例如:
$str .= "Additional tax(2.34)";
$str .= "Additional tax(3)";
有人能帮我从字符串中提取数字吗。我需要一个像这样的数组格式
Array ( [0] => 2.34 [1] => 3 );
这应该做到:
<?php
$str = '';
$str .= "Additional tax(2.34)";
$str .= "Additional tax(3)";
if (preg_match_all('/((d+(?:.d+)?))/', $str, $matches) > 0) {
var_dump($matches[1]);
}
?>
