date calculation

[phpmady]

Hi guys,

 

$T_Start_Date = "2011-10-23";

$P_Days = "30";

 

I tried this Its working:

$T_End_Date = date('Y-m-d', strtotime("+$P_Days days");

 

but why am not getting this:

$T_End_Date = date($T_Start_Date, strtotime("+$P_Days days"));

 

 

thanks

Because date() expects a format for the first argument.

 

Try:

<?php
$T_End_Date = date('Y-m-d', strtotime("+ $P_Days days",$T_Start_Date));

But i am geting the result like this

 

1970-03-02

And strtotime() expects a timestamp for the second argument

Pick:

"$T_Start_Date + $P_Days days"

strtotime("+ $P_Days days", strtotime($T_Start_Date))

Although requinix's solution should work, this is simpler:

$T_Start_Date = "2011-10-23";
$P_Days = "30";

$T_End_Date = date('Y-m-d', strtotime("$T_Start_Date +$P_Days days"));
echo $T_End_Date;

 

Output: 2011-11-22

Pick:

"$T_Start_Date + $P_Days days"

strtotime("+ $P_Days days", strtotime($T_Start_Date))

 

GAHHHH!!!! Gonna have to quit posting without sleep.

@mjdamato - not to mention twice as fast, which is a big deal when working with PHP's date functions.
