如何更改列表的分隔符？

Question

$variable = 'one, two, three'; 

如何用<br>替換單詞之間的逗號？

$variable應該變成：

one<br> 
two<br> 
three 

Answer 1

要麼使用str_replace：

$variable = str_replace(", ", "<br>", $variable); 

，或者，如果你想要做其他事情與元素之間，explode()和implode()：

$variable_exploded = explode(", ", $variable); 
$variable_imploded = implode("<br>", $variable_exploded); 

Answer 2

$variable = str_replace(", ","<br>\n",$variable); 

應該這樣做。

Answer 3

$variable = explode(', ',$variable); 
$variable = implode("<br/>\n",$variable); 

然後，您可以只echo $variable

Answer 4

你可以這樣做：

$variable = str_replace(', ',"<br>\n",$variable); 

Answer 5

$variable = preg_replace('/\s*,\s*/', "<br>\n", $variable); 

這需要你進入正則表達式的土地，但這樣會處理逗號之間的隨機間距，例如病例

$variable = 'one,two, three'; 

或

$variable = 'one , two, three';
