I will write a small program to use php to determine whether the terminal is a mobile phone or a computer to visit the website. if you are interested, refer to the following code. I hope to help you learn php:
The code is as follows:
Function check_wap (){
If (isset ($ _ SERVER ['http _ VIA ']) return true;
If (isset ($ _ SERVER ['http _ X_NOKIA_CONNECTION_MODE ']) return true;
If (isset ($ _ SERVER ['http _ X_UP_CALLING_LINE_ID ']) return true;
If (strpos (strtoupper ($ _ SERVER ['http _ ACCEPT ']), "VND. WAP. WML")> 0 ){
// Check whether the browser/gateway says it accepts WML.
$ Br = "WML ";
} Else {
$ Browser = isset ($ _ SERVER ['http _ USER_AGENT '])? Trim ($ _ SERVER ['http _ USER_AGENT ']): '';
If (empty ($ browser) return true;
$ Mobile_ OS _list = array ('Google Wireless Transcoder ', 'windows CE', 'windowsce ', 'symbian', 'Android', 'armv6l', 'armv5 ', 'mobile ', 'cento', 'moyun', 'avantgo ', 'Opera Mobi', 'j2's/MIDP ', 'Smartphone', 'Go. web ', 'Palm', 'ipaq ');
$ Mobile_token_list = array ('Profile/MIDP ', 'configuration/CLDC-', '000000', '000000', '000000', '000000 ', '1970*240 ', '1970*320', 'Up. browser ', 'Up. link ', 'symbian OS', 'palmos ', 'pocketpc', 'sonyericsson', 'Nokia ', 'BlackBerry', 'Vodafone', 'benq ', 'novarra-vision', 'Iris', 'netfront', 'HTC _ ', 'xda _', 'Samsung-sgh', 'wapaka ', 'docomo ', 'iPhone ', 'iPod ');
$ Found_mobile = checkSubstrs ($ mobile_ OS _list, $ browser) |
CheckSubstrs ($ mobile_token_list, $ browser );
If ($ found_mobile)
$ Br = "WML ";
Else $ br = "WWW ";
}
If ($ br = "WML "){
Return true;
} Else {
Return false;
}
}
Function checkSubstrs ($ list, $ str ){
$ Flag = false;
For ($ I = 0; $ I If (strpos ($ str, $ list [$ I])> 0 ){
$ Flag = true;
Break;
}
}
Return $ flag;
}
If (check_wap ()){
Echo "wap ";
} Else {
Echo "web ";
}
?>


Code 2:

The code is as follows:
Header ("Content-type: text/html; charset = utf-8 ");
Function is_mobile (){
$ User_agent = $ _ SERVER ['http _ USER_AGENT '];
$ Mobile_agents = Array ("240x320", "acer", "ACO on", "acs-", "abacho", "ahong", "airness", "alcatel ", "amoi", "android", "anywhereyougo.com", "applewebkit/525", "applewebkit/532", "asus", "audio", "au-mic ", "avantogo", "becker", "benq", "bilbo", "bird", "blackberry", "blazer", "bleu", "cdm -", "compal", "coolpad", "danger", "dbtel", "dopod", "elaine", "eric", "etouch", "fly ", "fly _", "fly-", "go. web "," goodaccess "," gradiente "," grundig "," haier "," hedy "," hitachi "," htc "," huawei "," Huchison ", "inno", "ipad", "ipaq", "ipod", "jbrowser", "kddi", "kgt", "kwc", "lenovo", "lg ", "lg2", "lg3", "lg4", "lg5", "lg7", "lg8", "lg9", "lg-", "lge -", "lge9", "longcos", "maemo", "mercator", "meridian", "micromax", "midp", "mini", "mitsu", "mmm ", "mmp", "mobi", "mot-", "moto", "nec-", "netfront", "newgen", "nexian", "nf-browser ", "nintendo", "nitro", "nokia", "nook", "novarra", "obigo", "palm", "panasonic", "pantech", "philips ", "phone", "pg-", "playstation", "pocket", "pt-", "qc-", "qtek", "rover", "sagem ", "sama", "samu", "sanyo", "samsung", "sch-", "scooter", "sec-", "sendo", "sgh -", "sharp", "siemens", "sie-", "softbank", "sony", "spice", "sprint", "spv", "symbian ", "tablet", "talkabout", "tcl-", "teleca", "telit", "tianyu", "tim-", "toshba", "tsm ", "up. browser "," utec "," utstar "," verykool "," virgin "," vk-"," voda "," voxtel "," vx "," wap ", "wellco", "wig browser", "wii", "windows ce", "wireless", "xda", "xde", "zte ");
$ Is_mobile = false;
Foreach ($ mobile_agents as $ device ){
If (stristr ($ user_agent, $ device )){
$ Is_mobile = true;
Break;
}
}
Return $ is_mobile;
}
If (is_mobile ()){
Echo "mobile phone ";
} Else {
Echo "computer ";
}
