[PHP-DB] Re: PostgreSQL versus MySQL
On the contrary, MySQL is much better at handling table crashes and data corruption than PostgreSQL is. What you may have heard is that due to lack of transaction support, critical data may be lost "in transit" from your application to the database, in the event of a system crash or a dropped connection. Well, guess what? MySQL now supports transactions in its latest release. Using transactions is probably not really needed though, unless your data is critical, such as credit card numbers. As for a full comparison between the two, I think the bottom line is that MySQL is slightly more light-weight, but easier to use and faster than PostgreSQL. So if you're looking for a database for a relatively noncritical web application, I'd say go with MySQL, especially since that's what you already have experience with. One of the upcoming features in MySQL I'm really looking forward to is query caching, which is a great feature for web applications. Jon Valvatne Can someone outline the differences between the two? I am partial to MySQL from experience but want to get a good view of why one is better than the other. Also, I've heard that you will lose data with MySQL if a system failure should occur. Thanks.

Re: [PHP-DB] headers
Hi, you can't have ANY output whatsoever before adding a header. Even whitespaces before the opening ?php-tag are not possible. You also could turn "output_buffering" "ON" in your php.ini. But your ISP has to have them same setting and I don't know about disadvantages. So go with the first solution.

RE: [PHP-DB] headers
You need to put the headers before any output has been sent to the user, not
line on line 6, line 2 if possible. This includes spaces or blank lines
before the start of your php.
e.g. Here is script that creates a simple image:
?php
header ("Content-type: image/png");
$im = @ImageCreate (200, 200) or die ("Cannot Initialize new GD image
stream");
$background_color = ImageColorAllocate ($im, 00, 00, 00);
$text_color = ImageColorAllocate ($im, 233, 14, 91);
ImageString ($im, 90, 20, 20, "Hello", $text_color);
ImagePng ($im);
?
Regards,
Corin Rathbone
[EMAIL PROTECTED]
P.S. If you use the script you need the GD Image librays installed and
enabled.

Re: [PHP-DB] using LIMIT
On Fri, Apr 06, 2001 at 02:15:34PM +0300, Dainius Vaskelis wrote:
I suppose that you are using MySQL (because of LIMIT operator in SQL query)
I m using PostgreSql
So:
In the second query i write a query whereby i say
$result=pg_Exec($database,"SELECT mem_id,name from search LIMIT $count");
Now here i display the the first 10(say $count=10) records.
Now I know to display the other records i can say
$result=pg_Exec($database,"SELECT mem_id,name from search LIMIT
$count,$count");
but what condition to give to display pages of more than $count records
i.e how do i give for next existing page.
LIMIT operator has two parameters: amount of records of result, offset in
result.
So in order to paginate your output you need such scheme:
$count = 10;
$offset = 0;
loop begin
...
$result=pg_Exec($database,"SELECT mem_id,name from search LIMIT
$count,$offset");
$offset += $count;
...
loop end
What shall the loop be like,i mean the condition for terminating the search.
If you want to use this to make output as search engines do (output first 10
recs on the first page, and output links of other pages), so you need to
modify a litle bit. You need to pass by parameters page no, in other pages
link:
$count = 10;
$offset = 0
if is_set(page_no) {
$offset = $page_no * $count;
}
What is page_no here and doesn't $offset get overidden here
...
$result=pg_Exec($database,"SELECT mem_id,name from search LIMIT
$count,$offset");
...
Hope it'll help you. Good luck.
I was of great help but i want more help or URL or atleast a practical reference on
this.
Pls if possible look at the forms

What you need to do is to pass to the LIMIT clause the $first and $limit values where the $first is the number of the page of results you want to display times the number records you want to see per page which is also the $limit. Maybe you want to look at Metabase which is a PHP database abstraction page that lets you specify the range of rows that you want to retrieve pretty much like the LIMIT clause, except that it works well in all supported databases including PostgreSQL versions that did not support the LIMIT clause. http://phpclasses.UpperDesign.com/browse.html/package/20 With Metabase you may use this other PHP query result table display class that is able to display query result rows in HTML tables with optional links to go to the next, previous, first, last, etc... result pages.
