Mobile::UserAgent - mobile user agent string parsing class
### Print the information parsed from a user-agent string: use Mobile::UserAgent; my $useragent = 'Nokia6600/1.0 (4.09.1) SymbianOS/7.0s Series60/2.0 Profile/MIDP-2.0 Configuration/CLDC-1.0'; my $uaobj = new Mobile::UserAgent($useragent); if ($uaobj->success()) { print 'Vendor: ' . $uaobj->vendor() . "\n"; print 'Model: ' . $uaobj->model() . "\n"; print 'Version: ' . $uaobj->version() . "\n"; print 'Series60: ' . $uaobj->isSeries60() . "\n"; print 'Imode?: ' . $uaobj->isImode() . "\n"; print 'Mozilla?: ' . $uaobj->isMozilla() . "\n"; print 'Standard?: ' . $uaobj->isStandard() . "\n"; print 'Rubbish?: ' . $uaobj->isRubbish() . "\n"; } else { print "Not a mobile user-agent: $useragent\n"; } ### Determine if the client is a mobile device. use Mobile::UserAgent (); use CGI (); # Check 1: (check if it sends a user-agent profile URL in it's headers) foreach my $name ('X_WAP_PROFILE','PROFILE','13_PROFILE','56_PROFILE') { if (exists($ENV{"HTTP_$name"})) { print "Client has a user-agent profile header, so it's probably a mobile device.\n"; last; } } # Check 2: (check if it supports WML): my $q = new CGI(); if ($q->Accept('text/vnd.wap.wml') == 1) { print "Client supports WML so it's probably a mobile device.\n"; } # Check 3: (check if this class can parse it) my $uaobj = new Mobile::UserAgent(); if ($uaobj->success()) { print "Client's user-agent could be parsed, so it's a mobile device.\n"; }
Parses a mobile user agent string into it's basic constituent parts, the most important being vendor and model.
One reason for doing this would be to use this information to lookup vendor-model specific device characteristics in a database. You can use also use user agent profiles to do this (for which I've developed other classes), but not all mobile phones have these, especially the older types. Another reason would be to detect if the visiting client is a mobile handset.
Only real mobile user-agent strings can be parsed succesfully by this class. Most WAP emulators are not supported because they usually don't use the same user-agent strings as the devices they emulate.
This class method constructs a new Mobile::UserAgent object. You can either pass a user-agent string as parameter or else let the constructor try to extract it from the HTTP_USER_AGENT environment variable.
The public object methods available are:
Returns true if the user-agent string passed into the constructor could be parsed, else false. If this method returns false, then it's probably not a mobile user agent string that was passed into the constructor.
Returns the user agent string as passed into the constructor or read from the environment variable HTTP_USER_AGENT.
Returns the vendor of the handset if success() returns true, else undef.
Returns the model of the handset if success() returns true, else undef.
Returns the version part, if any, of the parsed user-agent string, else undef. The version information is often not present or unreliable.
Determines if the parsed user-agent string belongs to an i-mode handset. Returns a boolean. Examples of such user-agent strings:
portalmmm/1.0 m21i-10(c10) portalmmm/1.0 n21i-10(c10) portalmmm/1.0 n21i-10(;ser123456789012345;icc1234567890123456789F) portalmmm/2.0 N400i(c20;TB) portalmmm/2.0 P341i(c10;TB) DoCoMo/1.0/modelname DoCoMo/1.0/modelname/cache DoCoMo/1.0/modelname/cache/unique_id_information DoCoMo/2.0 modelname(cache;individual_identification_information)
Determines if the parsed user-agent string has a Mozilla 'compatible' format. Returns a boolean. Examples of such user-agent strings:
Mozilla/4.1 (compatible; MSIE 5.0; Symbian OS; Nokia 3650;424) Opera 6.10 [en] Mozilla/4.0 (compatible; MSIE 6.0; Nokia7650) ReqwirelessWeb/2.0.0.0 Mozilla/1.22 (compatible; MMEF20; Cellphone; Sony CMD-Z5) Mozilla/1.22 (compatible; MMEF20; Cellphone; Sony CMD-Z5;Pz063e+wt16) Mozilla/2.0 (compatible; MSIE 3.02; Windows CE; PPC; 240x320) mozilla/4.0 (compatible;MSIE 4.01; Windows CE;PPC;240X320) UP.Link/5.1.1.5 Mozilla/4.0 (compatible; MSIE 4.01; Windows CE; PPC; 240x320) Mozilla/4.0 (compatible; MSIE 4.01; Windows CE; SmartPhone; 176x220) Mozilla/2.0 (compatible; MSIE 3.02; Windows CE; 240x320; PPC) Mozilla/2.0 (compatible; MSIE 3.02; Windows CE; Smartphone; 176x220; Mio8380; Smartphone; 176x220) Mozilla/4.0 (MobilePhone SCP-8100/US/1.0) NetFront/3.0 MMP/2.0 Mozilla/2.0(compatible; MSIE 3.02; Windows CE; Smartphone; 176x220) Mozilla/4.1 (compatible; MSIE 5.0; Symbian OS Series 60 42) Opera 6.0 [fr] Mozilla/SMB3(Z105)/Samsung UP.Link/5.1.1.5
Determines if the parsed user-agent string has a standard vendor-model/version format. Returns a boolean. Examples of such user-agent strings:
Nokia8310/1.0 (05.57) NokiaN-Gage/1.0 SymbianOS/6.1 Series60/1.2 Profile/MIDP-1.0 Configuration/CLDC-1.0 SAGEM-myX-6/1.0 UP.Browser/6.1.0.6.1.c.3 (GUI) MMP/1.0 UP.Link/1.1 SAMSUNG-SGH-A300/1.0 UP/4.1.19k SEC-SGHE710/1.0
Determines if the parsed user-agent string has a non-standard or messed up (to put it in general-public-friendly words) format. Returns a boolean. Examples of such user-agent strings:

Returns the maximum i-mode cache data size in kb's of the user agent if it is an i-mode user-agent, else undef.
Returns the screen dimensions in the format wxh if this information was parsed from the user agent string itself, else undef. Only a few handsets contain this information in the user-agent string such as these that use operating systems from the company I hate most:
mozilla/2.0 (compatible; MSIE 3.02; Windows CE; PPC; 240x320) mozilla/4.0 (compatible;MSIE 4.01; Windows CE;PPC;240X320) UP.Link/5.1.1.5 Mozilla/4.0 (compatible; MSIE 4.01; Windows CE; PPC; 240x320) Mozilla/4.0 (compatible; MSIE 4.01; Windows CE; SmartPhone; 176x220) Mozilla/2.0 (compatible; MSIE 3.02; Windows CE; 240x320; PPC) Mozilla/2.0 (compatible; MSIE 3.02; Windows CE; Smartphone; 176x220; Mio8380; Smartphone; 176x220) Mozilla/4.0 (MobilePhone SCP-8100/US/1.0) NetFront/3.0 MMP/2.0 Mozilla/2.0(compatible; MSIE 3.02; Windows CE; Smartphone; 176x220)
Determines if the parsed user-agent string belongs to a Symbian OS Series 60 handset. Examples of such user-agent strings:
NokiaN-Gage/1.0 SymbianOS/6.1 Series60/1.2 Profile/MIDP-1.0 Configuration/CLDC-1.0 Mozilla/4.1 (compatible; MSIE 5.0; Symbian OS Series 60 42) Opera 6.0 [fr] Nokia6600/1.0 (4.09.1) SymbianOS/7.0s Series60/2.0 Profile/MIDP-2.0 Configuration/CLDC-1.0
Co-developers are very welcome. Please let me know if you want to help maintain this class. Since the mobile world is evolving rapidly, this class will have to keep up with it when new vendors and standards emerge in user-agent strings.
