我想忽略包含在PHP

Question

空間例如HTML標記堅強，如果我有以下格式的數組

<div><strong>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;</strong></div> 

<div><strong>Ravjaja</strong></div> 

<div><strong>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</strong></div> 

<div><strong>yuaiiaiia</strong></div> 

<div></div> 

我想從空間忽略，這意味着我的數組應該成爲像這樣除去

<div>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;</div> 

<div><strong>Ravjaja</strong></div> 

<div>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</div> 

<div><strong>yuaiiaiia</strong></div> 

<div></div> 

<div></div> 

後是否有任何可能的方式我認爲拆分並使用在PHP 陣列函數代替我以這種方式試圖

$ keywords = preg_split（「<div>」，$ lval）; print_r（$ keywords）; 和思想來提取每個標籤並刪除強勁，但我無法以這種方式做

Answer 1

$elements = array(
    '<div><strong>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;</strong></div>', 
    '<div><strong>Ravjaja</strong></div>', 
    '<div><strong>&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</strong></div>', 
    '<div><strong>yuaiiaiia</strong></div>', 
    '<div></div>' 
); 

foreach ($elements as $key => $element) { 
    if (strpos('&nbsp', $element) !== FALSE) { 
     $elements[$key] = str_replace('<strong>', '', $element); 
     $elements[$key] = str_replace('</strong>', '', $element); 
    } 
} 

Answer 2

唯一可行的方法應該是這樣的

$my_array=str_replace("<div><strong>&nbsp;","<div>",$my_array); 
    $my_array=str_replace("&nbsp;</strong>","",$my_array);
