Where does one go to get this kind of help? Thanks, John DROP TABLE IF EXISTS `data`; CREATE TABLE `data` ( `id` int(5) NOT NULL auto_increment, `name` varchar(255) NOT NULL, `email` varchar(255) NOT NULL default '', PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ; INSERT INTO `data` VALUES(1, 'Allen, Carolyn', '[EMAIL PROTECTED]'); INSERT INTO `data` VALUES(2, 'Atwood, Margaret', '[EMAIL PROTECTED]'); DROP TABLE IF EXISTS `shopping`; CREATE TABLE `shopping` ( `id` int(5) NOT NULL auto_increment, `name` varchar(100) NOT NULL, `address` varchar(100) NOT NULL, `email` varchar(100) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=0 ; I'm not certain but think you need to include a 'references table_name(field_name)' clause that sets up the Foreign key relationship between the 2 tables. I think the Reference clause would replace the auto_increment in your primary key of the referencing table. The references goes into the secondary table, not the main one and it definitely doesn't replace the auto_increment field. You end up with something like this: create table person ( person_id int primary key, name varchar(255), email varchar(255) ) engine=innodb; create table shopping ( shopping_id int primary key, person_id int, foreign key (person_id) references person(person_id) ) engine=innodb; insert into person(person_id,name,email) values(1,'Name','[EMAIL PROTECTED]'); insert into shopping(shopping_id, person_id) values(1, 1); The 'person' table still needs at least a unique field for the field being referenced (the foreign key), usually a primary key (and if necessary an auto_increment). The secondary table uses that key to check: - if that id exists: insert into shopping(shopping_id, person_id) values (2,2); ERROR 1452 (23000): Cannot add or update a child row: a foreign key constraint fails - if it should delete that id (when using on delete cascade) mysql delete from person where person_id=1; Query OK, 1 row affected (0.00 sec) mysql select * from shopping; Empty set (0.00 sec) - if it needs to be updated (when using on update cascade) mysql update person set person_id=2 where person_id=1; Query OK, 1 row affected (0.01 sec) Rows matched: 1 Changed: 1 Warnings: 0 mysql select * from shopping; +-+---+ | shopping_id | person_id | +-+---+ | 1 | 2 | +-+---+ 1 row in set (0.00 sec) See manual for more examples: http://dev.mysql.com/doc/refman/4.1/en/innodb-foreign-key-constraints.html -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks for getting me started. (Sorry, I'm a top quoter.) Below is some
working code for the archives.
What I've learned so far is that :
1) what I'm referring to in `person` has to be a key.
It should be a unique item rather than just a 'key' (indexed item).
If you add this data:
insert into person(name, email) values ('my name', '[EMAIL PROTECTED]');
insert into person(name, email) values ('another name',
'[EMAIL PROTECTED]');
and I share an email address, and you use email as the foreign key,
which one is it going to link to?
Mysql should really throw an error if you try to reference a non-unique
field or combination of fields - every other db does.
A unique key can cover more than one field:
create table person
(
person_id int primary key,
name varchar(255),
email varchar(255),
unique key (name, email)
) engine=innodb;
So you can only have one combination of name email then you can use
that as a foreign key:
create table shopping
(
shopping_id int primary key,
person_name varchar(255),
person_email varchar(255),
foreign key (person_name, person_email) references person(name,email)
) engine=innodb;
Though I'd suggest starting off with the person_id (primary key) as the
foreign key so you don't have data redundancy and integrity issues
(unless you use on update cascade).
I'd also suggest getting an intro-to-sql book as this is all reasonably
basic stuff.

Re: [PHP] how to possibly cache something and the theory of better performance / better speed
I used to use a script to grab a random image from a folder of images by
scanning the folder, returning the list of images, getting one of them
randomly and displaying it.
Isn't that what the code is doing? Maybe I'm missing something but
you've only mentioned one method.
What's the second method to compare against?
OK now, getting greedy I want to take it to another level. Instead of
having to read the folder for images every time, why not read the image
names into a file so that we can maintain therbey caching the list. This is
based on 25-30 images in the folder you might even have more. Since in this
case we're not going to add images too often, then we can upload the images
delete the cache list and a new one will be generated hopefully saving time
for all future executions.
Assuming only 25-30 images am I splitting hairs here?
Yes. I don't think you'll notice any difference with this number, though
a quick script would tell you for certain.
$orig_image = 'logo.jpg';
$cache_folder = '/path/to/folder';
for ($i = 0; $i 500; $i++) {
copy($cache_folder.'/'.$orig_image, $cache_folder . '/' . $i . '.jpg');
}
Of course if I have 200 pictures, then this is the way to go but would this
really make a difference?
Once you get a lot of images (500? 1000? more?) it will but if you only
expect 30 there's not much point.
Using a cache file you'll need extra checks (make sure nobody slips in a
symlink to /etc/passwd or a url or something) - but you should be doing
those checks anyway.

1) You don't need quotes around your field names.
2) You do need quotes around your data, plus you should use
mysql_real_escape_string to stop sql injection attacks:
$phone = mysql_real_escape_string($_POST['phone']);
3) What error do you get once you fix both of those up?
Your query should end up looking like:
$query = UPDATE phones SET last_name=' .
mysql_real_escape_string($_POST['last_name']) . ', ...
or
$last_name = mysql_real_escape_string($_POST['last_name']);
$first_name = mysql_real_escape_string($_POST['first_name']);
// set a default of NULL
$suffix = NULL;
if (!empty($_POST['suffix'])) {
// note - you need to add the quotes around the data here
$suffix = ' . mysql_real_escape_string($_POST['suffix']) . ';

Here's my question... I have a program, where I want to take out the
field names in a database table and display them... In other words
instead of writing:
$Query =SELECT First, Last, Middle, Add1 FROM mytable order by $order;
I want to write something more like:
$Query =SELECT $FIELDNAMES FROM mytable order by $order;
So I need to know how to get the field names from the database so that I
can populate $FIELDNAMES. I played a little bit and it looks like I
might be able to get what I want by doing 2 queries...
$QueryFieldNames = DESCRIBE $table;
And then some sort of a foreach or maybe a while to populate
$FIELDNAMES? Maybe an array so I could do $FIELDNAMES['First'] if I
needed to later.
then I can use my SELECT $FIELDNAMES FROM $table order by $order query
to do my query...
If $FIELDNAMES contains all the fields, I have to ask why?
If you just want them for the header or something you could do something
like this:
$fields = array();
$query = select * from $table order by $order;
$result = mysql_query($query);
$row_counter = 0;
while ($row = mysql_fetch_assoc($result)) {
if ($row_counter == 0) {
$fields = array_keys($row);
}
print_r($row);
}
Haven't actually tested it but saves another round trip to the db.

In this example you can just use a single query:
$query = insert into run(command, event_id, created, user_id, runtime)
select 'topic_change', registrationID, NOW(), .(int).$userid, NOW()
FROM registration WHERE event_id='.(int)$id.';

Are you using mysql_pconnect or just mysql_connect? Persistent connections do what you outline and keep the connection sitting there.

How do people generally structure their code to minimize the time they keep mysql connections open? Currently all db connections go through one file, which gets included at the top of the file.

Re: [PHP] Best practices for using MySQL index
Index on most integer fields only. Text fields can be indexed, but is not important when you design your DB well. Don't index just all integer fields. Keep track of the cardinality of a column. If you expect a field to have 100.000 records, but with only 500 distinct values it has no use to put an index on that column. A full record search is quicker. Hmmm... That's new. :) To explain that further the idea is that if you have something like a 'status' field which can only hold 5 values, there's no point indexing it if there's a reasonably even spread. If you could only ever have a handful of fields with a status code of '1', then it's worth indexing if you have to find those particular records quickly. I don't think mysql supports partial indexes, but some databases do so you only index the fields that match a certain criteria. I'd suggest a more thorough approach to working out what to index rather than just trying to guess what's going on. Work out how long queries are taking (either use the mysql slow log or if you're using a database abstraction class, it should be easy enough to hack in) and concentrate on those first. http://www.designmagick.com/article/16/PostgreSQL/How-to-index-a-database (While it's on a postgresql site, there's nothing specifically for postgresql in that article - the same rules apply to mysql, oracle, mssql). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The idea behind database normalization is you only ever have one copy of the data, you don't have to update multiple tables to reflect a change. So you only store the image in the 'images' table: create table images ( image_id int auto_increment primary key, image_name text, .. ); For multiple categories to share a particular image, there needs to be a link between a category and an image. If you only ever want one image per category, you could put the image_id in the categories table: create table categories ( category_id int auto_increment primary key, category_name text, image_id int, . ); However the problem with that is if you want more than one image, instead of adding another field to the categories table: create table categories ( category_id int auto_increment primary key, category_name text, image_id int, image_id_two int, . ); which means if you want a category to have 3 images, you need another field and so on, so instead you create a separate table: create table category_images ( category_id int, image_id int ); which means you could have 10 images for that category and no db changes are necessary. So you create the image as normal (insert into images ...). Then when you link it to a particular category, you insert into the separate table: insert into category_images (category_id, image_id) values (.); This also means if you update the image (eg change the name or alt-value or whatever), it's automatically reflected for all categories. How do you get an image for the particular category?

Re: [PHP] creating an xls file from mysql data
This is what the $_POST['selectedcontactlist'] looks like
121,17,97,123,243,52,138,114,172,170,64,49,60,256,176,244,201,42,95,4,
First question is why do you need to pass it through like that?
it is not coming across as an array so the foreach is throwing an error
I assume it always has a ',' in it if you only choose one box.
if (strpos($_POST['selectedcontactlist'], ',') === false) {
// no boxes were selected - or at least there is no comma.
die();
}
// turn it into an array
$selected_contact_lists = explode(',', $_POST['selectedcontactlist']);
This number are selected in a checkbox and passed with a javascript to
the script should I be converting them to an array in the javascript.
No need to do that either, just make the form variable an array:
input type=checkbox name=selectedcontactlist[] value=X
The [] turns it into an array which php can then process automatically
as an array.
You can check that some checkboxes are ticked using an idea similar to this:
http://homepage.ntlworld.com/kayseycarvey/jss3p8.html
Though I'd just either set a flag or counter instead of a message when
you find one that is checked.
If you're just checking that any are checked, as soon as you find one,
return true out of the function.

Re: [PHP] tracking Mials Which were bounced.
mike wrote: Seems like the general way is to create a mailbox (POP3 or IMAP) to accept the bounces, then check it periodically and mark the emails as invalid in your local database. I would set threshholds so you don't mark something failed that only bounced once - it could have been a mail setup error or something else; I'd say wait for 3 failures in a 7 day period at least. If you get 3 bounces by that point, the address is probably safely dead. You can use PHP's IMAP functions to check the mailbox (even for POP3) or a million classes or your own functions directly on the socket (POP3 is a simple protocol) - it also helps if you parse the bounced email message to process the return address and the mail code; perhaps build something better than just 3 failures = invalid, but actually determine if they're full out failures, or if they're just temporary bounces, etc. I use this method and it works reasonably well. The hard part is the last sentence - there are so many ways to say mailbox full - half don't include smtp error codes, the rest tell you the same thing in thousands of different ways. -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] PHP + MySQL transactions
Philip Thompson wrote:
Hi all.
I'm currently working on a project that's in its beta stage. Due to time
restraints, we were unable to build in transactions from the beginning.
Well, we're getting to the point where we can now put in transactions.
Basically, I'm curious to find out your opinion on the best way to
accomplish this.
Currently, my thoughts for doing this are:
?php
function someFunctionThatNeedsTransactions ()
{
$this-db-begin(); // Start transaction
$this-db-query(SELECT...); // Run my queries here
$this-db-query(UPDATE...);
// Do some PHP logic here
$this-db-query(SELECT...); // Run more queries
$this-db-query(INSERT...);
$this-db-commit(); // Commit transaction
}
?
If there was a failure in one of the queries, that would be caught in
the database class ('db' instance) and ?php $this-rollback(); ? would
be called. Note that all the tables are InnoDB and the above
code/functionality works.
Ideally, I would have liked to use stored procedures, but that decision
was not mine. So are there any complications I'm potentially missing?
I'd get your db class to handle nested transactions, so if you had
something like this:
$db-begin();
someFunctionThatNeedsTransactions();
...
.. oops, need to rollback.
$db-rollback();
the bits between someFunction and the rollback will be committed (by
the function) and can't be rolled back.
See http://dev.mysql.com/doc/refman/5.0/en/savepoints.html
The situation might not come up but it can't hurt to have it already
built in just in case.

Re: [PHP] PHP + MySQL transactions
See http://dev.mysql.com/doc/refman/5.0/en/savepoints.html The situation might not come up but it can't hurt to have it already built in just in case. This doesn't appear deal with *nested transactions.* It appears that it will use a single transaction and you can just save up to a certain point upon failure. As of this point, it's all or nothing b/c we are dealing with fairly crucial information. However, I will look into building savepoints into the class so that I'll have that option in the future. Sounds like a difference in semantics :P In my head they're the same thing - if the middle bit fails, it'll roll back. If it works, you continue doing whatever you're doing. If everything succeeds then you commit everything at once. If part of something fails, then you roll it all back.

You're running the wrong query.
You're building a query in $update_sql but running something else.
Change the mysql_query($sql_1) line and you should be right to go.
Slightly OT, any better way to run the multiple updates needed above than
instead of running the update query in a loop?
I searched google and the best i could find was the IN() for mySql... but
that does not take 2 parameters (eg: cardno and rand_str) it would work just
on card_no like this in('14','34')
An IN() clause is the same as:
field='x' or field='y'
so you can use that:
update greetings set is_sent=1 where cardno='a' or cardno='b'
if you need the extra stuff (about the rand_str) you should be able to:
update greetings set is_sent=1 where (cardno='a' and rand_str='a') or
(cardno='b' and rand_str='b')
Try it with some test data first obviously.

Re: [PHP] A problem with fgets()
Usamah M. Ali wrote:
Hello,
I have a function that picks up a random entry from a file consisting
of city names, each name on a separate line. The random value is
generated by rand() before fseek()ing to the position determined by
it. The problem is that when using fgets() to get a random line, it
returns a part of the city name, not the whole name. AFAIK, fgets()
reads a whole line, and even if it's in the middle of a line, it reads
the whole next line.
fseek doesn't go to the start of a line, it goes to a particular byte -
so that's where the problem lies (not with fgets). There's no function
(that I could see) which would go to the start of the line based on that
offset (I guess you could fseek to a particular spot then reverse char
by char until you find a newline - but that'll be rather slow for
anything that has a long line).
You could read the whole thing into an array and do a rand on that:
$cities = file('filename.txt');
// take 1 off from the max number as $cities is a 0 based array
$number_of_cities = sizeof($cities) - 1;
$city_number = rand(0, $number_of_cities);
$city = $cities[$city_number];
Though if you have a big file that reads the whole thing into memory etc.

Re: [PHP] A problem with fgets()
I just need to figure out why when using fgets() with fseek() rand(), the script returns partial strings form the city names. Because fseek doesn't necessarily put you at the start of a line. It puts you anywhere (which could be the start, middle, 3 chars from the end) according to the number of bytes you tell it to start at. Then fgets reads the rest of the line. A file that looks like this: (numbers are the bytes for ease of explanation) 123456789 is going to be different to a file that looks like this: 1234 56 789 and if you tell me you want to start at byte 5, then in file 1, that's the middle - in file 2 that's the start of the second line (#4 is a newline char :P). -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Did you reconfigure php? What configure command (and arguments) did you use? Did you get any errors when you ran configure or make? Normally when you try to build a module like this you need the -dev or -devel or -headers package (ie imagemagick-dev or -devel or -headers depending on how they decided to name it).

Re: [PHP] PHP Runs But Does Not Display on Linux
Wei, Alice J. wrote:
Hi,
I am currently using a Linux box with Fedora to run my PHP scripts, which I
have seen in the download page at http://www.php.net/downloads.php that
We do not distribute UNIX/Linux binaries. Most Linux distributions come
with PHP these days.
What I am wondering is, if I can run my scripts by using the command like
php some_php.php, as long as it does not require me to have it displayed on
the web page or in need of using a mssql_connect function, it does not give
me any errors at all. Otherwise, it consistently gives me errors Call to
undefined function: mysql_connect()
I can only see the HTML code of the php functions I call within the code at
the command output in text format, but I cannot see it on the browser.
Are these two errors related? I tried installing PHP and Apache afterwards,
but it seems that it is not providing a different message. Have I missed
something here?
Some servers have display_errors disabled in their php.ini files and it
only logs errors.
If you add:
error_reporting(E_ALL);
ini_set('display_errors', true);
to the top of your test script, does it show any errors now?
mssql is not a standard module, you'll need to get your host/server
admin to install it.
There are detailed instructions on the php site:
http://www.php.net/manual/en/mssql.setup.php
If you get stuck, at which step do you get stuck?

Re: [PHP] unlink oddity

Why not just unlink($path) ? It's the same thing but you take 2
variables out of the problem.
While you're trying to debug this remove the '@' signs. An error message
will be particularly useful.
Check your logs if you can, otherwise turn up error reporting and
display errors until you work out what's going on.
error_reporting(E_ALL);
ini_set('display_errors', true);

No, #5 is the port number (http://www.php.net/mysqli_connect).

Re: [PHP] losing mysql connection during cron job
Thanks for the suggestion. I am currently successfully working around this error by another method, although your suggestion is probably better. The reason I posted this problem, though, is that I want to understand *why* I'm getting the Lost connection to MySQL server during query error. If anyone has had a similar experience using cron jobs or sleep() I'd love to hear from you. - database is restarted for whatever reason (log rotation, dba does an upgrade etc etc). - mysql has a 'wait_timeout' setting which could trigger it http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#option_mysqld_wait_timeout You need to do a mysql_close(); mysql_connect(...) before mysql_query works again - otherwise mysql_connect will just return the same resource id (or I guess just use the 'new_connection' flag for mysql_connect and skip the mysql_close()). -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Hi all:
We are use PHP PDO's Prepared statement to send SQL query to Mysql server.
According to PHP PDO doc, Prepared statement are fast for executing multiple
SQL queries with same parameters. by using prepared statement you avoid
repeating the analyze/compile/optimize cycle
Our application is a web application, each request will have a new Prepared
statement handler generated by PDO Lib. so prepared statement actually
slower than non-prepared statement.
I just want to know how can we cache Prepared statement handler, So we can
re use it in later http request.
for example:
we have a query to pull out all product information from mysql db, each
query just has a different product id , all other parts are same.
The query is the same.
It works out to be:
select * from products where id='X';
So you can just do something like this:
$product_query = $dbh-prepare('SELECT * from products where id=?');
$ids = array(1,2,3,4,5);
foreach ($ids as $product_id) {
$product_query-execute(array($product_id));
$product_details = $product_query-FetchAll();
print_r($product_details);

}else{
$Tchecked1 = NULL;
$Tchecked2 = CHECKED;

$tab = $_POST['rdoTab'];
$record = $_POST['txtRecord'];
$updateQuery = UPDATE `current` SET Tab='$tab' WHERE

Checkboxes and radio buttons only post back the values for the ones

If you have:
form method=post action=?php echo $_SERVER['PHP_SELF']; ?
input type=checkbox name=ids[] value=1Option 1br/
input type=checkbox name=ids[] value=2Option 2br/
input type=checkbox name=ids[] value=3Option 3br/
/form
view that, and tick options 1 and 3, only they will be available in $_POST.

- and it will be exactly the same in perl, python, ruby and any other
language.

I was hoping there's a way to tell apache to block requests where
id=non_numeric.
It's trying to do a remote inclusion.
It's easy for you to fix in php:
if (isset($_GET['id'])) {
if (!is_numeric($_GET['id'])) {
die(Die hacker die!);
}
}
I'm sure there would be a way to do it with ModRewrite or something but
it's 5 lines of code in php so I'd do it there *shrug*.

Re: [PHP] PHP4 vs PHP5 classes
I have run through the script with a debugger, and sure enough, we only enter function Players once. Is this normal behaviour for PHP5 vs PHP4? Is there a way for me to force $this-max to be calculated each time function max is called? Since the Players method is a constructor, it's more about how you set the object(s) up.

Well see here is where it gets messy! This is not my code - I've ported a phpnuke module over to dragonflycms. The $players object is created before the loop: $players = new Players($lid); snip Which means the code is only executed once since it's in the constructor. It's not changing per loop because you're not calling the code.

Thanks Chris, I will give that a shot. Just to confirm, this script works just fine in php4, so do we put that down to pure luck, or has there been a change in php5 that will be causing it?

Re: [PHP] PHP4 vs PHP5 classes
Don't forget that in PHP5, the constructor named has changed. In PHP4 it called a method with the same name as the class. But, in PHP5, it looks for __construct() instead. If __construct doesn't exist then it falls back to the php4 way - makes it backwards compatible :) -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] limiting the amount of emails sent at a time in a batch send
I've done something very similar. I have a delivery timestamp column in the table that is initially NULL, and I set it to UTC_TIMESTAMP() for each row as I send the message. My query looks like this then: SELECT * FROM mail_queue WHERE delivery_timestamp IS NULL LIMIT 100. Andrew Then what do you do to get the next 100 emails without sending the same ones Re-read the reply. After each email is sent, the timestamp is set.

Re: [PHP] Why PHP4?
Per Jessen wrote: Lester Caine wrote: Some ISP's are still only supporting rather ancient versions of PHP4. They should simply be warned of the security risks. Some ISP's have a PHP5 offering, but again an older version simply because it causes less problems when converting from PHP4. The problem for an ISP is - with thousands of customers, he has no way of knowing who has used what PHP extension or feature. Without virtually guaranteed backwards compatibility, a mass upgrade of 4 to 5 could be a major headache. Besides, are the security risks sufficiently severe for the ISP to warrant the upgrade effort+headache? Definitely. I've been the server-admin behind this sort of stuff (actually php3 - php4 :P) and it's very hard to do even on your own servers. Clients get other developers to write their software so you have no idea what it does etc, you can't support it, you certainly don't want to break it - so as much as possible you leave the server alone (of course you upgrade for security issues, that's a given).

Grab all of the addresses at once and let SwiftMailer deal with the throttling: Of course there is. 1) What if the server gets rebooted in the middle of the send or the database goes down in the middle? You send to everyone again. 2) What if the host has a limit on how long a script can run for? You send to everyone again and again and again each time the script tries to start. 3) What if safe-mode is enabled on the server? You have a limited send time and possibly end up with the same outcome as #2. 4) What if you are sending to 100,000 email addresses?

Re: [PHP] Kill Magic Quotes
public static function restoreSlashes($string)
{
// Check if Magic Quotes is turned on.
if (get_magic_quotes_gpc())
{
// Add escape slashes.
return addslashes($string);
}
// Return a string that has escape slashes.

Wrong way around.
If gpc is enabled, then there are already slashes - no need to add them
again.
If it's not, you need to addslashes.
if (get_magic_quotes_gpc()) {
return $string;
}
return addslashes($string);
Though I'm curious why you need to re-add them at all.

Re: [PHP] newbie Q: How to say, if the fileNAME is equal to..., or better yet, if the fileNAME ends with '.jpg'?
But two of those entries are apparently named . and ...
Right. That's linux doing that, not php. If you jump into a ssh
connection and do an
$ ls -la
you will see
. and .. at the top.
if ($filename == '.' || $filename == '..') {
continue;
}
I haven't yet found the 'string.ends_with'
function in the docs, so I am just seeing if I can (to learn step by
step) instead wrap that echo line with an if statement that says if
the name of the file is equal to (.jpg), like so:
$ThisDir = getcwd()./thumbs;
$DirHandle = opendir($ThisDir);
if ($DirHandle = opendir($ThisDir)) {
echo Directory handle: $DirHandle\n;
echo Files:br /hr width=\25\%\ align=\left\ /;
while ((false !== ($file = readdir($DirHandle))) 1) {
if (true == ($file=.jpg)) {
echo $filebr /;
}
}
closedir($DirHandle);
}
But instead of printing only the name of the file which is equal to
.jpg, it seems to actually set the value of $file to .jpg on
each iteration of the while loop, so what I get is a list of files all
having the same name (.jpg) and their number is equal to the
actual number of files in that dir (plus 2 - for the . and .. files).
Because you have:
$file = 'xxx.jpg';
That is an assignment.
What you want is a comparison:
$file == 'xxx.jpg';
Note the double ='s.
http://www.php.net/manual/en/language.operators.php
In this case, I'd use the pathinfo function to break up the file/path:
