How to add 300 to a variable on each iteration using a for loop in php?

本文关键字：迭代变量添加 for php 循环 | 更新日期: 2023-09-27

我试图做一个循环，迭代6次，每次迭代我想添加300到变量$count。

 $count = 300;
 for ($i=0; $i < 6 ; $i++) { 
     $count + 300;
     echo $count; //300300300300300300
 }

我想达到的结果是

echo $count // 300600900120018002400

我怎样才能达到这些结果?

试试这个，给$count赋值。$count = $count + 300;

<?php
 $sum_number = 300;
 $count = 0;
 for ($i=0; $i < 6 ; $i++) { 
     $count = $count + $sum_number;
     echo $count."'n"; 
 }
?>

try this

    $count = 0;
    for ($i = 0; $i < 6; $i++) {
        $count = $count + 300;
        echo $count; 
    }

试试这个

for ($i=0; $i <= 7 ; $i++) { 
      if($i){
       $count .= ($i+1) * 300;
       }else{
       $count = 300;
       } 
   }
  echo $count; // 30060090012001500180021002400

TRY this

<?php
 $count = 0;
 for ($i=0; $i < 6 ; $i++) { 
     $count= $count+ 300;
     echo $count; //300600900120015001800
 }
?>

嗯，你必须再次循环计数，试试这个:

 for ($i=0; $i < 6 ; $i++) { 
     if($i == 0) {
        $count = 300;
     } else {
        $count = $count + 300;
     }
     echo $count;
 }
