如何从字符串中删除标签？

Question

考虑以下:

$string = "A string with {LABELS} and {more|232} {lbls} and some other stuff";
echo str_replace('/(\{.*?\})/', '', $string);

我正在尝试删除所有标签(标签之间是任何文字{brackets}).预期的产出是:

A string with and and some other stuff

但我得到的是原始字符串:

A string with {LABELS} and {more|232} {lbls} and some other stuff

我究竟做错了什么？

str_replace不能使用正则表达式,而是使用preg_replace:
