birthday greeting logic in PHP

A script for birthday greeting logic in PHP that first validates a given date of birth and wishes someone a happy birthday if their birthdate matches the current date. This can be a fun and engaging feature for a website. The code you’ve shared seems to work well for its intended purpose.

Here’s a breakdown of what the code does:

1. It takes a date of birth in the format ‘YYYY-MM-DD’ and splits it into its components (year, month, and day).
2. It uses the checkdate function to validate whether the provided date is a valid date or not. If it’s not a valid date, it displays an error message. If it’s valid, it proceeds to the next step.
3. It compares the month and day of the birthdate (excluding the year) with the current month and day using the date function. If they match, it wishes the user a happy birthday; otherwise, it informs them that today is not their birthday.
4. There’s a reminder to reset the computer’s local machine time back to the current date and time after testing.

This code snippet is a good starting point for implementing a birthday greeting feature on a website. You can integrate it into your web application where user birthdates are stored, and the comparison is made when users log in or visit your site.

verifying if given date of birth is permitted in a logical restriction using php
Hey there have you tried to add age restriction in your web application

Cool!

Keep in mind that for security reasons, you should not solely rely on client-side validation like this for important actions, especially if age verification is a critical part of your service. Server-side validation and verification should also be implemented to ensure the accuracy and security of user data.

that’s nice to wave off some underage or overage from participating your services
You just need a range of age.

You only want user’s date of birth with in the range specified.

Need for Birthday Confirmation

Sometimes you may want to throw birthday message to user when they visit your web application
you may consider writting a logic in php by stating if the current date is same as the user date of birth

Alright you might be seeing some different or something similar or simpler your suggested logic

So far we have validated date and used formless date inputs (bootstrap no form control)

you may try it out

well nevertheless let’s start

the user date of birth used for this project is 1975-02-23

let us validate the date of birth first

 <?php 
$thedob = '1975-02-23'; //this is the date being checked
$thedob = explode('-', $thedob);
$year_dob = $thedob[0];
$month_dob = $thedob[1];
$day_dob = $thedob[2];

//since it a bool we are using logic to output it result
if(!checkdate($month_dob, $day_dob, $year_dob)){
	echo 'The date of birth is Invalid : Hey! pls. Retreat';
}else{
	echo 'The date of birth is Valid : Continue my friend';
}

?>

Using the birthday validation

let’s wish the user happy birthday if the user date of birth matches the current day and month match

hope you know birthday is compared using month and day excluding year

since the date of birth is 1975-02-23 we will compare 02-23(february 23rd) with the current month and day

 <?php 
$thedob = '1975-02-23'; //this is the date being checked
$thedob = explode('-', $thedob);
$year_dob = $thedob[0];
$month_dob = $thedob[1];
$day_dob = $thedob[2];

//since it a bool we are using logic to output it result
if(!checkdate($month_dob, $day_dob, $year_dob)){
	echo 'The date of birth is Invalid : Hey! pls. Retreat';
}else{
	//THE BIRTHDAY WISH
	if(date('m-d') == ($month_dob.'-'.$day_dob)){
		echo 'Hey Happy Birthday: it is a valid date of birthday';
	}else{
		echo 'Today is not your birthday. The date of birth is Valid : Continue my friend';
	}
}

?>

Now it is time to run our test if you are on localhost just reset your local machine date and time to match date of birth month and used in this project

Oh! less i forgot remeber to reset back your computer local machine time back to your up to date current time

Check your watch or mobile phone for current time and date if you’ve forgotten.
