PHP Common function Encapsulation

This article is to share the content of PHP commonly used function encapsulation, interested friends can have a look

1. Determine if the request is HTTP or HTTPS

$http _type = ((Isset ($_server[' https ") && $_server[' https '] = = ' on ') | | (Isset ($_server[' Http_x_forwarded_proto ') && $_server[' http_x_forwarded_proto '] = = ' https ')) ? ' https://': '/HTTP ';

2. Text Editor Intercept:

/** * Capture text in Rich text as part of * @param $content * @return string */function html_substr_content ($content, $length =100) {    $ Content = Htmlspecialchars_decode ($content);      Convert some of the predefined HTML entities to characters      $content = Str_replace ("", "", $content);     Replace the space with an empty      $content = Strip_tags ($content);                 The function strips HTML, XML, and PHP tags from the string to get plain text content      $con = mb_substr ($content, 0, $length, "Utf-8");   Returns the character of the first 100 string length in the string return      $con;}

3. Delete an empty array in the array

Delete empty array in data (search in common) function Where_data ($data) {    foreach ($data as $k + $v) {        if (empty ($v) && $v! = ' 0 ' ) {            unset ($data [$k]);        }    }    return $data;}

4. Converting an array into an object

/** * Array to Object * @param object $obj objects * @return array */function array2object_l ($array) {    if (Is_array ($array)) {        $obj = new StdClass ();        foreach ($array as $key + $val) {            $obj $key = $val;        }    } else {        $obj = $array;    }    return $obj;}

5.xml Conversion Array

The XML converts an array of functions function Xmltoarray ($simpleXmlElement) {    $simpleXmlElement = (array) $simpleXmlElement;    foreach ($simpleXmlElement as $k = + $v) {        if ($v instanceof simplexmlelement | | is_array ($v)) {            $simpleXmlEle ment[$k] = Xmltoarray ($v);        }    }    return $simpleXmlElement;}

6. Generate a unique order number

function Generate_out_trade_no () {    $a = date (' Ymd '). substr (Implode (NULL, Array_map (' Ord ', Str_split (substr ( Uniqid (), 7, 1)), 0, 8);    Return ' F_ '. $a. Rand (10000000, 99999999);}

7. Determine whether it is mobile or PC-side

* * To determine if the current user is the PC or the phone end returns true for the phone side false for the PC side * @return Boolean *//** * Whether the Mobile Access access * * @return bool */function    IsMobile () {///If there is http_x_wap_profile, it must be the mobile device if (Isset ($_server[' http_x_wap_profile ')) return true; If the VIA information contains WAP, it must be a mobile device, some service associations block the information if (Isset ($_server[' Http_via ')) {//Cannot find for flase, otherwise true return St Ristr ($_server[' Http_via '), "WAP")?    True:false; }//Brain residue method, determine the mobile phone sent by the client flag, compatibility needs to be improved if (Isset ($_server[' http_user_agent ')) {$clientkeywords = array (' Nokia ', ' Sony ', ' Ericsson ', ' mot ', ' Samsung ', ' HTC ', ' SGH ', ' lg ', ' sharp ', ' sie-', ' Philips ', ' Panasonic ', ' Alcatel ', ' Lenovo ', ' iphone ', ' ipod ', ' blackberry ', ' Meizu ', ' Android ', ' NetFront ', ' Symbian ', ' UCWeb ', ' windowsce ', ' palm ', ' Operamini ', '        Operamobi ', ' Openwave ', ' nexusone ', ' cldc ', ' MIDP ', ' wap ', ' mobile '; Look for the keyword if (Preg_match ("/(") of the phone's browser from Http_user_agent. Implode (' | ', $clientkeywords).    ")/I", Strtolower ($_server[' http_user_agent '))) return true; }    //protocol method, because there may be inaccuracies, put to the Last Judgment if (Isset ($_server[' http_accept ')) {//If only WML is supported and HTML is not supported that must be mobile device//If WML and H are supported TML but WML before HTML is the mobile device if ((Strpos ($_server[' http_accept '), ' VND.WAP.WML ')!== false) && (Strpos ($_server[' H Ttp_accept '], ' text/html ') = = = False | |        (Strpos ($_server[' http_accept '), ' vnd.wap.wml ') < Strpos ($_server[' http_accept '], ' text/html '))))        {return true; }} return false;}
