Errors seen during installation about PHP

[محروم.كوم]

Hello,

Any idea why this is happening?

Top of install page:
Code:
Deprecated: Assigning the return value of new by reference is deprecated in /usr/local/apache2/htdocs/vbulletin/includes/class_core.php on line 2529 Deprecated: Function set_magic_quotes_runtime() is deprecated in /usr/local/apache2/htdocs/vbulletin/includes/class_core.php on line 1644 Deprecated: Assigning the return value of new by reference is deprecated in /usr/local/apache2/htdocs/vbulletin/includes/functions.php on line 933 Deprecated: Assigning the return value of new by reference is deprecated in /usr/local/apache2/htdocs/vbulletin/includes/functions.php on line 937

Bottom of install page:
Code:
Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for 'PDT/-7.0/DST' instead in /usr/local/apache2/htdocs/vbulletin/includes/adminfunctions.php on line 390 __DEFINE_LIKE_SHARE__
