Why Does My PHP Code Convert Month Numbers to December Instead of the Correct Month?

Converting Numbers to Month Names in PHP

Problem:

When using PHP code to convert a numeric month value (e.g., 8 for August) to its corresponding month name, the code is incorrectly returning "December" instead of "August."

Code:

<code class="php">$monthNum = sprintf("%02s", $result["month"]);
$monthName = date("F", strtotime($monthNum));

echo $monthName;</code>

Root Cause:

The sprintf() function is adding a leading zero to month values less than 10 (e.g., 8 becomes 08), which is then causing date() to interpret the value as December (month 12).

Recommended Solution (PHP >= 5.2):

Use DateTime objects for date/time manipulation:

<code class="php">$monthNum  = 3;
$dateObj   = DateTime::createFromFormat('!m', $monthNum);
$monthName = $dateObj->format('F'); // March</code>

Alternative Solution (Older PHP Versions):

<code class="php">$monthNum  = 3;
$monthName = date('F', mktime(0, 0, 0, $monthNum, 10)); // March</code>
