Warning: Date() Expects Parameter 2 to Be Long, String Given In

Warning: date() expects parameter 2 to be long, string given in

date() expects a unix timestamp... I imagine you are passing it a date as a string.

e.g. 2010-10-10

You should use:

$this->expiry_date = date("m/d/Y", strtotime($rows['expiry_date']));

Or better yet, use the DateTime object.

$expiry_date = new DateTime($rows['expiry_date']);
$this->expiry_date = $expiry_date->format('m/d/Y');

Your click_time field probably is of type DATETIME, and date() expects the second parameter to be a timestamp (long).

Try replacing line #2 with:

$click_time_to_date = new DateTime($mysql['click_time']);

Or make sure that your click_time field is of type TIMESTAMP.

The variable you supplied ($songs->PLAYEDAT) is probably a string or at best a DateTime object.

If it's a DateTime object:

$songs->PLAYEDAT->format('Y-m-d H:i:s')

If it's a string representation of a date:

date('Y-m-d H:i:s', strtotime($songs->PLAYEDAT))

UPDATE: Answer specific to this question copied back from comment below

date('Y-m-d H:i:s', intval($songs->PLAYEDAT[0]))

Since 'day' is a column in mysql table, try

 $this->db->where('DATE(day)', $datee);

Warning: date() expects parameter 2 to be long

Date expects parameter 2 to be a long. i.e. it expects a number to be returned.

You return a string (assuming) with get_post_meta
You need to convert it to a time first before you can return it (a date long)

Instead try

$day = date("l, F jS", strtotime(get_post_meta($post->ID, 'date_value', true)));

The strtotime function return an int as shown here

Struggling with strtotime, getting expect parameter 2 to be long error

Read the documentation of strtotime(): http://php.net/strtotime

It states that:

time [-> the first parameter]
A date/time string. Valid formats are explained in Date and Time Formats.
now [-> the second parameter]
The timestamp which is used as a base for the calculation of relative dates.

So, only the first parameter is a time expression in string form. The second parameter is the date you start from. (+ 1 year from the unix timestamp strtotime($_POST['cdr_original_install_date']) on)

So use:

strtotime('+ 1 year', strtotime($_POST['cdr_original_install_date']));
