Question

我正在过滤电话号码的文字。我的正则表达没问题。过滤器的行为应如下所示：

文字：this is demo number 205five456734

已过滤的文字：this is demo number **********。 five应被视为5，应予以阻止。

如果匹配的数字长度> 14，则不应过滤。

在这里，我试过它的工作不会显示带过滤的结果。它没有显示任何错误信息，只显示空白屏幕。

        process('this is testing number 2034342345 and this should not be filtered 20334334343443343434',$words); // Ignore $words, there are not being. They are just set of words which we are not using in function

    function process($text, $words)
       {

//      $arrwords = array(0=>'zero',1=>'one',2=>'two',3=>'three',4=>'four',5=>'five',6=>'six',7=>'seven',8=>'eight',9=>'nine');
        //Here I want to replace any word digit to zeros of same length
        $arrwords = array(0000=>'zero',000=>'one',000=>'two',00000=>'three',0000=>'four',0000=>'five',000=>'six',00000=>'seven',00000=>'eight',0000=>'nine');
        //Here I want to replace 
        preg_match_all('/[A-za-z]+/', $text, $matches);
        $arr=$matches[0];
        foreach($arr as $v)
        {
            $v = strtolower($v);
            if(in_array($v,$arrwords))
            {
                $text= str_replace($v,array_search($v,$arrwords),$text);
            }
        }
        //return $text;
        $resultSet = array();
        $l = strlen($text);
        /*if($l>14)
            echo $text;
        */
        foreach ($words as $word){
            $pattern = '/^(?:\((\+?\d+)?\)|(\+\d{0,3}))? ?\d{2,3}([-\.]?\d{2,3} ?){3,4}/';
            preg_match_all($pattern, $text, $matches, PREG_OFFSET_CAPTURE );
            //In above array replace by 0s and here check match size. if > 14 then return text
            //I want to check if matching number length is greater then 14 or not, if yes then dont filter it and return original text
            /*if(strlen($matches)>14)
            {
                return $text;
            }*/
            $this->pushToResultSet($matches);
        }
    return $resultSet;
    }

我已经重构了你的代码 - 因为我根本无法理解它，但是这是一种你可以使用的方法，效果非常好：

首先我们创建一个隐藏数字字符串的函数：

function hideNumber($numericValue){
    $returnStatement = "";
    for($i = 0; $i < strlen((string)$numericValue); $i++){
        $returnStatement .= "*";
    }
    return $returnStatement;
}

然后是过程函数：

function process($text){
    //replace any word digit to zeros of same length
    $arrwords = array('zero', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine');
    $arrvalues = array('0000', '000', '000', '00000', '0000', '0000', '000', '00000', '00000', '0000');

    //replacing the ocurrences of numbers one by one
    $cleanNumericText = str_replace($arrwords, $arrvalues, $text);

    //matching the numbers
    $re = '/(?<=[^\d]|^)[\d]{1,14}(?=[^\d]|$)/m'; 
    preg_match_all($re, $cleanNumericText, $occurrences);

    //preparing the replacement value for each correct number
    $arrHideNumbersValue = array();
    foreach($occurrences[0] as $value){
        $arrHideNumbersValue[] = hideNumber($value);
    }

    //replacing the numbers by its correspondent values
    $cleanPasswordText = str_replace($occurrences[0], $arrHideNumbersValue, $cleanNumericText);

    return $cleanPasswordText;
}

请注意，我没有使用很多foreach （str_replace可以为您替换数组出现次数）

您正在寻找的正则表达式是this one：(?<=[^\d]|^)[\d]{1,14}(?=[^\d]|$)，它将匹配1到14个字符的数字。

然后打印出来：

echo "<pre>" . process('this is testing number 203five4342345 and this should not be filtered 20334334343443343434');

正则表达式匹配和验证
