Question:
I would like to know which function I use to compare two dates and return the largest one.
I have a form for HR registration in which the user will register their professional experiences and the date of entry into the job cannot be greater than the date of exit, so I need to check this condition and return false.
Someone would have a suggestion on how to solve this I found some solutions but the date format was in American standard which does not suit me. Att.
Answer:
In order to work with date first of all we have to keep in mind that the standard used is the American standard which requires us to use the Year-Month-Day format (Ex.: 2013-05-22).
In our example we are going to create a script that compares if date1 is greater than or equal to date2 and displaying the corresponding messages.
<?php
$data1 = '2013-05-21';
$data2 = '2013-05-22';
// Comparando as Datas
if(strtotime($data1) > strtotime($data2))
{
echo 'A data 1 é maior que a data 2.';
}
elseif(strtotime($data1) == strtotime($data2))
{
echo 'A data 1 é igual a data 2.';
}
else
{
echo 'A data 1 é menor a data 2.';
}
?>
Obs.: The command strtotime generates the timestamp of a date in text format so that we can work with the dates.
For the standard conversion, it can be done like this:
$dataString = '19/03/2013 11:22';
$date = DateTime::createFromFormat('d/m/Y H:i', $dataString);
echo $date->format('Y-m-d H:i:s');
And of course it must be tailored to your needs.
