Example output:

Array
(
    [warning_count] => 0
    [warnings] => Array()
    [error_count] => 1
    [errors] => Array
        (
            [0] => The separation symbol could not be found
        )
)

Checking errors helps debug date format issues more effectively.

3. Common Solutions

• Ensure the format and string fully match: Make sure the order of year, month, and day, as well as the separators, match the format.
• Handle optional or incomplete time information: If the string lacks time information, fill in default values, for example:

<span class="fun">$date</span> = <span class="function_ invoke__">date_create_from_format</span>('Y-m-d H:i:s', '2025-08-27 00:00:00');

• Use regex or string preprocessing: Format and validate the string before calling date_create_from_format.
• Catch errors and provide fallback: When false is returned, you can choose to throw an exception or use a default date.

4. Summary

To fix date format mismatch issues in date_create_from_format, the key points are:

1. Understand the meaning of format characters
2. Ensure the date string strictly matches the format
3. Use DateTime::getLastErrors() for debugging
4. Preprocess or provide fallback solutions when necessary

Mastering these techniques can effectively prevent errors caused by date format mismatches and improve the reliability of PHP date handling.
