Question

foreach($reciveValue as $value){

    echo $value.",";// Result: based on user input like:10,11,12,13,14
  }
echo $value; // Result: 14

内部循环的结果是：10,11,12,13,14

和外部循环是：14

我想使用循环外的所有值

Answer 1

使用以下代码将您的数组值以逗号分隔

implode(",", $reciveValue)

Answer 2

@Support Techcherry如果要使用外部数组的所有值循环然后你可以使用implode（）函数，下面是一个例子理解

<?php
    $reciveValue = array(10,11,12,13,14);   // suppose this is your array 
    foreach($reciveValue as $value){

        echo $value.",";// Result: based on user input like:10,11,12,13,14
      }
      echo "<br>";
    echo implode(',', $reciveValue);  // here implode() function convert the array value in the string form 
?>

尝试一下，它会帮助你

Answer 3

试试这个：

$value = '';
foreach($reciveValue as $val){
    $value .= $val.",";// Result: based on user input like:10,11,12,13,14
}
echo rtrim($value, ',');
