be appended to htmp2txt.log
$stdin = $pipes[0];
fwrite($stdin, <<<'EOT'
