Well, you guys are awesome.
So the script below doesn't cause any errors (nice), however it
doesn't save the newly added child to the xml file (items.xml):
$xml = simplexml_load_file(items.xml);
$item = $xml-addChild('item');
$item-addChild('name', $name);
$item-addChild('desc', $desc);
$item-addChild('size', $size);
$item-addChild('price', $price);
I thought it would ? would i need to write using fwrite ?

You'll need to save your xml to the file once you are done manipulating it.
Use $xml-asXML('filename'); Check here:

As a matter of fact... For a while I was using a barcode generator to
test out inventory system before getting them professionally made. I
personally chose to go with Interleaved 2 of 5 as our barcode scanner
was able to read them accurately and it was the same format as our
campus ID cards. The trick with this is that it only supports numbers.
Code128 has three different encoding tables, table B which is most
commonly used, includes the characters 0-9, A-Z, a-z and a handful of
symbols which I don't remember of the top of my head.
I used a class someone else made which can be found here:
http://www.phpclasses.org/browse/package/2176.html
The code itself is quite ugly but as it was only needed temporarily it
worked. It might be a good starting point for you though.

and we scan the barcode. After scanning the barcode and verifying the user
data, we will proceed to decide whether his/her application is approved or
not.
I'm using fpdf to create the pdf file and for the barcode, I'm still looking
for suitable solution.
I don't know what type of barcode I should use for this purpose (I've
browsed internet and found out many types of barcodes..e.g 39, 93, ean-13,
c128, etc).
Has anyone used php and barcode generator with their application ??

The PHP_EOL is system dependent. If you want a solution that works on every
type of file you have to code it yourself. Here you have a function made
some time ago.
Maybe you can improve it.
If you want the result as a text format you can implode( PHP_EOL, $buffer )
Hope this helps you.
function explode($code)
{
$lines = array();
$buffer = '';
for($i=0, $len = strlen($code); $i$len; ++$i)
switch( $code{$i} )
{
case \r:
case \n:
if( $i+1 == $len )
break 2;
if( \r == ($next = $code{ $i+1 }) || \n == $next )
{
++$i;
}
$lines[] = $buffer;
$buffer = '';
break;
default:
$buffer .= $code{$i};
}
if( '' !== $buffer );
$lines[] = $buffer;
return $lines;

Re: [PHP] how to strip empty lines out of a txt using preg_replace()
The following snippet is untested and using Ash's regex (it is accurate
\s matches any white space). $content is what is getting stripped of the
new lines and $filtered is the cleansed output. See if that does the
trick for you.
$lines = str_split(PHP_EOL, $content);
$filtered = '';
foreach ($lines as $line) {
if (!preg_match('^\s*$', $line)) {
// Splitting on the PHP_EOL characters cause it to be removed be
sure to put it back
$filtered .= $line . PHP_EOL;
}
}

Re: [PHP] how to strip empty lines out of a txt using preg_replace()
and this is the PHP_EOL solution:

The PHP_EOL is system dependent. If you want a solution that works on
every
type of file you have to code it yourself. Here you have a function made
some time ago.
Maybe you can improve it.
If you want the result as a text format you can implode( PHP_EOL,
$buffer )
Hope this helps you.
function explode($code)
{
$lines = array();
$buffer = '';
for($i=0, $len = strlen($code); $i$len; ++$i)
switch( $code{$i} )
{
case \r:
case \n:
if( $i+1 == $len )
break 2;
if( \r == ($next = $code{ $i+1 }) || \n == $next )
{
++$i;
}
$lines[] = $buffer;
$buffer = '';
break;
default:
$buffer .= $code{$i};
}
if( '' !== $buffer );
$lines[] = $buffer;
return $lines;

The empty strings are forcing the parameter to be used as a string,
otherwise the line would be translated as something like this:
$dtd = preg_replace( /\n/, \n, $dtd);
Notice how that newline character is actually just the character by
itself, and is not a string.
Obviously, the exact end of line character will differ from system to
system, but this is a simple example of exactly why you had to
concatenate the PHP_EOL with those empty strings.

Is it possible in PHP to have the find be successful, even if the search criteria doesn't exactly match what's stored in the field? I think you don't follow the good path. A good way could be to have a strenger UI management. For exemple, here, you have an ID that is composed about 3 bits. So do the UI present three input fields, or write a smart input (with JS). Of course, in the control side (PHP), you have to check the format of the returned data. Here you can reject the input, or fall through some segment of code that try to interpret the submitted value. But in first time, do it simple and be rough to users.

[PHP] PHP inserting carriage returns into POST values?
Hey everyone. I ran into a really weird issue that I was hoping I could find some clarification on. In short, I have javascript functions that operate on hidden text values. Those values may be posted, in which case PHP then prints them back to the page via what comes in on $_POST. The weird thing is, I was no longer able to match substrings inside those hidden text values after posting via Javascript. I banged my head over this for a couple hours, until I realized that the string's length was being increased by one after posting (I found this out in javascript). Upon further investigation, I found that all instances of substring\n were being replaced by substring(carriage return)\n after post. For now, I'm simply doing str_replace(chr(13), , $_POST['value']) before re-inserting it into the HTML, but I was wondering why PHP is inserting those extra characters. Thanks!

PHP's include( file ) statement inserts the content of file here-and-now. You can even put the include statement within a for loop in order to include something multiple times... In that sense it is more like a /function/ and really different from cpp's #include /directive/. file can contain PHP code, which is evaluated as if it was here-and-now in the including PHP file; it can contain text/data, which is appended to the text/data stream being produced. All in all, to PHP the spot of file inclusion is not interesting, as long as the resulting PHP code and/or stream data is meaningful.

It's a web app that draws maps in a browser. Sometime it will generate a seg fault. The command should not take long, so if there is some script construct that will throw an exception after a few seconds if the command has not completed I could signal the user that the map will not draw and to reload the page.

[PHP] accessing variable from inside a class
Hi,
How do i access a variable from inside a class? ex. I want to use
$template_dir inside Template.
$template_dir = 'templates/';
class templateParser {
var $output;
function templateParser($templateFile='default_template.htm')
{
(file_exists($template_dir.$templateFile)) ?
$this-output=file_get_contents($template_dir.$templateFile)
:
die('Error:Template file
'.$template_dir.$templateFile.' not found');
}
}
I run Fedora 10, apache 2.2.11 and php 5.2.9.
I get an error saying that $template_dir is undefined.

[PHP] PHP6 Stable Release Schedule

Re: [PHP] how to strip empty lines out of a txt using preg_replace()
Sam Stelfox wrote:
The following snippet is untested and using Ash's regex (it is accurate
\s matches any white space). $content is what is getting stripped of the

$filtered = '';
foreach ($lines as $line) {

// Splitting on the PHP_EOL characters cause it to be removed be
sure to put it back
$filtered .= $line . PHP_EOL;

That isn't going to work. You missed your delimiters in the first arg
for preg_match(). It requires beginning and ending delimiters around
the regex.
I would try this
$lines = preg_split('|[\n\r]|', $content);
$filtered = '';
foreach ( $lines as $line ) {
$txt = trim( $line );
if ( ! empty( $txt ) ) {
$filtered .= $line;
}
}
It is much more intense to do the preg_match inside a loop. You should
only do it once, then use less intense function calls inside the loop.
warning: completely untested... have no example input you are using...

Well you have to access it as a global by either declaring it global in
the method (global $template_dir;) or by the superglobal
$GLOBALS['template_dir']. However this is probably not the preferred
way to do it.
I would either define it as a constant define('TEMPLATE_DIR',
'templates/') or you could pass $template_dir into the class constructor
and have it set as a class var, but I prefer the constant.

I briefly mentioned - I apologize for the brevity of that email because I was in a hurry - that a legitimate full text search engine is the right solution to this problem. The only problem with deploying a full text search engine is going to be the difficulty in the deployment and perhaps issues if you're on shared hosting (but then again I am of the opinion that those who choose to run with shared hosting dig their own graves in more ways than one). What a full text search engine gives you is flexibility in your searches, such that the initial question, when I read it, I thought Oh, someone will tell him to use Sphinx or Solr as both have special filters for word seperation and would handle this without any special instruction. Instead, this is never even brought up! Why was using a full text search engine to do this sort of thing - not to mention the other benefits that it would bring (responsiveness and flexibility in searching, speed, decreased use of MySQL, etc. etc.) - rejected so offhandedly? I can't actually think of a better way to do this without requiring a whole heap of overhead, either processing or programming. I've just sort of stopped in on this thread... but why isn't MySQL's FULLTEXT engine being considered? If I remember correctly, it's only on available on MyISAM table type.
