爱站程序员基地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\"
[/code]
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 stringfunction 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/>\";?>
[/code]
Output
输出量
array is:Array([0] => New Delhi[1] => Mumbai[2] => Chennai[3] => Banglore)comma delimited string: New Delhi, Mumbai, Chennai, Banglorearray is:Array([0] => Google[1] => Bing[2] => Yahoo![3] => DuckDuckGo)comma delimited string: Google, Bing, Yahoo!, DuckDuckGo
[/code]
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。
