PHP Common Small program code snippets _php Tips

This article is an example of the code snippet commonly used in PHP. Share to everyone for your reference, specific as follows:

1. Calculate the difference of two times a few days

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

The PHP time and date function above Strtotime has turned the string date into a timestamp, so as long as you subtract two values and then turn the seconds into days, the comparison is simple, as follows:

$days =round (($enddate-$startdate)/3600/24);
Echo $days; Days for the day;

2. Paging

/** * Author Jackluo * $url address, total $count, $page current face, $Pagesize paging size/function Page_paper ($url, $count, $page, $pagesize) {
  $allpage = Ceil ($count/$pagesize); if ($allpage <=3) {for ($i =1; $i <= $allpage; $i + +) {if ($i = = $page) {echo ' <a href= '. $url. '
    &page= '. $page. ' "class=" PAGE_OVR ">". $i. ' </a> '; }else{Echo ' <a href= '. $url. '
    &page= '. $i. ' > '. $i. ' </a> ';
   }}}else{$currentpage = $allpage-$page; if ($page <=3) {for ($i =1; $i <= $page; $i + +) {if ($i = = $page) {echo ' <a href= '. $url. '
     &page= '. $i. ' "class=" PAGE_OVR ">". $i. ' </a> '; }else{Echo ' <a href= '. $url. '
     &page= '. $i. ' > '. $i. ' </a> '; }//Three if ($currentpage <=3) {for ($i = ($page + 1); $i <= $allpage; $i + +) {echo ' <a href= '. $url.
     ' &page= '. $i. ' > '. $i. ' </a> '; }else{for ($i = ($page + 1), $i <= ($page +3), $i + +) {echo ' <a href= '. $url. ' &page= '. $i. ' > '. $i. ' </a> '; }}else{//Top three for ($i = ($page-3); $i <= $page; $i + +) {if ($i = = $page) {echo ' <a href= '. $url.
     ' &page= '. $i. ' "class=" PAGE_OVR ">". $i. ' </a> '; }else{Echo ' <a href= '. $url. '
     &page= '. $i. ' > '. $i. ' </a> '; } if ($currentpage <=3) {for ($i = ($page + 1); $i <= $allpage; $i + +) {echo ' <a href= '. $url. '
     &page= '. $i. ' > '. $i. ' </a> '; }else{//After three for ($i = ($page + 1); $i <= ($page +3); $i + +) {echo ' <a href= '. $url. '
     &page= '. $i. ' > '. $i. ' </a> ';

 }
    }
   }
  }
}

3. Get the place where the mobile phone belongs (have time, can write a mobile platform)

Get cell phone Attribution
function Phonenumberinfo ($phone) {
  $list = array ();
  $soap =  new SoapClient (' http://webservice.webxml.com.cn/WebServices/MobileCodeWS.asmx?wsdl ');
  $result = (array) $soap->getmobilecodeinfo (Array (
    ' Mobilecode ' => $phone
  ));
  List ($moblie, $location, $lbs) = Explode (', $result [' Getmobilecodeinforesult ']);
  if ($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;
  }

I hope this article will help you with the PHP program design.
