如何用指定日期格式输出当月奇数日期？PHP代码修改求助

Hey there! Let's fix your code to only output odd dates in the format you want. Here's the modified version with clear explanations of the key changes:

<?php 
$list = array(); 
$month = 3; // Months are 1-based in PHP, so using integer 3 is cleaner than 03
$year = 2018; 

for($d = 1; $d <= 31; $d++) { 
    // Fixed mktime parameters (correct order: hour, minute, second, month, day, year)
    $time = mktime(0, 0, 0, $month, $d, $year); 
    
    // Two checks here: ensure the day is in the target month, AND it's an odd number
    if (date('m', $time) == $month && $d % 2 !== 0) { 
        // Format the date to match "Saturday 10, FEB, 2018"
        $formattedDate = date('l j, M, Y', $time);
        // Convert the month abbreviation to uppercase
        $formattedDate = str_replace(date('M', $time), strtoupper(date('M', $time)), $formattedDate);
        $list[] = $formattedDate;
    } 
} 

echo "<pre>"; 
print_r($list); 
echo "</pre>"; 
?>

Key Changes Explained: #

• Odd Day Filter: Added $d % 2 !== 0 to the condition. The modulus operator (%) returns the remainder when dividing by 2—if it's not zero, the day is odd, so we include it.
• Fixed Timestamp Generation: Your original mktime call had the year in the wrong position (it should be the last parameter), which could lead to incorrect dates. I adjusted it to use the standard order: hour, minute, second, month, day, year.
• Matching Date Format: Switched to l j, M, Y to get the exact structure you requested:
  • l = Full weekday name (e.g., Saturday)
  • j = Day of the month without leading zeros (e.g., 10)
  • M = Three-letter month abbreviation (e.g., Feb)
• Uppercase Month: Used strtoupper() to convert the month abbreviation to uppercase (FEB) to match your desired output format.

Sample output snippet for March 2018 will look like this:

Array
(
    [0] => Thursday 1, MAR, 2018
    [1] => Saturday 3, MAR, 2018
    [2] => Monday 5, MAR, 2018
    ...
)
