字符串内任意数字上使用函数
原标题:Use function on any numbers within a string

我想把这个带进这根绳子

进入 Fifty 五 Banana Slush 25 测试


Now I have the function to convert any numbers to words which is replaceNumtoWord($number)

然而,我需要使用“强”字符串,找到每个数字,然后在字符串中对每个数字使用函数,然后从中提取数字。

有什么想法或建议吗?

您可以使用"http://php.net/manual/en/formation.preg-replace-callback.php" rel=“nofollow”>preg_referf_callback

function transNumber($str) {
  return preg_replace_callback( /d+/ , function($matches){
            return replaceNumtoWord($matches[0]);
         }, $str);
}

如果您的php 版本 & lt; 5. 3, 那么您需要定义传递到 preg_ replace_ 回调的函数 。
