explode,split,strtok etc...help!

Anon

I have a string "2,8,9,15,"

and want to split it at the "," to extract each integer

I'm using

$tmp1 = explode(",",$str);
echo("$tmp1[0], $tmp1[1], $tmp1[3]");

$tmp2 = split(",",$str);
echo("$tmp1[0], $tmp1[1], $tmp1[3]");

neither work,
is it because they are integers??
help!!!

It works for me with php 4.0.6.

Try putting a line like

echo count($tmp1);

to see how many elements there are, and if it's more than one, then try

echo implode(":",array_keys($tmp1));

to see what you get for keys and

echo implode(":",array_values($tmp1));

Check for types too.

nope, echo count($tmp1); gives me 1 ,
maybe cause they are integers?

the string is comming from the database

echo $row[slot]; //echos gives 2,8,9,15,
$str = $row[slot];

$tmp1 = explode(",",$str);
echo("$tmp1[0], $tmp1[1], $tmp1[3]");

$tmp2 = split(",",$str);
echo("$tmp1[0], $tmp1[1], $tmp1[3]");

im using php 4.04

ok, try this:

get $str from the database, and do this with it:

for ($i=0;$i<strlen($str);$i++){
print substr($str,$i,1).":".ord(substr($str,$i,1));
print "<BR>\n";
}

$t = ",";
print $t.":".ord(",")."<BR>\n";

You can use ord to see what ascii code a character is, and see if you are using the same comma as you think you are. If it's some off ascii code like 172 instead of 44, then that, or something similar could be the problem.

Thx Scott that was it (172)!!

speaking about wierd ascii listen to this story
this morning I find out that last night 550,000 update queries were done on my database. All my members profiles had been updated !!! total disaster !! It was a "freak" accident that I cant reproduce and dont understand what happend. this is the last query performed on the db

UPDATE profiles set
description = 'lalala'
update_time = 1007
WHERE profile_id = 'someone';

1007 is the begining of the current unix time...
now after 1007 there was a cents sign which I cant reproduce here. update_time is simply fetched from the time(); now I assume this cents sign made mysql ignore the WHERE clause in the query and updated all the records, freak accident ? what do you think?
