如何更改列表的分隔符？

Question

$variable = 'one, two, three';

如何用
替换单词之间的逗号？

$variable 应该变成：

one<br>
two<br>
three

Answer 1

使用 str_replace：

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

或者，如果您想对中间的元素执行其他操作，explode() 和 implode()：

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

Answer 2

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

应该做到这一点。

Answer 3

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

然后你可以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);

这将带您进入正则表达式领域，但这将处理逗号之间随机间距的情况，例如

$variable = 'one,two, three';

或

$variable = 'one , two, three';
