Hi,
$string doesn't have any spaces in it, so after you do explode:
$string_arr=explode(" ",$string);
$string_arr only has one element in it ($string_arr[0]).
You are trying to access elements 0,1,2,3,4,5,6,7,8,9, but 1-9 don't exist when
there is no space character in $string.
You could change this:
for($i=0;$i<$wordnum;$i++)
{
$re_string=" ".$string_arr[$i];
$str=$re_string;
print $str;
}
into this:
for($i=0;$i<$wordnum;$i++)
{
// nothing to do if this element of $string_arr
// does not exist!
if(!isset($string_arr[$i]))
break; // break out of loop
$re_string=" ".$string_arr[$i];
$str=$re_string;
print $str;
}
Or if you are unfamiliar with 'break', you could use this:
for($i=0;$i<$wordnum;$i++)
{
if(isset($string_arr[$i])) {
$re_string=" ".$string_arr[$i];
$str=$re_string;
print $str;
}
}
regards,
Peter
