Common custom Methods in PHP

1. Month Display

/** month Displays 
*   @param  int    $m       1-12 
*   @param  int    $type    0:long 1:short (default 2:chinese 
*   @return String *
/function Format_month ($m, $type =0) {  
    $month = array (  
                Array (', ' January ', ' February ', ' March ', ' April ', ' may ', ' June ', ' July ', ' August ', ' September ', ' October ', ' November ', ' D Ecember '), Array (', ' Feb ', ', ', ', ', ', ', ', ', ', ', ', ', ' Apr ', ' may

            ;  
    return $month [$type] [$m];  
}

2. Filter string, retain UTF8 alphanumeric Chinese and some symbols

/** filter string, preserving UTF8 alphanumeric characters in Chinese and partial symbols * @param string $OSTR * @return string/function Filter_utf8_char ($OSTR) {PR 
    Eg_match_all ('/[\x{ff00}-\x{ffef}|\x{0000}-\x{00ff}|\x{4e00}-\x{9fff}]+/u ', $ostr, $matches);  
    $str = Join (' ", $matches [0]);  
        if ($str = = ") {//contains special characters need to be handled $returnstr = ';  
        $i = 0;  
        $str _length = strlen ($OSTR);  
            while ($i <= $str _length) {$temp _str = substr ($ostr, $i, 1);  
            $ascnum = Ord ($temp _str);  
                if ($ascnum >=224) {$returnstr = $returnstr. substr ($ostr, $i, 3);  
            $i = $i + 3;  
                }elseif ($ascnum >=192) {$returnstr = $returnstr. substr ($ostr, $i, 2);  
            $i = $i + 2;  
                }elseif ($ascnum >=65 && $ascnum <=90) {$returnstr = $returnstr. substr ($ostr, $i, 1);  
            $i = $i + 1; }elseif ($ascnum >=128 && $ascnum <=191) {//special wordsCharacter $i = $i + 1;  
                }else{$returnstr = $returnstr. substr ($ostr, $i, 1);  
            $i = $i + 1;  
        }} $str = $returnstr;
        Preg_match_all ('/[\x{ff00}-\x{ffef}|\x{0000}-\x{00ff}|\x{4e00}-\x{9fff}]+/u ', $str, $matches);  
    $str = Join (' ", $matches [0]);  
return $str; }

3. Binary Stream Generation file

/** binary Stream Generation file 
*   $_post cannot interpret binary streams, requiring $GLOBALS [' http_raw_post_data '] or php://input 
*   $GLOBALS [' Http_ Raw_post_data '] and php://input are not available for Enctype=multipart/form-data 
*   @param    String    $file   The file path to be generated 
*   @return   boolean
/function Binary_to_file ($file) {  
    $content = $GLOBALS [' Http_raw _post_data '];  Requires php.ini to set  
    if (empty ($content)) {  
        $content = file_get_contents (' php://input ');    Do not need php.ini settings, memory pressure small  
    }  
    $ret = File_put_contents ($file, $content, true);  
    return $ret;  
}
