php - 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（标签是之间的任何文本{brackets}）。预期的输出是：

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 不适用于正则表达式，请改用 preg_replace：

您将需要preg_replace改用：

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

请务必使用 preg_replace，但您还需要稍微不同的正则表达式来过滤掉空格并确保正确匹配大括号

$string = "A string with {LABELS} and {more|232} {lbls} and some other stuff";
echo preg_replace('/\s*\{[^}]*\}/', '', $string);
