阻止PHP将反斜杠添加到字符串[关闭]

问题描述：

I have a function that builds a regex based on an array. The problem is that PHP keeps adding backslashes to some of the characters, and it keeps messing up the regex.

Here is my function:

private static $allowedPermissions = [
/*SV*/   
    'user_add',
    'user_edit',
    'user_delete',
    'user_view'];


    $regexrule = '/';

    foreach (self::$allowedPermissions as $allowedPermission) {
        $regexrule .= '\b'.$allowedPermission.'\b';
        if(end(self::$allowedPermissions) !== $allowedPermission) $regexrule .='|';
    }

    $regexrule .= "/";
    return 'regex:'.$regexrule;

It is adding backslashes where I don't expect them:

Is there a workaround?

我有一个基于数组构建正则表达式的函数。问题是PHP不断向某些字符添加反斜杠，并且它一直搞乱了正则表达式。 p>

这是我的功能： p>

  private static $ allowedPermissions = [
 / * SV * / 
'user_add'，
  n'user_edit'，
'user_delete'，
'user_view']; 
 
 
 $ regexrule ='/'; 
 
 foreach（self :: $ allowedPermissions as $ allowedPermission）{
 $  regexrule。='\ b'。$ allowedPermission。'\ b'; 
 if（end（self :: $ allowedPermissions）！== $ allowedPermission）$ regexrule。='|'; 
} 
 
 $  regexrule。=“/”; 
返回'正则表达式：'。$ regexrule; 
  code>  pre> 
 
 它正在添加反斜杠，我不指望它们： p  > 
 
 
 正则表达式：\ / \\ buser_add \\ C | \\ buser_edit \\ C | \\ buser_delete \\ C | \\ buser_view \\ C | \\ bpatient_add \\ C |  \\ \\ bpatient_edit C | \\ \\ bpatient_delete C | \\ \\ bpatient_view C | \\ \\ bmake_per C | \\ \\ bmake_per_withconfirmation C | \\ \\ bconfirm_per C | \\ \\ beval_per C | \  \ beval_per_withconfirmation \\ b | \\ bconfirm_per_report \\ b \ /  code>  p>

是否有解决方法？ p>

答

I found out that returning it in json format was adding the backslashes.
