_wptexturize_pushpop_element ( $text, $stack, $disabled_elements )
_wptexturize_pushpop_element: 当WordPress处理文本时,这个函数用于将元素”推”和”弹”到堆栈中。它被用来跟踪某些类型的标签(例如,开头和结尾的引号),以便它们可以被正确地替换成它们的印刷品。
搜索禁用的元素标签。在标签打开时将元素推入堆栈,在标签关闭时将元素弹出。
假设`$text’的第一个字符是标签打开,最后一个字符是标签关闭。假设`$text`的第二个字符是可选的`/`,表示关闭,如“。
function _wptexturize_pushpop_element( $text, &$stack, $disabled_elements ) { // Is it an opening tag or closing tag? if ( isset( $text[1] ) && '/' !== $text[1] ) { $opening_tag = true; $name_offset = 1; } elseif ( 0 === count( $stack ) ) { // Stack is empty. Just stop. return; } else { $opening_tag = false; $name_offset = 2; } // Parse out the tag name. $space = strpos( $text, ' ' ); if ( false === $space ) { $space = -1; } else { $space -= $name_offset; } $tag = substr( $text, $name_offset, $space ); // Handle disabled tags. if ( in_array( $tag, $disabled_elements, true ) ) { if ( $opening_tag ) { /* * This disables texturize until we find a closing tag of our type * (e.g. <pre>) even if there was invalid nesting before that. * * Example: in the case <pre>sadsadasd</code>"baba"</pre> * "baba" won't be texturized. */ array_push( $stack, $tag ); } elseif ( end( $stack ) == $tag ) { array_pop( $stack ); } } }
