I have such code:
for ($j = 0; $j < mysql_num_rows($subcategoriesData); $j++)
{
$subcategoriesStrResult = mysql_fetch_array($subcategoriesData);
//echo $subcategoriesStrResult['title']."<br>";
$itemFeatures = array( $subcategoriesStrResult['title'] => $subcategoriesStrResult['path']);
array_push($arrayDataSubcategoryItems, $itemFeatures);
};
array_push($mainArrayForJSON, $item = array(
'parent_id' => $subcategoriesStrResult['parent'],
'level' => $subcategoriesStrResult['level'],
'items' => $arrayDataSubcategoryItems
));
After my $mainArrayForJSON is ready I'm trying to check the json-code by the simple echo
echo json_encode($mainArrayForJSON);
Meanwhile, to be sure that I get what I need I'm checking the single value of my string by the echo too (this string is commented now) - it works OK, I see on Chrome good readable text (in database this text is stored in utf8, of course).
But last call to echo for check the prepared JSON leads me to the next output:
[{"parent_id":"8-590","level":"3","items":[{"\u041c\u0435\u0442\u0430\u043b\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u043e\u0442\u043e\u043a BAKS (\u041f\u043e\u043b\u044c\u0448\u0430)":"8-590-1404"},{"\u041c\u0435\u0442\u0430\u043b\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u043e\u0442\u043e\u043a INPUK
So, I have no idea how to fix it - I tried to hardcode UTF-coding "SET NAMES ..." and called header(), and iconv() - last has no sense becouse of I'm sured that my text is in UTF8.
Please, help, thanks.
If you want to output your text on a web page, use javascript. And you'll get your Russian characters. For example:
<script type="text/javascript">
var a = "\u041c\u0435\u0442\u0430\u043b\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u043e\u0442\u043e\u043a BAKS (\u041f\u043e\u043b\u044c\u0448\u0430";
alert(a);
</script>

I'm building a simil web-service in php. This web service can read all record from a table of database and return a list of it in json format.
This is the code of my getArticoli.php file:
<?php
require_once('lib/connection.php');
$query_Articolo = "SELECT CodArticolo,NomeArticolo,Quantita,CodiceBarre, PrezzoAttuale, PrezzoRivenditore,PrezzoIngrosso
FROM VistaArticoli ";
$result_Articoli = $connectiondb->query($query_Articolo);
$answer = array ();
while ($row_Articoli = $result_Articoli->fetch_assoc()) {
$answer[] = ["id" => $row_Articoli['CodArticolo'],
"nome" => '"' . $row_Articoli['NomeArticolo'] . '"',
"quantita" => $row_Articoli['Quantita'],
"codiceBarre" => $row_Articoli['CodiceBarre'],
"codartFornitore" => $row_Articoli['CodiceBarre'],
"PrezzoAttuale" => $row_Articoli['PrezzoAttuale'],
"prezzoRivenditore" => $row_Articoli['prezzoRivenditore'],
"prezzoIngrosso" => $row_Articoli['prezzoIngrosso']];
}
//echo "fine";
echo json_encode($answer);
?>
Now, if I try to open this page, with this url: http://localhost/easyOrdine/getArticoli.php
I don't get the json_response.
In the table of database, there are 1200 records. If I try to insert an echo message in while cycle, I see it.
I have noticed that the problem lays with this field:
"nome"=>'"'.$row_Articoli['NomeArticolo'].'"'
If I remove this field from the response, I can correctly see the json response.
In this field there are any character from a-z/0-9 and special character like "/ * ? - and other".
It is possible that these special character can cause any error of the json answer?
EDIT
I have limit at 5 my query and this is the response:
[{"id":"878","0":"ACCESSORIO PULIZIA PUNTE DISSALDANTE 3 MISURE","quantita":"1","codiceBarre":"DN-705100","codartFornitore":"DN-705100","PrezzoAttuale":"14.39","prezzoRivenditore":null,"prezzoIngrosso":null},
{"id":"318","0":"ACCOPPIANTORE RJ11 TELEFONICO VALUELINE VLTP90920W","quantita":"20","codiceBarre":"5412810196043","codartFornitore":"5412810196043","PrezzoAttuale":"0.68","prezzoRivenditore":null,"prezzoIngrosso":null},

{"id":"310","0":"ACCOPPIATORE RJ45 VALUELINE VLCP89005W","quantita":"8","codiceBarre":"5412810228843","codartFornitore":"5412810228843","PrezzoAttuale":"0.38","prezzoRivenditore":null,"prezzoIngrosso":null},
{"id":"311","0":"ACCOPPIATORE USB2 VALUELINE VLCP60900B","quantita":"5","codiceBarre":"5412810179596","codartFornitore":"5412810179596","PrezzoAttuale":"1.80","prezzoRivenditore":null,"prezzoIngrosso":null}]
First, remove those extraneous quote characters. You don't need them and they could hurt you down the road:
while ($row_Articoli = $result_Articoli->fetch_assoc()) {
$answer[] = [
"id" => $row_Articoli['CodArticolo'],
"nome" => $row_Articoli['NomeArticolo'],
"quantita" => $row_Articoli['Quantita'],
"codiceBarre" => $row_Articoli['CodiceBarre'],
"codartFornitore" => $row_Articoli['CodiceBarre'],
"PrezzoAttuale" => $row_Articoli['PrezzoAttuale'],
"prezzoRivenditore" => $row_Articoli['prezzoRivenditore'],
"prezzoIngrosso" => $row_Articoli['prezzoIngrosso']
];
}
Then, run your query as is (without the LIMIT), and afterwards run echo json_last_error_msg()';, which could give you a hint to what's going on.
Also, being that your DB is in italian, maybe its encoding is not UTF-8. json_encode requires UTF-8 encoded data. So you may try to utf8_encode your article names before json_encoding the array:
"nome" => utf8_encode($row_Articoli['NomeArticolo']),
And see what you get.
Changing your DB charset to 'utf8mb4' could do the trick as well, and it is usually recommended.
I want to save xml document in mysql database as below:
$_docId= $this->getRequest()->getParam('docId', 0);
$_slmData = '<SLM_form_v2 id="slmform"><group_1_1><section1_1/><name1_1>sdfds</name1_1>
enter code here<localname1_2/><selectcountry_1_3>Algeria</selectcountry_1_3></group_1_1>
enter code here<group_1_2><main_doc/><name_doc1>gdgf gfh f</name_doc1><sex_doc1>Male
</sex_doc1><name_institution_1>fsdgdfg</name_institution_1><address_institution_1>gdgfdgfd
</address_institution_1>....';
$_docMapper = new Model_Mapper_XMLDoc();
$_docModel = new Model_XMLDoc();
$_docModel ->doc_data = Zend_Json::encode($_docData);
if ($_docId != 0) {
$_docModel->id = $_docId;
$_docMapper->update($_docModel->toArray(), 'id = ' . $_docId);
$_action = 'update';
} else {
$_docMapper->insert($_docModel->toArray());
$_lastId = $_docMapper->getAdapter()->lastInsertId(); //gets the id of the last inserted record
$_action = 'add';
}
$this->_helper->json->sendJson(array(
'message' => 'success',
'id' => $_lastId,
'action' => $_action
));
It is stored in the db:
INSERT INTO crpcoreix.tbl_xml_doc (slm_data, web_gis_fk) VALUES ('"<SLM_form_v2 id=\\"slmform\\"><group_1_1><section1_1\\/><name1_1>sdfds<\\/name1_1><localname1_2\\/><selectcountry_1_3>Algeria<\\/selectcountry_1_3><\\/group_1_1><group_1_2><main_doc\\/><name_doc1>gdgf gfh f<\\/name_doc1><sex_doc1>Male<\\/sex_doc1><name_institution_1>fsdgdfg<\\/name_institution_1><address_institution_1>gdgfdgfd gdgf<\\/address_institution_1>...', null);
When I'm trying to read the data from the database and display the encoded xml tags the output miss the first part ("<SLM_form_v2 id=\\"slmform\\"><group_1_1><section1_1\\/><name1_1>...) the first part
Array
(
[id] => 1
[xml_data] => "sdfds<\/name1_1>Algeria<\/selectcountry_1_3>...'
[web_gis_fk] =>
)
Please advice how to fix and if there is a better way to store xml documents in database.
Thanx,
first is first you need to double check your given xml syntax, whether its correct or not.
Zend_Json includes a static function called Zend_Json::fromXml(). so
you would better manage to use it instead of Zend_Json::encode when
you encode XML
This function will generate JSON from a given XML input.
This function takes any arbitrary XML string as an input parameter. It also takes an optional Boolean input parameter to instruct the conversion logic to ignore or not ignore the XML attributes during the conversion process.
If this optional input parameter is not given, then the default behavior is to ignore the XML attributes. This function call is made as shown below:
$jsonContents = Zend_Json::fromXml($xmlStringContents, true);
Give it a try but again check your XML syntax
I am trying to use the tablesorter pager plugin with AJAX but run into som problemes (or limitations) when trying to handle the AJAX request in my php backend.
If eg. the table is set up with a default sorting of
sortList: [ [0,1], [1,0] ]
I will get a URL like this on my AJAX request:
page=0&size=50&filter=fcol[6]=batteri&sort=col[0]=1&col[1]=0
In my php back end I do a
$cur_sort = $_GET['sort']
and get
col[0]=1
So the last part is missing - I guess since it contains a & char.
How do I get the entire sort string?
That said how is the string col[0]=1&col[1]=0 best parsed? I need to extract the info that col 0 is to be sorter DESC and col 1 ASC.
You can try this;
parse_str($_SERVER['QUERY_STRING'],$data);
It will parse the url to an array;
Also; you should use empty [] instead of [1] and [0]
See more here: parse_str()
Example:
$str = "page=0&size=50&filter=fcol[6]=batteri&sort=col[0]=1&col[1]=0";
parse_str($str, $output);
echo $output['page']; // echo 0
And to answer your question; it is correct; is echoing col[0]=1 because you are dividing with & see here:
&sort=col[0]=1 & col[1]=0;
An advice; use more names, instead.
You could use
&sort[]=1&sort[]=0;
UPDATE:
To access the last one; you should do, simply;
$_GET['col'][1];
If you want to access, the last number in
$_GET['sort'];
You can do this;
$explode = explode('=',$_GET['sort']);
$end = end($explode);
echo $end; //it will outout 1
If you print your entire query_String, it will print this;
Array
(
[page] => 0
[size] => 50
[filter] => fcol[6]=batteri
[sort] => col[0]=1
[col] => Array
(
[1] => 0
)
)
I'm not sure how the ajaxUrl option is being used, but the output shared in the question doesn't look right.
I really have no idea how the string in the question is showing this format:
&sort=col[0]=1&col[1]=0 (where did sort= come from?)
&filter=fcol[6]=batteri (where did filter= come from?)
If you look at how you can manipulate the ajaxUrl option, you will see this example:
ajaxUrl: "http://mydatabase.com?page={page}&size={size}&{sortList:col}&{filterList:fcol}"
So say you have the following settings:
page = 2
size = 10
sortList is set to [[0,1],[3,0]] (1st column descending sort, 4th column ascending sort)
filters is set as ['','','fred']
The resulting url passed to the server will look like this:
http://mydatabase.com?page=2&size=10&col[0]=1&col[3]=0&fcol[2]=fred
The col part of the {sortList:col} placeholder sets the sorted column name passed to the URL & the fcol part of {filterList:fcol} placeholder sets the filter for the set column. So those are not fixed names.
If the above method for using the ajaxUrl string doesn't suit your needs, you can leave those settings out of the ajaxUrl and instead use the customAjaxUrl option to modify the URL as desired. Here is a simple example (I know this is not a conventional method):
ajaxUrl: "http://mydatabase.com?page={page}&size={size}",
// modify the url after all processing has been applied
customAjaxUrl: function(table, url) {
var config = table.config,
// convert [[0,1],[3,0]] into "0-1-3-0"
sort = [].concat.apply( [], config.sortList ).join('-'),
// convert [ '', '', 'fred' ] into "--fred"
filter = config.lastSearch.join('-');
// send the server the current page
return url += '&sort=' + sort + '&filter=' + filter
}
With the same settings, the resulting URL will now look like this:
http://mydatabase.com?page=2&size=10&sort=0-1-3-0&filter=--fred
This is my own best solution so far, but it's not really elegant:
if (preg_match_all("/[^f]col\[\d+]=\d+/", $_SERVER['QUERY_STRING'], $matches)) {
foreach($matches[0] AS $sortinfo) {
if (preg_match_all("/\d+/", $sortinfo, $matches)) {
if(count($matches[0]) == 2) {
echo "Col: ".$matches[0][0]."<br/>";
echo "Order: ".$matches[0][1]."<br/>";
}
}
}
}
It gives me the info I need
Col: 0
Order: 1
Col: 1
Order: 0
But is clumbsy. Is there a better way?
I am using a PHP script (this one) to generate a JSON file for a Google Map.
this is the PHP code (note: I am using Laravel):
<?php
$query = "SELECT id, info, lat, lng FROM places";
$results = DB::select($query);
$myLocations = array();
$i = 0;
$testLoc = array('loc95' => array( 'lat' => 15, 'lng' => 144.9634 ));
foreach ($results as $result)
{
$myLocation = array(
'loc'.++$i => array(
'lat' => round((float)$result->lat, 4),
'lng' => round((float)$result->lng, 4)
));
$myLocations += $myLocation;
}
$myLocations += $testLoc;
echo json_encode($myLocations);
?>
and this is the output:
{"loc1":{"lat":45.4833,"lng":9.1854},"loc2":{"lat":45.4867,"lng":9.1648},"loc3":{"lat":45.4239,"lng":9.1652},"loc95":{"lat":15,"lng":144.9634}}
ok. the script I use to put the JSON data in a Google Map, unfortunately, keeps ignoring any data coming from the MySQL database, and shows only the test data place(s). I have tried to swap data, to put in test data the same info found in database... nothing, I keep seeing only the test data.
but, really: I cannot figure out why. What am I missing... ?
You wrote that you're using another script and that the other script only shows the testlocations on google maps.
My guess is that you didn't update the other script to your needs, specifically my crystal ball is telling me that you still have this line in there:
setMarkers(locs);//Create markers from the initial dataset served with the document.
In your question you only showed the part which worked and I agree, but you only mentioned that "something else" isn't working. If you want an answer for that part, try reprashing your question and include the parts which cause you problems.
I am primarily a PHP developer and have limited experience with Perl.
I was tasked with writing a queue script in Perl which checks against a database, and that is all working out great.
The problem I have is that in the Perl script I need to include a database hostname and password.
Right now I have them hard coded, which works fine, but my PHP application uses a global PHP array which holds the database hostname and password.I'd like to be able to use this PHP array in my Perl script.
Here is my PHP array
<?php
return array(
'database' => array(
'master' => array(
'hostname' => 'fd35:4776:6804:2:a::1',
'password' => 'password'
),
'slave' => array(
'hostname' => 'fd35:4776:6804:2:2::2',
'password' => 'password',
'profile' => true
)
)
);
I've tried searching with Google and have read many random posts on line, but I have yet been able to come up with a solution.
Does anyone have any ideas which I could try? If I'm missing any additional input, let me know and I can provide it.
Edit
Hopefully I worded this properly. How would I go about including this PHP array file so that I can manipulate it with Perl?
Alternative solutions are welcome too!
You've discovered one of the many reasons why code makes for bad config files. You should move the information to an actual config file, and access that file from both that .php file and from Perl.
JSON would make a decent file format here.
{
"database": {
"master": {
"hostname": "fd35:4776:6804:2:a::1",
"password": "password"
},
"slave": {
"hostname": "fd35:4776:6804:2:2::2",
"password": "password",
"profile": true
}
}
}
The Perl code would be
use JSON::XS qw( decode_json );
open (my $fh, '<:raw', $config_path)
or die("Can't open config file $config_path: $!\n");
my $file; { local $/; $file = <$fh>; }
my $config = decode_json($file);
On the PHP side, just replace the contents of the file you showed in your post with code to read the config file. I don't know PHP, but it should be quite simple. A quick search shows it might be
return json_decode(file_get_contents($config_path));
It would be simple to provide a short PHP program that dumps the array to a file in JSON format. That file can then be read from Perl using the JSON module.
This is all that is necessary.
<?php
$array = include 'array.php';
$fh = fopen('array.json', 'w');
fwrite($fh, json_encode($array));
fclose($fh);
?>
The resultant JSON file can then be read in a Perl program, like so:
use strict;
use warnings;
use JSON 'from_json';
my $data = do {
open my $fh, '<', 'array.json' or die $!;
local $/;
from_json(<$fh>);
};
use Data::Dump;
dd $data;
output
{
database => {
master => { hostname => "fd35:4776:6804:2:a::1", password => "password" },
slave => {
hostname => "fd35:4776:6804:2:2::2",
password => "password",
profile => bless(do{\(my $o = 1)}, "JSON::XS::Boolean"),
},
},
}
There is PHP::Include, which uses a source filter to let you have PHP blocks in your Perl code to declare variables. It also has a read_file() function that applies such a filter to a single PHP file.
But it seems to expect that your PHP has assignments (e.g. $config = array('database' => array(...) and changes those to Perl variable declarations.
In a few minutes of playing with it, I couldn't get it to do anything useful with your PHP code that uses return.
If you want a more "native Perl" solution, you can pretty much* just search and replace all your "array(" and their matching ")" to "{" and "}". That'll give you a perl datastructure called a "hash of hashes" (note: Unlike PHP, Perl refers to arrays with integer indicies as arrays (and uses the # sigil to denote variables containing them), but refers to array-like things with string indicies as "hashes" (and uses the % sigil to denote variables containing them)). The Perl keywords/concepts you probably want to read up on are:
Perl Data Structures: http://perldoc.perl.org/perldsc.html
and specifically the Hash Of Hashes section: http://perldoc.perl.org/perldsc.html#HASHES-OF-HASHES
and if you dont understand what $hashref = \%hash and %hash{key} and $hashref->{key} mean in Perl, you'd want to read http://perldoc.perl.org/perlref.html
Example code (note how similar the getConfig subroutine is to your PHP code):
#!/usr/bin/perl
use strict;
use warnings;
my $config=getConfig();
print "Database master host = " . $config->{database}{master}{hostname};
print "\n";
print "Database master password = " . $config->{database}{master}{password};
print "\n";
print "Database slave profile = " . $config->{database}{slave}{profile};
print "\n";
sub getConfig{
return {
'database' => {
'master' => {
'hostname' => 'fd35:4776:6804:2:a::1',
'password' => 'password'
},
'slave' => {
'hostname' => 'fd35:4776:6804:2:2::2',
'password' => 'password',
'profile' => 'true'
}
}
};
}
I said "pretty much", because your sample data used the bare word 'true' for the slave->profile value - that's a syntax error in Perl - you can change it to a bare 1, or quote the value as "true" to make it work. In Perl, the digit zero, the string "0" or the empty/nul string "" all evaluate to "false" in a boolean context, anything else evaluates to "true". Take care if you choose to automate PHP to Perl translation, there may be other PHP-isms which could catch you out like that.
So much good information here and it helped me out quite a bit to come up with a working solution.
Here is the perl script I've got working:
#!/usr/bin/perl
use PHP::Include;
include_php_vars( 'config.local.php' );
my $test = \%config;
print $test->{'database'}->{'master'}->{'hostname'};
I also took the PHP array and changed it so that it no longer return array() but $config = array() and then return $config;
This did the trick for me. Thank you!
