Copy code The code is as follows:

function get_php_url(){
if(! empty($_server["REQUEST_URI"])){
$scriptName = $_SERVER["REQUEST_URI"];
$nowurl = $scriptName;
}else{
                $scriptName = $_SERVER[ "PHP_SELF"];
if (Empty ($ _ server ["query_string"]) $ nowurl = $ scriptname;
Else $ nowurl = $ scriptname. "". Erver ["query_string"];
} Return $ nowurl;
}

// Turn the full -angle number into a half -angle number

Copy code 🎜> The code is as follows:

function GetAlabNum($fnum){

$nums = array("0","1","2","３","４"," 5","6","7","8","9");
$fnums = "0123456789";
for($i=0;$i<=9;$i++) $ fnum = str_replace($nums[$i],$fnums[$i],$fnum);
$fnum = ereg_replace("[^0-9.]|^0{1,}","", $fnum);
if($fnum=="") $fnum=0;
return $fnum;
}


//Remove HTML tags

Copy code The code is as follows:

function Text2Html($txt){

$txt = str_replace(" ","　",$ txt);
$txt = str_replace("<","<",$txt);
$txt = str_replace(">",">",$txt);
$txt = preg_replace("/[rn]{1,}/isU","
rn",$txt);
return $txt;
}


/ /Clear HTML tag

Copy code The code is as follows:

function ClearHtml($str){
         str = str_replace('<','<',$str);
$str = str_replace('>','>',$str);
return $str;
}


//Convert relative path to absolute path

Copy code The code is as follows:

function relative_to_absolute($content, $feed_url) {  
    preg_match('/(http|https|ftp):///', $feed_url, $protocol);  
    $server_url = preg_replace("/(http|https|ftp|news):///", "", $feed_url);  
    $server_url = preg_replace("//.*/", "", $server_url);  

    if ($server_url == '') {  
        return $content;  
    }  

    if (isset($protocol[0])) {  
        $new_content = preg_replace('/href="//', 'href="'.$protocol[0].$server_url.'/', $content);  
        $new_content = preg_replace('/src="//', 'src="'.$protocol[0].$server_url.'/', $new_content);  
    } else {  
        $new_content = $content;  
    }  
    return $new_content;  
}  

//取得所有链接

复制代码 代码如下:

function get_all_url($code){  
        preg_match_all('/"' ]+)["|']?s*[^>]*>([^>]+)/i',$code,$arr);  
        return array('name'=>$arr[2],'url'=>$arr[1]);  
} 

//HTML表格的每行转为CSV格式数组 

复制代码 代码如下:

function get_tr_array($table) { 
        $table = preg_replace("']*?>'si",'"',$table); 
        $table = str_replace("",'",',$table); 
        $table = str_replace("","{tr}",$table); 
function get_tr_array($table) { 
        $table = preg_replace("']*?>'si",'"',$table); 
        $table = str_replace("",'",',$table); 
        $table = str_replace("","{tr}",$table); 
        //去掉 HTML 标记  
        $table = preg_replace("'<[/!]*?[^<>]*?>'si","",$table); 
        //去掉空白字符  
        $table = preg_replace("'([rn])[s]+'","",$table);
        $table = str_replace(" ","",$table);
        $table = str_replace(" ","",$table);

        $table = explode(",{tr}",$table);
        array_pop($table);
        return $table;
}

//将HTML表格的每行每列转为数组，采集表格数据

复制代码 代码如下:

function get_td_array($table) { 
        $table = preg_replace("']*?>'si","",$table); 
        $table = preg_replace("']*?>'si","",$table); 
        $table = preg_replace("']*?>'si","",$table); 
        $table = str_replace("","{tr}",$table); 
        $table = str_replace("","{td}",$table); 
        //去掉 HTML 标记  
        $table = preg_replace("'<[/!]*?[^<>]*?>'si","",$table); 
        //去掉空白字符   
        $table = preg_replace("'([rn])[s]+'","",$table); 
        $table = str_replace(" ","",$table); 
        $table = str_replace(" ","",$table); 

        $table = explode('{tr}', $table); 
        array_pop($table); 
        foreach ($table as $key=>$tr) { 
                $td = explode('{td}', $tr); 
                array_pop($td); 
            $td_array[] = $td; 
        } 
        return $td_array; 
} 

//返回字符串中的所有单词 $distinct=true 去除重复

复制代码 代码如下:

function split_en_str($str,$distinct=true) { 
        preg_match_all('/([a-zA-Z]+)/',$str,$match); 
        if ($distinct == true) { 
                $match[1] = array_unique($match[1]); 
        } 
        sort($match[1]); 
        return $match[1]; 
}
