出现Strict Standards: Only variables should be passed by reference in的解决方法

出现Strict Standards: Only variables should be passed by reference in的解决方法

代码报错：

<br />
<b>Strict Standards</b>: Only variables should be passed by reference in <b>/xxxxx/xxxxApi.php</b> on line <b>41</b><br />
<br />
<br />
<b>Strict Standards</b>: Only variables should be passed by reference in <b>/xxxxx/xxxxApi.php</b> on line <b>41</b><br />
<br />
<br />
<b>Strict Standards</b>: Only variables should be passed by reference in <b>/xxxxx/xxxxApi.php</b> on line <b>41</b><br />
<br />

原因：

我的PHP版本是5.4.19，PHP5.3以上默认只能传递具体的变量，而不能通过函数返回值传递，所以这段代码中的explode就得移出来重新赋值了

解决办法：

$tag_sel = array_shift(explode(' ', $tag));
修改为：
$tagArr = explode(' ', $tag); $tag_sel = array_shift($tagArr);
