我设法通过以下方式完成了我想做的事情(不使用Regex)：

解析字符串的每个字符

删除所有标签(将它们复制到临时数组并在字符串上保留占位符)

str_replace 新字符串以替换所有关键字

通过原始标签重新填充占位符

如果有人需要，这是我使用的代码：

$str = <<

Moses supposes his toeses are roses,

but Moses supposes erroneously;

for nobody's toeses are posies of roses,

as Moses supposes his toeses to be.

Ganda Moses!

STRA;

$arr1 = str_split($str);

$arr_links = array();

$phrase_holder = '';

$current_a = 0;

$goto_arr_links = false;

$close_a = false;

foreach($arr1 as $k => $v)

{

if ($close_a == true)

{

if ($v == '>') {

$close_a = false;

}

continue;

}

if ($goto_arr_links == true)

{

$arr_links[$current_a] .= $v;

}

if ($v == '

// keep collecting every char until

$arr_links[$current_a] .= $v;

$goto_arr_links = true;

} elseif ($v == '' ) { /* */

$arr_links[$current_a] .= "/a>";

$goto_arr_links = false;

$close_a = true;

$phrase_holder .= "{%$current_a%}"; /* put a parameter holder on the phrase */

$current_a++;

}

elseif ($goto_arr_links == false) {

$phrase_holder .= $v;

}

}

echo "Links Array:\n";

print_r($arr_links);

echo "\n\n\nPhrase Holder:\n";

echo $phrase_holder;

echo "\n\n\n(pre) Final Phrase (with my keyword replaced):\n";

$final_phrase = str_replace("Moses", "Moses", $phrase_holder);

echo $final_phrase;

echo "\n\n\nFinal Phrase:\n";

foreach($arr_links as $k => $v)

{

$final_phrase = str_replace("{%$k%}", $v, $final_phrase);

}

echo $final_phrase;

输出：

链接数组：

Array

(

[0] => Moses

[1] => Moses

)

词组：

Moses supposes his toeses are roses,

but {%0%} supposes erroneously;

for nobody's toeses are posies of roses,

as Moses supposes his toeses to be.

Ganda {%1%}!

(上)最终词组(替换为我的关键字)：

Moses supposes his toeses are roses,

but {%0%} supposes erroneously;

for nobody's toeses are posies of roses,

as Moses supposes his toeses to be.

Ganda {%1%}!

最终词组：

Moses supposes his toeses are roses,

but Moses supposes erroneously;

for nobody's toeses are posies of roses,

as Moses supposes his toeses to be.

Ganda Moses!
