嚴格的標準：只有變量應該通過參考傳遞[5.6]

Question

我有錯誤從PHP腳本流。

Strict Standards: Only variables should be passed by reference in /home/x/public_html/xstream/episodestream.php on line 114

<?php 
$url = $cap['seo']; 
$numero = end(explode('-', $url)); 
$palabra1 = str_replace($numero, '', $url); 
$final  = $palabra1; 
?> // line 114 
<?php if ($numero <= 1) {} else {?> // line 115 

Answer 1

閱讀PHP doc of end：

The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.

這意味着你不能直接傳遞explode功能end。相反，您需要分兩步進行：

$var = explode('-', $url); 
$numero = end($var);
