Look at the manuel:
If filename is not a valid upload file, then no action will occur, and
move_uploaded_file() will return FALSE.
If filename is a valid upload file, but cannot be moved for some reason, no
action will occur, and move_uploaded_file() will return FALSE. Additionally,
a warning will be issued.
So,
if(move_uploaded_file($tmp,$target)){
//will execute code on succes: succesfull upload & move.
} else {
//error with moving or uploading
}
The following will work, but more verbose:
$checkj = move_uploaded_file($tmp,$target);
if($check){
//will execute code on succes: succesfull upload & move.
} else {
//error with moving or uploading
}
The following will not work, because the file already has been moved:
move_uploaded_file($tmp,$target); //this works
if(move_uploaded_file($tmp,$target)){ // this returns false: the file has
already been moved
//will execute code on succes: succesfull upload & move.
} else {
//error with moving or uploading
}
