我想把这个带进这根绳子
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/preg_replace_callback" rel="nofollow"\\\\code>preg_replace_callback () :
$str = preg_replace_callback( /d+/ , function($match) {
return replaceNumToWord($match[0]);
}, $str);
如果您需要使用不支持匿名功能的旧 PHP 版本 :
function _num2word_cb($match) {
return replaceNumToWord($match[0]);
}
$str = preg_replace_callback( /d+/ , _num2word_cb , $str);
外注 : < code> d/code> 模式将匹配任何数字序列, 不论它们出现在何处, 例如, 它将匹配“ my10, 20, 30foo” 中的 10, 20 和 30 。 如果您想要匹配仅20 个数字, 您可以将该模式更改为 < coded/code > 。
您可以使用"http://php.net/manual/en/formation.preg-replace-callback.php" rel=“nofollow”>preg_referf_callback 。
function transNumber($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 。
