What about something like this:
$pos = (strpos(' ', $string, 76))?strpos(' ',$string, 76):strlen($string);

How would I write an IF statement that looks for the first space space (“ “)
left of the 76th character in a string or <br>, which ever comes first --- OR
the end of the string (IE the string is less than 76 characters long? I
specifically want is it’s character position in the string. Ron

... but you sound like you are looking for the 'wordwrap' function.

I am receiving this error:
Warning: strpos() [function.strpos]: Offset not contained in string
I have never seen it before, what do I do? I made one change to it though, you
didn’t have <br> in it before so I changed the syntax to:
$pos = (strpos(' ', $activity_description_result,
76))?strpos('<br>',$activity_description_result,
76):strlen($activity_description_result);

Shouldn't you check the length of the string before giving it the
offset?
From: a...@ashleysheridan.co.uk
$pos = (strpos(' ', $string, 76))?strpos(' ',$string,
76):strlen($string);
Doesn't strpos(' ',$string,76) look for the first space to the *right*
of position 76?
I really don't know how to do this except by exploding the string and
shooting the array of characters, keeping mind of the last space found
before you get to slot 75.

Hello List.
I have a sql command that counts, groups and sorts data from a table.
I need to insert the results of that sql command into different table.
My sql SELECT looks like this:
select count(*) as count, searchkeywords from searchtable group by
searchkeywords order by count desc;
and returns records like this:
578 green
254 blue
253 red
253 yellow
118 orange
.... etc.
My PHP looks like this so far:
$sql = "select count(*) as count, searchkeywords from searchtable
group by searchkeywords order by count desc";
$result = @mysql_query($sql,$connection) or die("Couldn't execute
checkcat query");
$num = mysql_num_rows($result);
echo $num;
The echo is of course returning the total number of records.... not
data as listed above.
I know a WHILE statement is to be used here, but can't get it to work.
How do I loop through the above found data, inserting each value as
like this:
insert into mytable (count, color) values ("578", "green");
insert into mytable (count, color) values ("254", "blue");
...etc
Thanks,
--Rick

Personally I'll get MySQL to do it for me using: insert into mytable (count,
color) select count(*) as count, searchkeywords from searchtable group by
searchkeywords order by count desc (see
http://dev.mysql.com/doc/refman/5.1/en/insert-select.html for more information
on INSERT ... SELECT)
Otherwise, you'll want to use mysql_fetch_assoc($result). Examples and
information can be found at http://php.net/mysql_fetch_assoc

Wow... I have never heard of the combination of INSERT... SELECT
before.... worked perfectly. Thanks.

I am writing a string parsing function.
I need to return 3 values from a function:
return $string_to_display;
return $string_to_parse;
return $continue_parsing;
I am not sure how to retrieve these variables.

I am writing a custom function and I need to be able to retrieve 3 values from
it.
string_parse_tool ( $string_to_parse )
The 3 variables I need to retrieve from the function are:
$string_to_parse
$string_to_display
$continue_parsing
I only know how to retrieve 1 variable from a function, not 3. Could someone
help me please?
Thank you.
Ron

2 options
Pass them back as an array
$data['parse'] = "some value";
$data['display'] = "some value";
$data['continue'] = "some value";
return $data;
or send it back as a delimited string
$data = $parse .'|'. $display .'|'. $continue;
return $data;

To return multiple values, you have to return an array:
return array($var1, $var2, $var3);
Then at the calling site, you retrieve them with a list construct:
list ($var1, $var2, $var3) = function_returning_array($param);

Beside the array() return you could ...
function string_parse_tool($string_source, &$string_to_parse,
&$string_to_display, &$continue_parsing) {
}
Now you can use ...
string_parse_tool($string_source, $string_to_parse,
$string_to_display, $continue_parsing);
Depending upon your code, you could drop the first parameter
completely, but that would always overwrite the supplied value with
the return value.
