PHP naming conventions? [closed]

Answer 1

Quoted from: http://tnx.nl/php.html

PHP has inconsistent function naming
There is no apparent system in underscore(s) versus no underscore(s):

underscore               no underscore:

stream_get_line          readline
disk_free_space          diskfreespace
is_object                isset
mcal_day_of_week         jddayofweek
set_error_handler        setlocale
snmp_get_quick_print     snmpget
get_browser              getallheaders
base64_encode            urlencode
image_type_to_mime_type  imagetypes
msql_num_fields          mysql_numfields
php_uname                phpversion
strip_tags               stripslashes
bind_textdomain_codeset  bindtextdomain
cal_to_jd                gregoriantojd
str_rot13                strpos

Answer 2

Welcome to php. This has been a topic so many times. Bottom line is, the only way to get over it is using a php centric ide/editor that suggests. By the way that is just half the problem you will also see functions where the order is oposite. Like

(mixed $needle , array $haystack)

and then

(array $haystack , string $needle)

So get used to it, or get out is the motto.
