　　2) Text messaging with PHP using the TextMagic API ——使用TextMagic API 獲取PHP Test信息

　　TextMagic引入強大的核心API，可輕鬆將SMS發送到手機。該API是須要付費。程序員

 
        the TextMagic PHP lib 
       
        require 
        (

　　3) Get info about your memory usage——獲取內存使用率

　　這段代碼幫助你獲取內存使用率。web

 
        echo 
        "Initial: " 
        .memory_get_usage(). 
        " bytes \n" 
        ; 
       
        /* prints 
       
        Initial: 361400 bytes 
       
        */ 
       
        // let's use up some memory 
       
        for 
        ( 
        $i 
        = 0;  
        $i 
        < 100000;  
        $i 
        ++) { 
       
        $array 
        []= md5( 
        $i 
        ); 
       
        } 
       
        // let's remove half of the array 
       
        for

        /* prints 
       
        Peak: 13687072 bytes 
       
        */

　　4) Display source code of any webpage——查看任意網頁源代碼

　　若是你想查看網頁源代碼，那麼只需更改第二行的URL，源代碼就會在網頁上顯示出。api

 
        <?<span id= 
        "2_nwp" 
        style= 
        "width: auto; height: auto; float: none;" 
        ><a id= 
        "2_nwl" 
        href= 
        "http://cpro.baidu.com/cpro/ui/uijs.php?adclass=0&app_id=0&c=news&cf=1001&ch=0&di=128&fv=19&is_app=0&jk=c4615ba7eed770c&k=php&k0=php&kdi0=0&luki=9&mcpm=0&n=10&p=baidu&q=06011078_cpr&rb=0&rs=1&seller_id=1&sid=c77ed7eba15460c&ssp2=1&stid=0&t=tpclicked3_hc&td=1922429&tu=u1922429&u=http%3A%2F%2Fwww%2Eadmin10000%2Ecom%2Fdocument%2F4038%2Ehtml&urlid=0" 
        target= 
        "_blank" 
        mpid= 
        "2" 
        style= 
        "text-decoration: none;" 
        ><span style= 
        "color:#0000ff;font-size:14px;width:auto;height:auto;float:none;" 
        >php</span></a></span> // display source code  
        $lines 
        = file( 
        'http://google.com/' 
        );  
        foreach 
        ( 
        $lines 
        as 
        $line_num 
        =>  
        $line 
        ) {  
       
 
             
        // loop thru each line and prepend line numbers 
       
 
             
        echo 
        "Line #{$line_num} : " 
        . htmlspecialchars( 
        $line 
        ) . " 
       
 
        \n"; 
       
 
        } 
       

　　5) Create data uri’s——建立數據uri

經過使用此代碼，你能夠建立數據Uri，這對在HTML/CSS中嵌入圖片很是有用，可幫助節省HTTP請求。數組

 
        function 
        data_uri( 
        $file 
        ,  
        $mime 
        ) { 
       
        $contents 
        = 
        file_get_contents 
        ( 
        $file 
        ); 
       
        $base64 
        = 
        base64_encode 
        ( 
        $contents 
        ); 
       
        echo 
        "data:$mime;base64,$base64" 
        ; 
       
        }

　　6) Detect location by IP——經過IP檢索出地理位置

　　這段代碼幫助你查找特定的IP，只需在功能參數上輸入IP，就可檢測出位置。瀏覽器

 
        function 
        detect_city( 
        $ip 
        ) { 
       

           
       
 
                 
        $default 
        =  
        'UNKNOWN' 
        ; 
       

           
       
 
                 
        if 
        (! 
        is_string 
        ( 
        $ip 
        ) ||  
        strlen 
        ( 
        $ip 
        ) < 1 ||  
        $ip 
        ==  
        '127.0.0.1' 
        ||  
        $ip 
        ==

　　7) Detect browser language——查看瀏覽器語言

　　檢測瀏覽器使用的代碼腳本語言。服務器

 
        function 
        get_client_language( 
        $availableLanguages 
        ,  
        $default 
        = 
        'en' 
        ){ 
       
        if 
        (isset( 
        $_SERVER 
        [ 
        'HTTP_ACCEPT_LANGUAGE' 
        ])) { 
       
        $langs 
        = 
        explode 
        ( 
        ',' 
        , 
        $_SERVER 
        [ 
        'HTTP_ACCEPT_LANGUAGE' 
        ]); 
       
        foreach 
        ( 
        $langs 
        as 
        $value 
        ){ 
       
        $choice 
        = 
        substr 
        ( 
        $value 
        ,0,2); 
       
        if 
        (in_array( 
        $choice 
        ,  
        $availableLanguages 
        )){ 
       
        return 
        $choice 
        ; 
       
        } 
       
        } 
       
        }  
       
        return 
        $default 
        ; 
       
        }

　　8) Check if server is HTTPS——檢測服務器是不是HTTPS

 
        if 
        ( 
        $_SERVER 
        [ 
        'HTTPS' 
        ] !=  
        "on" 
        ) {  
       
        echo 
        "This is not HTTPS" 
        ; 
       
        } 
        else 
        { 
       
        echo 
        "This is HTTPS" 
        ; 
       
        }

　　9) Generate CSV file from a PHP array——在PHP數組中生成.csv 文件

 
        function 
        generateCsv( 
        $data 
        ,  
        $delimiter 
        =  
        ',' 
        ,  
        $enclosure 
        =  
        '"' 
        ) {
