Script error under PHP 4.3.3

[Andrew Banks]

Could anyone identify why the following script is giving me various errors
under php 4.3.3. It worked fine on previous versions.

function cut_string($string,$wordnum,$trail)
{
$string_arr=explode(" ",$string);
for($i=0;$i<$wordnum;$i++)
{
$re_string.= " ".$string_arr[$i];
}
$str= $re_string.$trail;
print $str;
}

Thanks in advance

Post the 'various errors'.
function cut_string($string,$wordnum,$trail)
{
$string_arr=explode(" ",$string);
for($i=0;$i<$wordnum;$i++)
{
$re_string.= " ".$string_arr[$i];
}
$str= $re_string.$trail;
print $str;
}

Compiles fine here under 4.3.3. If it's giving errors at runtime, post
examples of data that cause them, and the errors themselves.

### check wordnum against actual number of words in string_arr
if ($wordnum > count($string_arr)) $wordnum = count($string_arr);

$re_string = '';
for($i=0;$i<$wordnum;$i++)

$str= $re_string.$trail;
print $str;

Thanks in advance

If you'd tell us what the errors are it might be easier to tell you why
they show up.

I imagine that $wordnum > count ($string_arr) for the set of parameters
you're passing to this function. You need to modify your routine to count up
to $wordnum only if count ($string_arr) >= $wordnum.
