提取短代码中的字符串

Question

我有一个字符串，可能包含this is a string [e]with[/e] multiple [e]shortcodes[/e]等短代码。我想提取字符串：“with”和“shortcodes”到数组中。

$string_with_shortcodes = "this is a string [e]with[/e] multiple [e]shortcodes[/e]";

我该怎么做？

Answer 1

$count = preg_match_all("\01\[e\](.*?)\[/e\]\01", $string_with_shortcodes, $matches);
$shortcodes_array = $matches[1];

根据您提供的示例，

• $matches[0]将包含：Array("[e]with[/e]","[e]shortcodes[/e]")
• $matches[1]将包含：Array("with","shortcodes")
