function Getpic ($url, $dir, $name) {
Gets the URL file and then stores it in the Dir directory, with name as the filename.
If the default file name, the original file name is retained.
$tmp =split ("/", $url);
$fname = $tmp [Count ($tmp) -1];//gets the file name
if (empty ($name)) {
$name = $fname;//Set the filename.
}else{//determines if the file's extension has been changed, and if so, the file's own extension.
$tmp 1=split ("\.", $fname);
$tmp 2=split ("\.", $name);
if (strcmp ($tmp 1[1], $tmp 2[1])!=0) $name = $tmp 2[0]. "." $tmp 1[1];
}
if (Strstr ($dir, "\ \")) {//description is a directory in Windows environment
if (substr ($dir, -2) = = "\") $file = $dir. $name; else $file = $dir. " \ ". $name;
}else{
if (substr ($dir, "/")) {//description is a directory in the Linux environment
if (substr ($dir, -1) = = "/") $file = $dir. $name; else $file = $dir. " /". $fname;
}
else{//gave an illegal directory, the function exited
echo "Error directory!";
return;
}
}
if (!) ( File_exists ("$dir") && is_dir ("$dir")) {//If directory does not exist, create directory
mkdir ($dir, 0777);
}
if (file_exists ($file)) return;//If the file exists, abort the operation
$fpo =fopen ($file, "WB");
if (! $fpo) {
echo "Sorry,create file: $file failure! Check your right! ";
return;
}
$num = 0;
do{
$num + +;
$FPI =fopen ($url, "R");
if (! $fpi) echo "Open remote file Falure ... Retry!\r\n ";
}while (! $FPI && $num <3); The file tries to open up to three times, and then exits.
if (!FPI) {
echo "The network is Buzy or bad url!";
return;
}else echo "Open file ok! Now transfer ... ";
while (!feof ($FPI)) {
$cont =fread ($FPI, 128);
Fwrite ($fpo, $cont, 128);
}
Fclose ($FPI);
Fclose ($FPO);
echo "success!";
}
