PHP：如何删除“[”和“]”之间的字符串

Question

我需要删除[...]内的字符串，包括“[]”本身。我尝试从这个网站搜索解决方案。我有一个线索，我应该尝试使用preg_replace，但它对我来说似乎太专业了。

例如：

[gallery ids="92,93,94,95,96,97,98,99,100" orderby="rand"] Description The thirty-two storey resort condominium in Phuket, located Just 150m from Patong beach where choices of activities, water sp 

我需要从示例文本中删除 [gallery ids =“92,93,94,95,96,97,98,99,100”orderby =“rand”] 。它始终以 [gallery ids =“。

开头

请建议。

Answer 1

试试这个：

$string = '[gallery ids="92,93,94,95,96,97,98,99,100" orderby="rand"] Description The thirty-two storey resort condominium in Phuket, located Just 150m from Patong beach where choices of activities, water sp ';
$string = preg_replace('/\[gallery ids=[^\]]+\]/', '', $string);

故障：

\[gallery ids=查找以[gallery ids=

开头的子字符串

[^\]]+\]匹配一个或多个不是]的字符，直到您到达]

然后将''取代整个匹配的部分，并且你有新的字符串。
