  此中将收藏我在工作中用到的一些PHP函数。有自己写的,也会有网上收集的。此文不断更新中
1.打印数组函数 

function  _print( $array )
{
     echo  ( "

 " );    <br>         print_r ( $array );    <br>     echo  ( " 
Copy after login
" );
}

2.截取字串

func_chgtitle
function func_chgtitle($str,$len) 

    if(strlen($str)>$len)
    {
        $tmpstr = "";
        $strlen = $len;
        for($i = 0; $i         {
            if(ord(substr($str, $i, 1)) > 0xa0) 
            {
               $tmpstr .= substr($str, $i, 2);
               $i++;
            } 
            else
               $tmpstr .= substr($str, $i, 1);
        }
        return $tmpstr."";
    }
    else
    {
        return $str;
    }
}

3.加载文件

loadFile
function loadFile($filepath)
{
    $filecontent = "";
    $fptr = fopen($filepath,"r");
    if ($fptr)
    {
    while ($content = fgets($fptr,4096))
        {
        $filecontent .= $content;
    }
    fclose($fptr);
    }
    return $filecontent;
}

4.下载文件

downloadFile
function downloadFile($path,$fileInfo)
{
    $target_file = $path.$fileInfo['fileid'];
    $file_content = loadFile($target_file);
    header("Content-Disposition: attachment; filename=".$fileInfo['filename']);
    header("Content-type: ".$fileInfo['filetype']);
    header("Content-Length: ".$fileInfo['filesize']);
    echo $file_content;
}

5.数组排序

*/
     function  sysSortArray( $ArrayData , $KeyName1 , $SortOrder1   =   " SORT_ASC " , $SortType1   =   " SORT_REGULAR " )
    {    
         if ( ! is_array ( $ArrayData ))
        {
             return   $ArrayData ;
        }
 
         //  Get args number.
         $ArgCount   =   func_num_args ();
 
         //  Get keys to sort by and put them to SortRule array.
             for ( $I   =   1 ; $I               {
                 $Arg   =   func_get_arg ( $I );
             if ( ! eregi ( " SORT " , $Arg ))
            {
                 $KeyNameList []  =   $Arg ;
                 $SortRule []     =   ' $ ' . $Arg ;
               }
             else
            {
                 $SortRule []     =   $Arg ;
            }
        }
 
         //  Get the values according to the keys and put them to array.
             foreach ( $ArrayData   AS   $Key   =>   $Info )
        {
             foreach ( $KeyNameList   AS   $KeyName )
            {
                ${ $KeyName }[ $Key ]  =   $Info [ $KeyName ];
            }
        }    
 
         //  Create the eval string and eval it.
         if ( count ( $ArrayData ) > 0 )
        {
             $EvalString   =   ' array_multisort( ' . join ( " , " , $SortRule ) . ' ,$ArrayData); ' ;
             eval  ( $EvalString );
        }
         return   $ArrayData ;
    }
