如何更改列表的分隔符？

Question

$variable = 'one, two, three'; 

如何用<br>替换单词之间的逗号？

$variable应该变成：

one<br> 
two<br> 
three 

Answer 1

要么使用str_replace：

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

，或者，如果你想要做其他事情与元素之间，explode()和implode()：

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

Answer 2

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

应该这样做。

Answer 3

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

然后，您可以只echo $variable

Answer 4

你可以这样做：

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

Answer 5

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

这需要你进入正则表达式的土地，但这样会处理逗号之间的随机间距，例如病例

$variable = 'one,two, three'; 

或

$variable = 'one , two, three';
