Last update on December 20 2024 10:18:41 (UTC/GMT +8 hours)

Write a PHP script to get the last 6 months from the current month.

Sample Solution:

PHP Code:

<?php
// Initialize an empty array to store the months
$months = [];

// Loop through 6 iterations to generate the last 6 months
for ($i = 1; $i <= 6; $i++) 
{
    // Generate the date string for the first day of the month $i months ago
    $date = date('Y-m-01', strtotime(date('Y-m-01') . " -$i months"));
    
    // Append the date string to the $months array
    $months[] = $date;
}

// Output the array containing the last 6 months
var_dump($months);
?>

Output:

array(6) {                                                  
  [0]=>                                                     
  string(8) "2017-01%"                                      
  [1]=>                                                     
  string(8) "2016-12%"                                      
  [2]=>                                                     
  string(8) "2016-11%"                                      
  [3]=>                                                     
  string(8) "2016-10%"                                      
  [4]=>                                                     
  string(8) "2016-09%"                                      
  [5]=>                                                     
  string(8) "2016-08%"                                      
} 

Explanation:

In the exercise above,

• for ($i = 1; $i <= 6; $i++): Initiates a for loop to iterate through the last 6 months.
• $months[] = ...: Appends each generated date string to the '$months' array.
• date('Y-m-01', strtotime(date('Y-m-01') . " -$i months")): Generates the date string for the first day of the month $i months ago.
• var_dump($months);: Outputs the array containing the last 6 months for debugging purposes.
