1.定义正则
$ex = "/\d+/";
2.检测并存入数组
$arr = [];
txt = '';
preg_match_all($ex,$txt,$arr);
例:
txt = 'TC-比特币>BTC-比特币 </a><td class=market-cap data-usd=116666294488 data-cny=807815528757 data-btc=17324675>¥8,078亿<td><a href=/currencies/bitcoin/#markets target=_blank class=price data-usd=6734 data-cny=46628 data-btc=1>¥46,628</a><td>1,732万<td><a href=';
提取出的数字:
array (
0 =>
array (
0 => '116666294488',
1 => '807815528757',
2 => '17324675',
3 => '8',
4 => '078',
5 => '6734',
6 => '46628',
7 => '1',
8 => '46',
9 => '628',
10 => '1',
11 => '732',
),
