Hi Jan,
thanks for you reply! I have tried the snapshot
(for Windows) that you pointed me to. The program
works as you say - which IMHO is a bug.
The output is - as you mention:
1<BR>
substr("A",0,1):1<BR>
substr("A",0,0):1<BR>
substr("A",1,1):<BR>
substr("A",1,0):<BR>
This means that substr("A",1,1) and substr("A",1,0) are both
not strings. Therefore substr does _not_ always return a string.
If this is considered correct, then it should be mentioned in
the documentation.
Personally, I would prefer this to be considered
incorrect: I would prefer substr($s,$n,$m) to always return a string,
at least if $s is a string and $n and $m are integers.
Please either improve the documentation or make substr($s,$n,$m)
always return a string (at least if $s is a string and $n and $m are
integers).
Thanks for putting this PHP together. It is a great means to produce
results quickly!
Cheers,
Raimund

substr($s,$n,$m) is supposed to always return a string (at least if $s
is a string and $n and $m are integers).
However:
is_string(substr($s,strlen($s),$m))
returns false, so substr did not return a string.
Example:
echo is_string("")."<BR>\n";
echo "substr(\"A\",0,1):".is_string(substr("A",0,1))."<BR>\n";
echo "substr(\"A\",0,0):".is_string(substr("A",0,0))."<BR>\n";
echo "substr(\"A\",1,1):".is_string(substr("A",1,1))."<BR>\n";
echo "substr(\"A\",1,0):".is_string(substr("A",1,0))."<BR>\n";
