php sprintf date code example
Example 1: php convert string to date
$time = strtotime('10/16/2003');
$newformat = date('Y-m-d',$time);
echo $newformat;
Example 2: php timestamp to date
<?php
echo date('m/d/Y H:i:s', 1541843467);
?>
Example 3: php sprintf
There are already some comments on using sprintf to force leading leading zeros but the examples only include integers. I needed leading zeros on floating point numbers and was surprised that it didn't work as expected.
Example:
<?php
sprintf('%02d', 1);
?>
This will result in 01. However, trying the same for a float with precision doesn't work:
<?php
sprintf('%02.2f', 1);
?>
Yields 1.00.
This threw me a little off. To get the desired result, one needs to add the precision (2) and the length of the decimal seperator "." (1). So the correct pattern would be
<?php
sprintf('%05.2f', 1);
?>
Output: 01.00

Example 4: php sprintf
<?php
$num = 5;
$location = 'tree';
$format = 'There are %d monkeys in the %s';
echo sprintf($format, $num, $location);
