php - 提取大括号正则表达式php之间的所有值

Question

我有这种形式的内容

$content ="<p>This is a sample text where {123456} and {7894560} ['These are samples']{145789}</p>";

我需要数组中大括号之间的所有值，如下所示:

array("0"=>"123456","1"=>"7894560","2"=>"145789")

我试过这段代码:

<?php
preg_match_all("/\{.*}\/s", $content, $matches);
?>

但我在这里获取从内容中第一个大括号到最后一个大括号的值。如何获得上述格式的数组？我知道我使用的模式是错误的。应该给出什么来获得上面显示的期望输出？

Answer 1

像这样...

<?php
$content ="<p>This is a sample text where {123456} and {7894560} ['These are samples']{145789}</p>";
preg_match_all('/{(.*?)}/', $content, $matches);
print_r(array_map('intval',$matches[1]));

输出:

Array
(
    [0] => 123456
    [1] => 7894560
    [2] => 145789
)
