PHP small program code segments, PHP common program code segments _ PHP Tutorial

Common small program code segments in PHP and common program code segments in PHP. Common small program code segments in PHP, common program code segments in PHP this article describes common small program code segments in PHP. I would like to share with you for your reference. The details are as follows: 1. calculate the common small program code segments of PHP at two times, and the common PHP program code segments.

This example describes common small program code segments in PHP. We will share this with you for your reference. The details are as follows:

1. calculate the time difference between the two days

$startdate=strtotime("2009-12-09");$enddate=strtotime("2009-12-05");

The above php time and date function strtotime has converted the string date into a timestamp, so that we only need to subtract the two values and then convert the second to the day. the comparison is simple, as shown below:

$ Days = round ($ enddate-$ startdate)/3600/24); echo $ days; // days indicates the number of days;

2. paging

/*** Author jackluo * $ url address, $ count total, $ page current surface, $ Pagesize page size */function page_paper ($ url, $ count, $ page, $ pagesize) {$ allpage = ceil ($ count/$ pagesize); if ($ allpage <= 3) {for ($ I = 1; $ I <= $ allpage; $ I ++) {if ($ I = $ page) {echo ''. $ I. '';} else {echo ''. $ I. '';}} else {$ currentpage = $ allpage-$ page; if ($ page <= 3) {for ($ I = 1; $ I <= $ page; $ I ++) {if ($ I = $ page) {echo ''. $ I. '';} else {echo ''. $ I. '';} // the last three if ($ currentpage <= 3) {for ($ I = ($ page + 1); $ I <= $ allpage; $ I ++) {echo ''. $ I. '';}} else {for ($ I = ($ page + 1); $ I <= ($ page + 3); $ I ++) {echo ''. $ I. ''; }}} else {// The first three for ($ I = ($ page-3); $ I <= $ page; $ I ++) {if ($ I = $ page) {echo ''. $ I. '';} else {echo ''. $ I. '';}} if ($ currentpage <= 3) {for ($ I = ($ page + 1); $ I <= $ allpage; $ I ++) {echo ''. $ I. '';}} else {// The last three for ($ I = ($ page + 1); $ I <= ($ page + 3); $ I ++) {echo ''. $ I. '';}}}}}

3. get the mobile phone home location (if you have time, you can write a mobile platform)

// Obtain the function phonenumberinfo ($ phone) {$ list = array (); $ soap = new SoapClient ('http: // webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx? Wsdl '); $ result = (array) $ soap-> getMobileCodeInfo (array ('lelecode' => $ phone); list ($ moblie, $ location, $ lbs) = explode ('', $ result ['getlelecodeinforesult ']); if ($ lbs) {$ type = array ('mobile', 'telecom ', 'unicom '); foreach ($ type as $ key => $ value) {$ ps = strpos ($ lbs, $ value); if ($ ps) {$ procver = substr ($ lbs, 0, $ ps); $ list ['Province '] = $ procver; $ list ['operator'] = $ value; $ list ['city'] = $ location; $ list ['type'] = $ key; break;} return $ list ;}}
