1.打印数组函数
function _print( $array )
{
echo (
);
print_r ( $array );
echo (
);
} 2.截取字串
func_chgtitle
function func_chgtitle($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
