Re: [PHP] parsing select multiple=multiple
I *have* heard claims that something like this is preferrable, though: if (FALSE === $variable) I believe I read a comment somewhere once that writing your IF statements that way helped to trigger an error message when the coder forgot to use the double equal sign (==) in the statement. I haven't adopted it yet, but I think that's the sole reason for it. Basically you can't make an assignment (=) to a constant or some non-variable target. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

}
Question 1: when did we have to add [] to a input name to turn it into an
array?
input type=checkbox name=DPRlocationdetails[] value=Unknown
According to phpinfo() it still comes out as $_POST['DPRlocationdetails']
without [].
Are the [] necessary?
[] are necessary when you want to return multiple values for a form
field, or collection of form fields such as checkbox. AFAIK, this has
always been the case with PHP. See
https://gist.github.com/tamouse/5002728

Question 2:
I was looking at some code in the Manual, where someone used isset and
is_array.
How necessary is if(isset($_POST['DPRlocationdetails']))
and then to use: if(is_array($_POST['DPRlocationdetails']))
That seems like over kill?
It's more defensive, in the case where someone may be by-passing your
form to send things in.
--
Question 3:
My code works, perfectly.
Then there must be no questions. :)
In this case, I decided to attack some check-boxes
first. The resulting function will work for select multiple too..
Does anyone see me doing something wrong in my code below?
My questions are:
Is this the only way to pass Unknown, Family Home or Apartment into
the function?
Is this correct?
if ($_POST['DPRlocationdetails'] == Unknown)
Somebody once told me I had to do it this way?
if (Unknown == $_POST['DPRlocationdetails'])
In this scenario, these are equivalent. There is no preference of one
over the other.
I *have* heard claims that something like this is preferrable, though:
if (FALSE === $variable)
But I think that may have been due to some misunderstanding of
precedences in the following sort of scenario:
if (FALSE === ($result = some_function())
where if done this way:
if ($result = some_function() === FALSE)
was giving them bad results.

The [] are necessary if there are going to be multiple occurrences of an
input with the same name, hence the [] to allow your php script to
extract all of the occurrences.
Using isset and is_array comes in handy to help you handle the incoming
var properly. If it IS set, you then have to check if there is only one
value (hence a string) or if there are multiple values (an array).

Not exactly that -- I think I goofed up your variable names.
$DPRpriority is the set of values that can be selected, and DPRType
are the values returned from the form.
Here's a small snippet showing how it works, I hope:

$DPRpriority = array(array('name' = Crimes Against Persons,
'selected' = false),
array('name' = Disturbances, 'selected' = false),

false),
array('name' = Crimes Against Property, 'selected' =
false),
array('name' = Accidents / Traffic Problems, 'selected'
= false),
array('name' = Suspicious Circumstances, 'selected' =
false),
array('name' = Morality / Drugs, 'selected' = false),
array('name' = Miscellaneous Service, 'selected' =
false),
array('name' =Alarms, 'selected' = false));
echo h1Initial value of DPRpriority:/h1ul\n;
foreach ($DPRpriority as $item = $value) {
echo li .$item.: .$value['name']. selected:

}
echo /ul\n;

[PHP] Parsing a simple sql string in php
Hiya, has anyone had any experience with parsing a string of sql to break it down into its component parts? At the moment I'm using several regex's to parse a string, which works, but I'm sure there's a more elegant solution. The general idea is to produce a nice looking page giving details of updated fields and values. I'm only concerned with update statements really, and the queries are very simple, operating on one table at a time, with no sub queries or selects. Thanks in advance if anyone is able to suggest anything! Thanks Ash -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The usual way to approach this problem is to tokenise the input, then take each token at a time and branch where there are several options for what comes next. As you go along, build up a data structure that represents the data you need.

[PHP] Parsing a phrase
Hello all. I have a page where the user can enter a search phrase and upon submitting, the search phrase is queried in MySQL. However, I need to modify is so each word in the phrase is searched for... not just the exact phrase. So, big blue hat will return results like: A big hat - blue in color Hat - blue, big SQL would look like WHERE (item_description like %big% and item_description like %blue % and item_description like %hat% ) So, via PHP, what is the best way to extract each word from the search phrase to it's own variable so I can place them dynamically into the SQL statement.

[PHP] Parsing JSON; back-slash problem
This seems like a pretty basic question, but it has me stumped.
Here's my scenario: I'm using Douglas Crockford's JSON2.js to parse an
object in JavaScript, which I then pass to a PHP script to store in a
file. I use JSON.stringify() on the object, which logs to the console
as this:
{employees:{data:{John:{fname:John,lname:Doe,city:Toronto,country:Canada
Then I use the jQuery POST function to send it to a PHP script. Before
doing anything with it in PHP, I log the received value to the
console, and this is what I get:
{\employees\:{\data\:{\John\:{\fname\:\John\,\lname\:\Doe\,\city\:\Toronto\,\country\:\Canada\
The problem is, when I call the script to retrieve this data from a
file, JSON.parse can't parse it because of the back-slashes. I'm
pretty sure my problem is on the PHP side (since it's fine coming out
of JS); what do I need to do to fix this? is a preg_replace enough?

Turn off magic quotes, as it looks like they are enabled on your server.
You can turn them off from the .htaccess file if you don't have access
to the php.ini

[PHP] newbie question - php parsing
Hi all,
A little doubt caught me while I was writing this snippet of code for
a wordpress template:
?php if (the_title('','',FALSE) != 'Home') { ?
h2 class=entry-header?php the_title(); ?/h2
?php } ?
I always thought that php was called only between the ?php ? tags,
and I'm pretty sure that's right, while HTML code was simply wrote in
document as is, without further logic.
Now, I can't figure out how this snippet works: I mean, shouldn't HTML
code be simply put on document, as it is outside php invoke?
Effectively if the title of page is 'Home', the HTML part is totally
skipped.
Is the if construct that does all the magic inside?

Hey,
I want to parse a href-attribute in a given String to check if there
is a
relative link and then adding an absolute path.
Example:
$string = 'a class=sample [...additional attributes...]
href=/foo/bar.php ';
I tried using regular expressions but my knowledge of RegEx is very

Things to consider:
- $string could be quite long but my concern are only those href
attributes
(so working with explode() would be not very handy)
- Should also work if href= is not using quotes or using single quotes
- link could already be an absolute path, so just searching for href=
and
then inserting absolute path could mess up the link
Any ideas? Or can someone create a RegEx to use?
Just spitballing here, but this is probably how I would start:
RegEx pattern: /a.*? href=(.+?)/ig
Then, using the capture group, determine if the href attribute uses quotes
(single or double, doesn't matter). If it does, you don't need to worry about
splitting the capture group at the first white space. If it doesn't, then you
must assume the first whitespace is the end of the URL and the beginning of
additional attributes, and just grab the URL up to (but not including) the
first whitespace.
So...
?php
# here is where $anchorText (text for the a tag) would be assigned
# here is where $curDir (text for the current directory) would be assigned
# find the href attribute
$matches = Array();
preg_match('#a.*? href=(.+?)#ig', $anchorText, $matches);
# determine if it has surrounding quotes
if($matches[1][0] == '\'' || $matches[1][0] == '')
{
# pull everything but the first and last character
$anchorText = substr($anchorText, 1, strlen($anchorText) - 3);
}
else
{
# pull up to the first space (if there is one)
$spacePos = strpos($anchorText, ' ');
if($spacePos !== false)
$anchorText = substr($anchorText, 0, strpos($anchorText, ' '))
}
# now, check to see if it is relative or absolute
# (regex pattern searches for protocol spec (i.e., http://), which will be

if($anchorText[0] != '/' preg_match('#^\w+://#', $anchorText) == 0)
{
# add current directory to the beginning of the relative path
# (nothing is done to absolute paths or URLs with protocol spec)
$anchorText = $curDir . '/' . $anchorText;
}

Hey,
I want to parse a href-attribute in a given String to check if there
is a
relative link and then adding an absolute path.
Example:
$string = 'a class=sample [...additional attributes...]
href=/foo/bar.php ';
I tried using regular expressions but my knowledge of RegEx is very
limited.
Things to consider:
- $string could be quite long but my concern are only those href
attributes
(so working with explode() would be not very handy)
- Should also work if href= is not using quotes or using single quotes
- link could already be an absolute path, so just searching for href=
and
then inserting absolute path could mess up the link
Any ideas? Or can someone create a RegEx to use?
Just spitballing here, but this is probably how I would start:
RegEx pattern: /a.*? href=(.+?)/ig
Then, using the capture group, determine if the href attribute uses quotes
(single or double, doesn't matter). If it does, you don't need to worry
about splitting the capture group at the first white space. If it doesn't,
then you must assume the first whitespace is the end of the URL and the
beginning of additional attributes, and just grab the URL up to (but not
including) the first whitespace.
So...
?php
# here is where $anchorText (text for the a tag) would be assigned
# here is where $curDir (text for the current directory) would be assigned
# find the href attribute
$matches = Array();
preg_match('#a.*? href=(.+?)#ig', $anchorText, $matches);
# determine if it has surrounding quotes
if($matches[1][0] == '\'' || $matches[1][0] == '')
{
# pull everything but the first and last character
$anchorText = substr($anchorText, 1, strlen($anchorText) - 3);
}
else
{
# pull up to the first space (if there is one)
$spacePos = strpos($anchorText, ' ');
if($spacePos !== false)
$anchorText = substr($anchorText, 0, strpos($anchorText, ' '))
}
# now, check to see if it is relative or absolute
# (regex pattern searches for protocol spec (i.e., http://), which will be
# treated as an absolute path for the purpose of this algorithm)
if($anchorText[0] != '/' preg_match('#^\w+://#', $anchorText) == 0)
{
# add current directory to the beginning of the relative path
# (nothing is done to absolute paths or URLs with protocol spec)
$anchorText = $curDir . '/' . $anchorText;
}
echo $anchorText;

Wow, that's alot! This should work with or without quotes and assumes
no spaces in the URL:
$prefix = http://example.com/;;
$html = preg_replace(|(href=['\]?)(?!$prefix)([^'\\s]+)(\s)?|,
$1$prefix$2$3, $html);
Might need to keep a preceding slash out of there:

I believe the OP wanted to leave already-absolute paths alone (i.e., only
convert relative paths). The regex does not take into account fully-qualified
URLs (i.e., http://www.google.com/search?q=php) and it does not determine if a
given path is relative or absolute. He was wanting to take the href attribute
of an anchor tag and, **IF** it was a relative path, turn it into an absolute
path (meaning to append the relative path to the absolute path of the current
script).
That was my understanding. Perhaps you saw it differently, but I don't believe
your pattern is enough to accomplish what the OP was asking for--hence a lot
of code was in my reply. ;)
Believe me, I'm the first guy to hop on the do it with a regex! bandwagon...

I see that now. I didn't notice the negative look-ahead the first go 'round.
However, I still have qualms with it. :) You are only checking for http://, and
only for the local server. What I meant by absolute path was, for example,
/index.php (the index in the root directory of the server) as opposed to
somefolder/index.php (the index in a subfolder of the current directory named
'somefolder').
* http://www.google.com/search?q=php ... absolute path (yes, it's a URL, but
treat it as absolute)
* https://www.example.com/index.php ... absolute path (yes, it's a URL, but to
the local server)
* /index.php ... absolute path (no protocol given, true absolute path)
* index.php ... relative path (relative to current directory on current server)
* somefolder/index.php ... relative path (same reason)
That is indeed a nifty use of look-ahead, though. That will work for any anchor
tag that doesn't reference the server (or any other server) with a protocol
spec preceding it. However, if you want to run it through an entire list of
anchor tags with any spec (http://, https://, udp://, ftp://, aim://, rss://,
etc.)--or lack of spec--and only mess with those that don't have a spec and
don't use absolute paths, it needs to get a bit more complex. You've convinced
me, however, that it can be done entirely with one regex pattern.

Re: [PHP] Parsing HTML href-Attribute
Hi Edmund,
You want a regex that looks something like this:
$result = preg_replace('%(href=)(|\')(?!c:/)(.+?)(|\')%',
'\1\2c:/my_absolute_path\3\4', $subject);
This example assumes that your absolute path begins with c:/. You would
change this to whatever suits. You would also change c:/my_absolute_path
to be whatever appropriate value indicates the absolute path element that
you want to prepend.
Note: this will NOT accound for hrefs that are not encapsulated in either '
or . The problem being that while you can probably predictably how the
substring starts, it would be more difficult to determine how it ends,
unless you can provide a white list of file extensions for the regex (ie, if
you know you only ever link to, for example, files with .php and or .html
extensions). In that case, you probably could alter the regex to test for
these instead of a ' or .

href=/foo/bar.php ';
I tried using regular expressions but my knowledge of RegEx is very
limited.
Things to consider:
- $string could be quite long but my concern are only those href attributes
(so working with explode() would be not very handy)
- Should also work if href= is not using quotes or using single quotes
- link could already be an absolute path, so just searching for href= and
then inserting absolute path could mess up the link
Any ideas? Or can someone create a RegEx to use?
Thanks
Re: [PHP] Parsing Strings
Why not preg_split ( http://nz.php.net/manual/en/function.preg-split.php ):
$str = 'SCOTTSDALE, AZ 85254';
$ar = preg_split('/,? ?/', $str); //optional comma, followed by optional
space
// $ar = array('SCOTTSDALE', 'AZ', '85254');

$xp-setParameter('', array('pos' = $_GET['pos']) );

$file in this case is just a single filename, no XML. My input data has
a list of filenames, the 'pos' argument from the URI identifies one I

So here you're advocating loading the XML document into PHP to add an
element, then convert the XML into something else, for PHP to read back
in (not forgetting my original question said I need PHP to do some
operations on the XML.) Do you see why I just wanted a way to extract
the parts of the XML document I needed? This example is actually making
something unnecessarily complex just because XSL is deemed to be the
best way to work with XML.
I'm not saying that XSL is a bad thing, I've used it many times before
to convert various document formats, I just think that for what I
needed, XSL doesn't really suit the task at hand.

No, not at all. 1) no element is added, 2) the document is not
loaded 'into' PHP and 3) PHP 'reads back' output of about 30 bytes (a
filename + path).
None of the XSL+XML happens inside of PHP - it's done through the XSL
extension which is essentially all calls to libxslt.
Do you see why I just wanted a way to extract the parts of the XML
document I needed? This example is actually making something
unnecessarily complex just because XSL is deemed to be the best way to
work with XML.
Ash, my example above extracts a single element (specified by 'pos')
from an XML-document - it's all done by a standards-compliant XSLT
style-sheet, and very effectively so. The 8 lines of PHP code to
invoke the XSL conversion are virtually 'standard' too. I'm having a
hard time appreciating why that is better done by combining
somebodyelses custom code with your own custom code.
I'm not saying that XSL is a bad thing, I've used it many times before
to convert various document formats, I just think that for what I

I understand what you're saying, I just haven't heard a good argument

Per Jessen wrote: Ashley Sheridan wrote: [/snip] :p XSL(T) an xslt processor, along with an XSLT stylesheet, should be used to transform XML documents in to other XML, human readable or structured documents. DOM a class implementing the DOM interface should be used to traverse, analyse and extract information from an HTML or valid XML document for use in a computer program or to convert values to there primitive counterparts. E4X ideally E4X should be used where available as this provides native XML support, treating xml documents as primitive types and thus providing a faster, more acceptable way of using XML as building blocks in a computer program. PHP Support As far as I am aware PHP does not have any kind of supoort for ECMAScript let alone E4X so this can be removed from the discussion as quickly as it was entered. Leaving just XSL and DOM. Non programmatic XML usage: For all non programatic usage of XML documents (ie transforming the document in to html, a human readable document or another xml structure) then XSLT should be used. Examples: -Integrating the data from an RSS feed into an (X)HTML page and outputing it to a client application (non persistant stuctured document) -Converting an XML Packet into an OOo document and saving it in a file system (persistant stuctured document) Programmatic XML Usage: For all programmatic usage of XML, when you need to take the data from an XML document and use node or attribute values in a program, then the DOM API should be used. Examples: -Extracting the structured object data encapsulated in a SOAP response and using it to instantiate a class for further usage. (non persitant structured data for use by a computer program) -Converting the data values in a structured XML document, (lets say from the WOW Armory), into primitive values and then persiting the data into database tables. (persitant structured data for use by a computer program) Grey Areas: If you are using an ORM which uses XML schemas to define data objects then xslt may be the more appropriate choice, this would probably incur an extra XSL transformation to then convert the ORM's schema into an object. One could argue that XSLT could be used to transform the XML document in to an SQL string, however this would not allow (or certainly limited allowance of) programatic manipulation / validation of the data prior to injection into the SQL string. Alternatives: Regex or string parsing on an XML document can often lead to far faster but less reliable extraction of data for use in a script, probably so common in PHP as it's loosley typed language :p Obviously though if the XML document structre changes, you're pretty much stuffed - thus any form of native or strongly typed support is a far better option. Suggestion: Ashley, TBH the approach I'd take (if I had time) would be to create class(es) for the data, then create XML documents representing the object structure of each class, write methods using the DOM API to extract data from my XML documents and instatiate the class(es) with it. At this point I'd have an app that need never change. Then I'd drop in a simple XSLT stylesheet to transform the remote XML document in to my local structured xml documents and use the XSL processor to run this transform. Thus if ever the remote document structure changed all I'd have to do is quickly edit the XSLT stylesheet. But whatever you're cool with, a simple regex xml to array convertor is normally the fastest and most transportable way of doing this (ie it'll generally work on php 4 and 5 on any server); and when you're not using a pre-compiled language you need to give much weight to these things.

I think it is very odd that no-one else is advocating XSL in this case. Extracting information from an XML file is just another way of converting it, which is exactly what XSL is good at. I can't imagine how using a pile of custom PHP code is going to be more efficient than writing a simple XSL stylesheet according to recognised standards etc. Just my opinion of course. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Parsing XML
Hi All, I've run into a bit of a problem. I need to parse some fairly detailed XML files from a remote website. I'm pulling in the remote XML using curl, and that bit is working fine. The smaller XML documents were easy to parse with regular expressions, as I only needed bit of information out of them. The live server I'm eventually putting this onto only has domxml for working with XML. I've been trying to find the pecl extension for this to install on my local machine, but the pecl.php.net site is a bit nerfed for this extension (I'm getting a file not found error message.) Do any of you have a copy of this extension, or failing that, a suggestion of how I can parse XML files without having to install anything on the remote server, as I do not have that level off access to it.

[PHP] parsing form with a website question...
Hi guys... Got a question that I figured I'd ask before I reinvent the wheel. A basic website has a form, or multiple forms. within the form, there might be multiple elements (lists/select statements, etc...). each item would have a varname, which would in turn be used as part of the form action, to create the entire query... sort of like: form action=test.php? option name=foo foo=1 foo=2 foo=3 foo=4 /option option name=cat cat=1 cat=2 cat=3 /option /form so you'd get the following urls in this psuedo example: test.php?foo=1cat=1 test.php?foo=1cat=2 test.php?foo=1cat=3 test.php?foo=2cat=1 test.php?foo=2cat=2 test.php?foo=2cat=3 test.php?foo=3cat=1 test.php?foo=3cat=2 test.php?foo=3cat=3 test.php?foo=4cat=1 test.php?foo=4cat=2 test.php?foo=4cat=3 i'm looking for an app that has the ability to parse any given form on a web page, returning the complete list of possible url combinations based on the underlying elements that make up/define the form... anybody ever seen anything remotely close to this...??? i've been research crawlers, thinking that this kind of functionality would already exist, but so far, no luck! thanks -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

won't break it when it used in mail($to, MMH Suggestion, $message,
$headers); below is my snippet of code, but is there a better way to
parse the text for special characters. what about if I were to have the
$message inserted into a mysql field? how would I need to handle
special characters that way?

So far I've found this: http://us.php.net/manual/en/ref.xml.php Which has some samples on, but nothing that I see will take a DTD file and parse the XML accordingly.

Re: [PHP] Parsing XML with DTD
Hey Jochem all, Thanks much for this tip. I will check it out. A little further reading looks like PEAR provides some XML and DTD capabilities? Anyone have any experience with this? Also, the reason I asked about the DTD is that these XML files are really extensive, providing lots of varied info about literature, history, a whole ton of topics, so I thought parsing the DTD will be necessary to know what kinds of data I'm really looking at. I'll check out Jochem's suggestion now, but would also like to hear if anyone has used PEAR, and also about the need for the DTD for big, complicated XML files. Would it be helpful if I pasted one of the XML files to the list? Thanks again!
