    字符串逗号分隔成字符串数组

    Given an array and we have to create a comma delimited string from the array without using library function.

    给定一个数组,我们必须使用该数组创建一个逗号分隔的字符串,而无需使用库函数。

    Example:

    例:

        Input: 
        array("Google","Bing","Yahoo!","DuckDuckGo")
    
        Output:
        comma delimited string: "Google, Bing, Yahoo!, DuckDuckGo"
    
    

    PHP代码无需使用库函数即可从数组创建逗号分隔的字符串 (PHP code to create comma delimited string from an array without using library function)

    <?php
    //PHP code to reverse the string without 
    //using library function
    
    //function definition 
    //it accepts an array and returns comma delimited string
    function create_string($arr){
        //variable to store the string
        $str = '';
        
        for($i = 0; $i < count($arr); $i++){
            $str .= $arr[$i];
            if($i < (count($arr) -1)){
              $str .= ", ";
            }
        }
        
        //return the result i.e. comma delimited string
        return $str;
        
    }
    
    //main code i.e. function calling
    $arr = array("New Delhi","Mumbai","Chennai","Banglore");
    $result = create_string($arr);
    echo "array is: ". "<br/>";
    print_r($arr);
    echo "comma delimited string: " .$result ."<br/>";
    
    $arr = array("Google","Bing","Yahoo!","DuckDuckGo");
    $result = create_string($arr);
    echo "array is: ". "<br/>";
    print_r($arr);
    echo "comma delimited string: " .$result ."<br/>";
    ?>
    
    

    Output

    输出量

    array is: 
    Array
    (
        [0] => New Delhi
        [1] => Mumbai
        [2] => Chennai
        [3] => Banglore
    )
    comma delimited string: New Delhi, Mumbai, Chennai, Banglore
    array is: 
    Array
    (
        [0] => Google
        [1] => Bing
        [2] => Yahoo!
        [3] => DuckDuckGo
    )
    comma delimited string: Google, Bing, Yahoo!, DuckDuckGo
    
    

    Explanation:

    说明:

    We use for loop to read the array and store it into a string delimited by a (,) whenever one value in the array is printed. This continues until we reach the last string to avoid printing another comma at the end of the list.

    每当打印数组中的一个值时,我们使用for循环读取数组并将其存储到以( , )分隔的字符串中。 这一直持续到我们到达最后一个字符串为止,以避免在列表末尾打印另一个逗号。
