Looks like it can be done with preg_replace()but havent found a solution that works for me.

You don't need regex for a static string.
静态字符串不需要正则表达式。
Replace those parts of the texts with nothing:
用空替换文本的那些部分：
$string = str_replace("//<![CDATA[","",$string);
$string = str_replace("//]]>","",$string);

If you must...
如果你必须...
$s = preg_replace('~//<!\[CDATA\[\s*|\s*//\]\]>~', '', $s);
This will remove the whole line containing each tag without messing up the indentation of the enclosed code.
这将删除包含每个标签的整行，而不会弄乱所附代码的缩进。

你也可以试试，
$s=str_replace(array("//<![CDATA[","//]]>"),"",$s);

I use like this to remove <![CDATA[]]but on single line now work for me, dont know if for multiple line string.
我用这样的方式删除，<![CDATA[]]但现在单行对我有用，不知道是否适用于多行字符串。
preg_match_all('/CDATA\[(.*?)\]/', $your_string_before_this, $datas);
$string_result_after_this = $datas[1][0];

$nodeText = '<![CDATA[some text]]>';
$text = removeCdataFormat($nodeText);
public function removeCdataFormat($nodeText)
{
$regex_replace = array('','');
$regex_patterns = array(
'/<!\[CDATA\[/',
'/\]\]>/'
);
return trim(preg_replace($regex_patterns, $regex_replace, $nodeText));
}

If <![CDATA[contains some html special character, e.g. &, ", ', <, >and you will work with the rest of the string as it is still XML, you should escape those chars.
Otherwise you will make your XML invalid.
如果<![CDATA[包含一些 html 特殊字符，例如&, ", ', <,>并且您将使用字符串的其余部分，因为它仍然是 XML，您应该转义这些字符。否则，您将使您的 XML 无效。
function removeCDataFromString(string $string)
{
return preg_replace_callback(
'~<!\[CDATA\[(.*)\]\]>~',
function (array $matches) {
return htmlspecialchars($matches[1], ENT_QUOTES | ENT_SUBSTITUTE, 'UTF-8');
},
$string
);
}

use str_replace()instead of preg_replace()it's lot easier
使用str_replace()而不是preg_replace()更容易
$var = str_replace('<![CDATA[', '', $var);
$var = str_replace(']]','',$var);
echo $var;
