i have this error after upgrade to php 7.1 and update wordpress core:
PHP Warning: A non-numeric value encountered in /wp-includes/SimplePie/Parse/Date.php on line 694
here the code of that file
public function date_w3cdtf($date)
{
static $pcre;
if (!$pcre)
{
$year = '([0-9]{4})';
$month = $day = $hour = $minute = $second = '([0-9]{2})';
$decimal = '([0-9]*)';
$zone = '(?:(Z)|([+\-])([0-9]{1,2}):?([0-9]{1,2}))';
$pcre = '/^' . $year . '(?:-?' . $month . '(?:-?' . $day . '(?:[Tt\x09\x20]+' . $hour . '(?::?' . $minute . '(?::?' . $second . '(?:.' . $decimal . ')?)?)?' . $zone . ')?)?)?$/';
}
if (preg_match($pcre, $date, $match))
{

// Fill in empty matches
for ($i = count($match); $i <= 3; $i++)
{
$match[$i] = '1';
}
for ($i = count($match); $i <= 7; $i++)
{
$match[$i] = '0';
}
// Numeric timezone
if (isset($match[9]) && $match[9] !== '')
{
$timezone = $match[10] * 3600;
$timezone += $match[11] * 60;
if ($match[9] === '-')
{
$timezone = 0 - $timezone;
}
}
else
{
$timezone = 0;
}
// ((LINE 694)) Convert the number of seconds to an integer, taking decimals into account
$second = round($match[6] + $match[7] / pow(10, strlen($match[7])));
return gmmktime($match[4], $match[5], $second, $match[2], $match[3], $match[1]) - $timezone;
}
else
{
return false;
}
}
the error is come from this line :
$second = round($match[6] + $match[7] / pow(10, strlen($match[7])));
Any ideas how to tackle this or what it is ? maybe i need to add if (is_numeric
i change that line to below and the errors gone.
$second = round((int)$match[6] + (int)$match[7] / pow(10, strlen($match[7])));
