PHP reads the value in CDATA in XML data

// During the development process, when loading CDATA when retrieving XML, the internal value cannot be read
$content = simplexml_load_string('< /content>');
echo (string) $content;
$foo = simplexml_load_string('');
echo (string) $foo->content;
// Automatically filter CDATA internal parameters through the following method
$content = simplexml_load_string('', null, LIBXML_NOCDATA);
Hope it helps everyone

The above introduces PHP to read the CDATA value in XML data, including the content. I hope it will be helpful to friends who are interested in PHP tutorials.
