Always do server side validation, and if you have the skills, time, or are being paid then add javascript validation to make the user experience better. I have a general contact form which checks the input server side (PHP) and if there's something wrong then it indicates as such, and shows the user their input, with the errors and why (e.g not a valid email address, etc..). If it was for anything larger than about 10 fields per page, then javascript validation can be useful. Slightly off topic, but does anyone know of an easy way of checking user input like the PHP filter_var() function? I've seen plenty of libraries for AJAX, and the like (Prototype, jquery, etc), but haven't run across any for standard form input validation. Thanks.

The system that sent it in this case is the html output; so you need a method of displaying errors in the html. That is the bare minimum and always needed. As for making the experience nicer; javascript is good for this; it can be used to pre-validate input on the way in to the system; but should not be relied upon as it can be turned off, stop functioning due to another faulty javascript on the page or simply not be supported by the client. You still need the server side validation though. So.. more of a case of always validate server side; and should / do you want to use javascript validation in addition. IMHO :p I put a small one together using regular expressions, http://www.ashleysheridan.co.uk/coding_php_validation.php I tend to use it for all my projects where I need to validate the user input. It uses a whitelist-style approach rather than a blacklist style (i.e. it has an allowable entry format rather than checking to see if certain characters don't exist in it) which has had the added benefit of preventing an SQL injection attack that I've seen as well.

[PHP] array_reverse() and garbage collection
Hi,] So I've been thinking, because occassionally I do, about array_reverse() and how to implement it. Of course, it's entirely theoretical, because it would a total waste of time. But I'm wondering which of two methods would be best. 1. Do it correctly and in place. ie, loop through the the first half of the array once swapping element 0 with the end one, element 1 with the next to last one and so on. 2. Loop thru the array once creating a new one. Normally this would take up a little more memory because you end up with two copies of the array in memory just before the end of the function. But what if you set the original element to null once you've assigned it to the new array? The most memory I can see it using is two copies of one element. But only if garbage collection kicks in before you start on the next element. Does garbage collection kick in that often? From what I remember from an article by Derick Rethans, if the refcount is zero, then it gets cleaned up.

Re: [PHP] array_reverse() and garbage collection
What about using array_pop to take the bottom array element from the first one and add it to the second? So basically you are feeding the 2nd array from the bottom of the 1st one, and assuming garbage collection is done for each call of array_pop, then you'd only need the memory usage of one copy of the array, not two. The downside is that it's not going to be as fast as just looping through, and making two copies, but the upside is less memory usage. I can see it being particularly useful for processing large arrays on memory restricted webservers which would possibly not have the ram for two copies of the array in memory at the same time. Not sure if that actually helps, seeing as array_reverse() is already a function that's probably written in C which could just make a copy with re-arrange the pointers or something.

Make a format and use it with CURL. Thats it. So Simple. You never gonna need to know who is generating the site, PHP or ASP.NET. I downloaded Wireshark onto Windows XP, got as far as Capture Options from Ethernet, Capture Filter is host IP address of target page, click Start, go to browser and access page, Stop Wireshark, Save captured file or Export as HTTP object which gives me the source of the page again. Is this what you mean? What do you mean by make a format - do you mean for instance parse the page with string finder functions etc. How is this helping over identifying the correct POST variables (using LiveHTTP etc) of the request and feeding into a curl function? What do you mean by 'make a format' versus 'pattern changes over time' - is format a Wireshark function, if so where do I find it. Thanks, John make a format is not like a button in wireshirk that has label make a format and it will do everything for you. You have to do it yourself. By wireshirk you'll see every type of headers and contents for almost every type of protocols. So you'll use this soft for analyzing the http conversation. Data will not only be in content but also in headers. so parse both if needed. then use the same data and make successive requests. If you are using regular expression it will fail to match if pattern changes. Your pattern '/input type=hidden name=__VIEWSTATE id=__VIEWSTATE value=([^]*?) \// will match input type=hidden name=__VIEWSTATE id=__VIEWSTATE value=ABC7D5ACSE / but wont match input type=hidden name=__VIEWSTATE id=__VIEWSTATE value=ABC7D5ACSE. Do you see the difference?? It wont mach input type=hidden id=__VIEWSTATE name=__VIEWSTATE value=ABC7D5ACSE / too. Because the attributes order is changed. Your regex will not work but their website will render very well. to overcome this, you have to use html/xml parser. So you can go to input element. then look for name attribute and if the name attribute is __VIEWSTATE then fetch the value attributes content. To make any input element name, value attribute must be present. So your code will match every time. It wont fail in 99.99% case.

Re: [PHP] A MySQL Question
I believe I've seen EXIST used when creating backups of tables to test for the existence of a table and DROP it if it exists (if you select the option to add such code in phpMyAdmin). So that would have been my answer (give or take more specific wording for an interview). As for pronounciation... I used to say S-Q-L for all such references and still use it when talking about the language most of the time, but some of my coworkers sequel has rubbed off on me, especially with MySQL. I used to cringe heartily at such wordification of acronyms that didn't actually spell a word, or something similar that at least contained some vowels, but it's kind of nice to reduce a mouthful a little bit. I've never heard squell, though.

I distinctly remember Paul Hoffman, the director of the Internet Mail Consortium (http://www.imc.org/) saying that the left side of the @ has always been open to whatever characters you want to use. I was attending the IDNS WG as they created PUNYCODE when he made that statement. Now maybe you can use anything you want, but it doesn't mean that it will be translated correctly. The same really goes for the same on the right hand side of the @, but some people have difficulties distinguishing between the _actual_ email address and it may be rendered when the domain part is converted from punycode. The actual email address might be [EMAIL PROTECTED] That's correct. The xn-- is the prefix for PUNYCODE. Previous algorithms (AMC, RACE, etc.) used other prefixes. After all is said and done, these were just ways to use 7 bit characters (unfortunately, the default for the Internet) to assemble/represent 8 bit characters.

I've certainly never used them, but I can imagine information_schema

-- is that it?
Cheers,
tedd
not many have :p but there's so much more power and speed can be opened
up by using them.. to get you started ( I highly recommend this )
try:
SELECT * FROM `information_schema`.`TABLES`;
then:
SELECT * FROM `information_schema`.`COLUMNS`
then cunning way's to combine the two.. for instance you could query
these two tables to return back a list of all columns in database X
which are of type text and use them to search you're entire database in
one go like:
select table_name, column_name from information_schema.columns WHERE
table_schema='DB_NAME' AND data_type IN ('char','varchar','text') AND
CHARACTER_MAXIMUM_LENGTH 3;select table_name, column_name from
information_schema.columns WHERE table_schema='DB_NAME' AND data_type IN
('char','varchar','text') AND CHARACTER_MAXIMUM_LENGTH 3;
replace DB_NAME for the database you want to search, you may want to
include type's like mediumtext etc..
point is, the information_schema tables reside in memory so are ultra
quick to query; and they are always up to date; and they give you far
more information than normally available.
so many options.. rows in a database (not table)
SELECT SUM(TABLE_ROWS) FROM `information_schema`.`TABLES` WHERE
TABLE_SCHEMA='DB_NAME';
etc etc..

Ash www.ashleysheridan.co.uk on that note, and seeing as it's sunday.. Three male programmers were in the bathroom standing at the urinals. The first programmer finishes, walks over to the sink to wash his hands. He then proceeds to dry his hands very carefully. He uses paper towel after paper towel and ensures that every single spot of water on his hands is dried. Turning to the other two, he says, At Microsoft, we are trained to be extremely thorough. The second programmer finishes his task at the urinal and he proceeds to wash his hands. He uses a single paper towel and makes sure that he dries his hands using every available portion of the paper towel. He turns and says, At Intel not only are we trained to be extremely thorough but we are also trained to be extremely efficient. The third programmer finished and walks straight for the door, shouting over his shoulder, At Sun, we don`t piss on our hands. As the Sun guy is shouting over his shoulder, an open-source developer stops beside him and pees on his leg... while saying, open source developers do it however we please.

In any event, the interviewer asked me how long I've been using MySQL and I replied several years. After which she asked a single question, which was What does EXIST mean? There is no 'Exist' keyword in sql, it's 'EXISTS'. Everyone seems to know the drop table if exists syntax but that's not the right one they are after (and it's non-standard sql). There is an 'Exists' keyword for subselects. Instead of doing an IN query, you can do an 'exists' query - but it's use is very different. It returns true if any row in the subquery exists or false if none exist. The idea is instead of: select * from accounts where company_id in (select company_id from companies where name='X'); you do select * from company where company_id exists (select company_id from companies where name='X'); the subselect checks the company table for the id, if it exists, the outer query runs. It does not matter what company_id is returned from the subquery, just that at least 1 does return. I've never used this anywhere myself because I usually care what id's are returned from the subquery.

I have a string that is: Jason Slack

I am looking at parse_str, but I dont get how to do it with a space. The

Then I want to assign like:

Any ideas?

Re: [PHP] A MySQL Question
EXIST? Yeah I certainly have seen it before in the result of a mysqldump, but from the top of my head, I probably wouldn't have known in exactly what context it is used. I've used MySQL for 5 years now and i think if you ask such a question, you don't know what you should be asking because the context of EXIST is hardly ever needed, and if, if you know where to look for it, that's more important than being able to reproduce it in from the top of your head. It's like asking: Do you know the syntax for ... where ... is a rarely used function in PHP or any other language. It's like requiring your employees to know every function of a language...

Re: [PHP] A MySQL Question
Right So, how are these different: SELECT * FROM t1 WHERE id EXISTS (SELECT id FROM t2) If there are *any* results for the subselect, the exists returns true. It's the equivalent of: select * from t1 where id is true; ie select * from t1; If there are no results for the subselect, the exists returns false, ie: select * from t1 where false; which will return nothing. to SELECT * FROM t1 WHERE id IN (SELECT id FROM t2) this returns specific id's that match. According to my understanding of the documentation, these would have the same result. No, they aren't. create table t1(id int, name varchar(5)); insert into t1(id, name) values (1, 'one'); insert into t1(id, name) values (2, 'two'); insert into t1(id, name) values (3, 'three'); insert into t1(id, name) values (4, 'four'); insert into t1(id, name) values (5, 'five'); create table t2(id int, other_name varchar(5)); insert into t2(id, other_name) values (1, 'one'); insert into t2(id, other_name) values (2, 'two'); this returns everything from t1: SELECT * FROM t1 WHERE EXISTS (SELECT id FROM t2); this returns 2 rows that match: SELECT * FROM t1 WHERE id IN (SELECT id FROM t2); -- Postgresql php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
