復(fù)制代碼 代碼如下:
function _print($array)
{
echo ("<pre>");
print_r($array);
echo ("</pre>");
}
2.截取字串
復(fù)制代碼 代碼如下:
func_chgtitle
function func_chgtitle($str,$len)
{
if(strlen($str)>$len)
{
$tmpstr = "";
$strlen = $len;
for($i = 0; $i < $strlen; $i++)
{
if(ord(substr($str, $i, 1)) > 0xa0)
{
$tmpstr .= substr($str, $i, 2);
$i++;
}
else
$tmpstr .= substr($str, $i, 1);
}
return $tmpstr."";
}
else
{
return $str;
}
}
3.加載文件
復(fù)制代碼 代碼如下:
loadFile
function loadFile($filepath)
{
$filecontent = "";
$fptr = fopen($filepath,"r");
if ($fptr)
{
while ($content = fgets($fptr,4096))
{
$filecontent .= $content;
}
fclose($fptr);
}
return $filecontent;
}
4.下載文件
downloadFile
復(fù)制代碼 代碼如下:
function downloadFile($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.數(shù)組排序
復(fù)制代碼 代碼如下:

*
*
* Sort an two-dimension array by some level two items use array_multisort() function.

* @author Chunsheng Wang <wwccss@263.NET>
* @param array $ArrayData the array to sort.

*/
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 < $ArgCount;$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;
}
