php add days to date in PHP
<p>I want to add or remove a day (or more) depending on a dynamic value. Some times i want to remove / add 4 days, and next time maybe 9. How would i be able to do this in PHP? I was hoping there was i timestamp solution so i could use number of secounds.</p>

<p>Example: 2012-04-21 + 86400 // Add one day</p>

<p>Is there any good solution for this? or is there other good methods where i can use dynamic values to remove or add any number of days i wanted.</p>

<p>Please feel free to suggest!</p>
