[PHP] String Length ??
Hi there
I'm new to PHP (as some may know)...
ive spotted / Found the answers to 2-3 problems
tonight - By looking through the PHP documentation..
but this problem is perplexing..
Ok - Ive got a FORM - Which basically, I put lots of
text into it (For testing purposes, I go to news
websites copy entire articles).
The PHP script chops up the paragraphs - into one long
line of text (one line per paragraph..), its in an
array $text.
Ok - I loop through the array, all the text is how
it should be - displaying properly..
PROBLEM :-
Now - All I want to know - Is how long each line is -
(eg number of characters - Ive already removed
double-spaces its now single-spacing (if any)..)
EG - Is a line 34 characters long, 127, 945 ?
Ive looked through the PHP 'Functions' the PHP
'documentation' for length (couldnt find anything..
??)
Ive found this command :-
http://nz2.php.net/strlen
Which seems perfectly fine...
Ive got this code (without the === signs)
===
foreach ($text as $color) {
echo SAF '$color' - ;
echo B.strlen($color)./BBR\n;
}
===
the SAF is only for my reference - See it on the
screen..
QUESTION :-
Is this the right code to use ? to find the length of
each line ? ($color) - No worries - Ive just copied
code from the web..)
PROBLEM :-
It looks fine - EXCEPT when I see a 3-line paragraph -
the PHP code is telling me its over 1,200 characters
long..
(assuming 80 characters per line, 100 AT MAXIMUM) -
thats only 240 -300 characters...
If the paragraph were 1200 characters - That would
need 8-10 lines of text...
So - Im asking here (see above)... - If Ive got the
correct code / Command...
Thanks for the help...

[PHP] This Group....
Hi there Got PHP going :) - ok - Is this the correct group to ask ? Or can anyone suggest another group / forum for newbie how-to questions.. BASICALLY :- Ive been programming in HTML / CGI (Perl) for several years, have only 'briefly' done PHP.. - At work, Someone wants one of my CGI scripts to convert to PHP... Ive only discovered this forum a few hours ago - have for the last 2 days/nights been trying to figure out how to get PHP going / running (on my home server).. (its Sunday Morning here)... Anyways, Can someone point me in the right direction to some tutorials ( *EXAMPLES* ) to do the following functions (or point mer to an appropriate forum - see above).. :- Open a file insert into an array/variable. (im trying to figure that one out now - get file-open errors).. ( close / flock etc... - not sure if flocking is on PHP ?) :- turn a variable (split it) into an array.. :- Loop through an array - display a line IF it matches another variable etc.. I think those 3 things are good starting points - I think I'll learn fast - But just need pointers to the usage / PHP commands - That I know I can do in Perl.. Thanks G __ Do you Yahoo!? Yahoo!

[PHP] Re: cookie sharing between asp and php
Scott St. John [EMAIL PROTECTED] wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I have developed a security application for our intranet that handles a user login. It writes values to a cookie and uses that to verify them on the intranet sites until the sessions expire. Since we have not totally moved over to PHP I have some ASP applications I need to protect as well. Q1-I feel dump for asking this, but ASP can't read the PHP cookies, correct? My current solution might be to pass a variable from the php page to the asp page and have it write it's own set of cookies. As far as I know - ALL cookies set by a particular server - can be read re-set by any programme / process on the same server / website.. So your ASP script could read your PHP cookies vice-versa.. I'm just learning PHP, dont know cookies as yet (I use Perl/CGI for cookies) have no experience at all on ASP... I'll suggest to try a small PHP a small ASP page, try set/read the cookies.

[PHP] Sub groups ? - Programming structure...
Hello, - I'm used (in years gone by) to the Qbasic programme, where i can create 'sub' routines, view each routine on its own - Without reference / Viewing the other code.. (I think its good like that..).. I know in CGI/Perl - you can use sub-routines etc... 1) Does PHP allow sub-routines, eg - I can send values to the routine, it processes it does whatever it requires returns to the spot where I called it from. 2) For those of you that know Qbasic know what i mean, is/are there any programmes out there that can allow you to view / see any sub-routines in Perl and/or PHP one at a time, list them .. (I hope so) - Good, but not necessary.. G. (time for bed). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Ive been learning MySql for about 1 week now - joined a MySql
group - but some questions I ask are more PHP related not directly
involving MySQL..
anyway, for my big test script, Ive got the above URL
Just 'view source' to view the PHP scripting language...
when running, it searches your databases brings up a list of active
databases.
When selected, it brings up a list of tables within the database..
(those two functions are ok..)
Now - in the script, - near the top, it says :-
if ($action =='tables'){ (start of problem area..)
Now - when you select the table, it displays all the names of each
column, within the table. (that part works..)
it has :- $tot=$i; - $tot now holds the number of columns in that
table - For my example on my PC, it held the number '17' which is
correct.
it now has 2 'loops'...
a) for ($count = 1; $row = mysql_fetch_row ($query_result_handle);
++$count)
b) for ($counta = 1; $tot; ++$counta)
Loop a, loops through the 4 rows of the database.
Loop B, displays all (17) of the colmns for each row...
Now - Problems
1) When my script runs, it is VERY fast - Doing things normally.
- EXCEPT - when it comes to the 2 loops.. - it goes Very slow - I
realise its got to do 2 sets of loops - but its going at a much
slower rate than if i did the same loops, on another programming
language.
2) It only displays the 1st row of my data.. - For the example
database i tested, I knew it had 4 rows.
problem questions :-
a) Is my looping correct - Or can anyone find a loop-hole / problem
in my programming. (Im not telling you if the pun was intentional or
not.)
PS - Ive now realised something, changed my line from :-
for ($counta = 1; $tot; ++$counta)
to
for ($counta = 1; $row = mysql_fetch_row ($query_result_handle);
++$counta)
- now my script is really fast - However it doesnt show much of the
1st line of data :-(
PS, the uploaded one (URL above) - doesnt show the change - as yet..
Can anyone advise what im doing wrong ?

Re: [PHP] Phone number validation

Then do validation on those numbers..
