php替换大括号内的文字

Posted 2023-03-11

字符串 $data['orderno']="fewewfewfewfwefewfwefef[dewfew]dweqfewfewfewfewf[3432534]";
$reg = '/\[(\w+)\]/';
$data['orderno'] = preg_replace($reg,'[1111111]',$data['orderno']);
输出：$data['orderno']="fewewfewfewfwefewfwefef[1111111]dweqfewfewfewfewf[1111111]";

我怎么没法替换数组里头的值呢？就是把dewfew 改成1111111。
不好意思，要替换的内容还有文字的情况。
$data['orderno']="fewewfewfewfwefewfwefef[啊啊啊啊]dweqfewfewfewfewf[哇哇哇哇]";
请问这个时候怎么替换呢？
$data['orderno']="fewewfewfewfwefewfwefef[你好]dweqfewfewfewfewf[你好]";

$data['orderno']="fewewfewfewfwefewfwefef[dewfew]dweqfewfewfewfewf[3432534]";
echo '原始字串:'.$data['orderno'].'<br>';
$reg = '/\[[\w]+]/';
$data['orderno'] = preg_replace($reg,'[1111111]',$data['orderno']);
echo '替换后:'.$data['orderno'];追问

$data['orderno']="fewewfewfewfwefewfwefef[啊啊啊啊]dweqfewfewfewfewf[哇哇哇哇]";
echo '原始字串:'.$data['orderno'].'';
$reg = '/\[[^x00-xff\w]+]/';
$data['orderno'] = preg_replace($reg,'[你好]',$data['orderno']);
echo '替换后:'.$data['orderno'];

好像不行吧。
$str = $data['orderno'];
$reg = '/\[[^x00-xff\w]+]/';
$str = preg_replace($reg,'[NG工程状况]',$str);

我不知道你是怎么说不行的，我这边是可以的，输出如下:
原始字串:fewewfewfewfwefewfwefef[啊啊啊啊]dweqfewfewfewfewf[哇哇哇哇]
替换后:fewewfewfewfwefewfwefef[NG工程状况]dweqfewfewfewfewf[NG工程状况]

代码：
$data['orderno']="fewewfewfewfwefewfwefef[啊啊啊啊]dweqfewfewfewfewf[哇哇哇哇]";
echo '原始字串:'.$data['orderno'].'';
$reg = '/\[[^x00-xff\w]+]/';
$data['orderno'] = preg_replace($reg,'[NG工程状况]',$data['orderno']);
echo '替换后:'.$data['orderno'];

难道我是日文的windows系统吗

参考技术A echo preg_replace('|\[([a-z]+)\]|isU','11111111',$str);
