How can I get element using xpath? - php

I'm trying to get some data from a HTML
$xdata = simplexml_import_dom($doc);
$datas = $xdata->xpath("//*[#class='proglist']");
$aData = array();
foreach($datas as $data)
{
$rightdatas = $data->xpath("*[#class='progright']");
$rt = $rightdatas[0];
print_r($rt);
$content = $rt->xpath("*[#class='progrighthead']");
print_r($content );
}
If I'm printing out the content of the $rt than the progrighthead class is there, but the $content variable is empty. Why?
Why do I receiving the same result for the following syntax?
$xdata = simplexml_import_dom($doc);
$datas = $xdata->xpath("//*[#class='proglist']");
$aData = array();
foreach($datas as $data)
{
$rightdatas = $data->xpath("*[#class='progright']");
$rt = $rightdatas[0];
print_r($rt);
$content = $rt->xpath("*[#class='progrighthead']");
}
and
$datas = $xdata->xpath("//*[#class='progrighthead']");

progrighthead is not a child of progright, but a descendant. Use
$rt->xpath(".//*[#class='progrighthead']");
Putting // at the beginning means searching from the root, not from the current element.

How can I array_chunk mysqli results into chunks of 100 at a time

Is there a way I can Array_chunk mysqli results, I am looping messages from a table and later pass the values into a method "Sms" The method will create a List of Sms objects which I pass through a function SendBatchSMS. my API end points can only allow 100 call per request.
I have tried array chunking the list into "$sms" which seams to work well when I print_r($sms), but when echo the response, it returns only 48/249 responses regardless of the size specified in the array_chunk function. My question is, is there a better option to achieve this, something like array_chunking the mysqli results instead of the array list?
$query_sch = "SELECT * FROM ct_queue";
$sch_result = mysqli_query($mysqli, $query_sch);
$rows[] = mysqli_fetch_array($sch_result);
$count = mysqli_num_rows($sch_result);
foreach($sch_result as $value)
{
$phone = $value['phone'];
$sender = $value['sender'];
$message = $value['message'];
$user_id = $value['user_id'];
$link_id = NULL;
$correlator = 'correlator_string';
$endpoint = 'example.com';
$token = "token_string";
// $list = array();
$version = "v1"; //DONT change unless you are using a different version
$instance = new BonTech($token, $version);
$list[] = new Sms($sender, $phone, $message, $correlator, null, $endpoint);
}
$row_chunks = array_chunk($list, 100);
foreach ($row_chunks as $chunk){
$sms = array();
////////here we have 100 messages on each chunk
///////Loop through the messages in side the chunk
foreach ($chunk as $row) {
$sms[] = ($row);
}
// print_r($sms);
}
$response = call_user_func_array(array($instance, "sendBatchSMS"), $sms);
$response = json_encode($response, true);
$results = json_decode($response, true);
print_r($response);
You're using $sms after the foreach loop is done. So it will only contain the last chunk. You need to use it inside the loop.
There's also no need to use a loop to copy $chunk to $sms.
You're also skipping the first row of results because of your call to mysqli_fetch_array($sch_result) before the first foreach loop.
$instance doesn't seem to be dependent on $value, so it shouldn't be in the foreach loop.
$query_sch = "SELECT * FROM ct_queue";
$sch_result = mysqli_query($mysqli, $query_sch);
$list = array();
foreach($sch_result as $value)
{
$phone = $value['phone'];
$sender = $value['sender'];
$message = $value['message'];
$user_id = $value['user_id'];
$link_id = NULL;
$correlator = 'correlator_string';
$endpoint = 'example.com';
$list[] = new Sms($sender, $phone, $message, $correlator, null, $endpoint);
}
$token = "token_string";
$version = "v1"; //DONT change unless you are using a different version
$instance = new BonTech($token, $version);
$row_chunks = array_chunk($list, 100);
foreach ($row_chunks as $sms){
$response = call_user_func_array(array($instance, "sendBatchSMS"), $sms);
print_r($response);
}

How I coul get a JSON like this?

I need to get a JSON with arrays, how I could do it?
//JSON I need to get
{"keywords":[{"keyword":"kw1", "tags":["sample"]},{"keyword":"kw2", "tags":["sample, sample2"]}]}
//For now, I got this
$keywords = array("kw1", "kw2");
$tags= array("sample", "sample2");
function Keywords($keywords, $tags){
$fields= array("keywords" => $keywords);
$jsondata = json_encode($fields);
print_r($jsondata );
}
//output
{"keywords":["kw1","kw2"]}
I expect the output like this:
{"keywords":[{"keyword":"kw1", "tags":["sample"]},{"keyword":"kw2", "tags":["sample, sample2"]}]}
Assuming tags in the first element of your example is supposed to be ["sample, sample2"] as well (otherwise you would really have to explain by what logic you want to achieve at the result as shown) …
$keywords = array("kw1", "kw2");
$tags= array("sample", "sample2");
$result = new StdClass;
$result->keywords = [];
foreach($keywords as $keyword) {
$temp = new StdClass;
$temp->keyword = $keyword;
$temp->tags = [];
foreach($tags as $tag) {
$temp->tags[] = $tag;
}
$result->keywords[] = $temp;
}
echo json_encode($result);
Basically two nested loops over the keywords and the tags, and inside a new temporary object is created an then appended to the result array.

PHP Array & XML Can't get all content

I'm tring to get all content from this xml: https://api.eveonline.com/eve/SkillTree.xml.aspx
To save it on a MySQL DB.
But there are some data missing...
Could any1 that understand PHP, Array() and XML help me, please?
This is my code to get the content:
<?php
$filename = 'https://api.eveonline.com/eve/SkillTree.xml.aspx';
$xmlbalance = simplexml_load_file($filename);
$skills = array();
for ($x=0;$x<sizeOf($xmlbalance->result->rowset->row);$x++) {
$groupName = $xmlbalance->result->rowset->row[$x]->attributes()->groupName;
$groupID = $xmlbalance->result->rowset->row[$x]->attributes()->groupID;
for ($y=0;$y<sizeOf($xmlbalance->result->rowset->row[$x]->rowset->row);$y++) {
$skills[$x]["skillID"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->attributes()->typeID;
$skills[$x]["skillName"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->attributes()->typeName;
$skills[$x]["skillDesc"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->description;
$skills[$x]["skillRank"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rank;
$skills[$x]["skillPrimaryAtr"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->requiredAttributes->primaryAttribute;
$skills[$x]["skillSecondAtr"] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->requiredAttributes->secondaryAttribute;
$o = 0;
for ($z=0;$z<sizeOf($xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->row);$z++) {
if ($xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->attributes()->name == "requiredSkills") {
$skills[$x]["requiredSkills"]["".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->row[$z]->attributes()->typeID] = "".$xmlbalance->result->rowset->row[$x]->rowset->row[$y]->rowset->row[$z]->attributes()->skillLevel;
$o++;
}
}
}
}
echo '<pre>'; print_r($skills); echo '</pre>';
?>
If you go to the original XML (link), at line 452, you will see:
<row groupName="Spaceship Command" groupID="257">
And that isn't show in my array (link)...
That is one thing that i found that is missing...
I think that probally have more content that is missing too..
Why? How to fix it, please?
Thank you!!!
You will only get a total of sizeof($xmlbalance->result->rowset->row) records. Because, in your 2nd for loop, you are basically storing your result in the same array element that is $skills[$x].
Try this (I also higly encourage you to be as lazy as you can when you write code - by lazy I mean, avoid repeating / rewriting the same code over and over if possible) :
$filename = 'https://api.eveonline.com/eve/SkillTree.xml.aspx';
$xmlbalance = simplexml_load_file($filename);
$skills = array();
foreach ($xmlbalance->result->rowset->row as $row)
{
$groupName = $row->attributes()->groupName;
$groupID = $row->attributes()->groupID;
foreach ($row->rowset->row as $subRow)
{
$skill['skillID'] = (string) $subRow->attributes()->typeID;
$skill['skillName'] = (string) $subRow->attributes()->typeName;
$skill['skillDesc'] = (string) $subRow->description;
$skill['skillRank'] = (string) $subRow->rank;
$skill['skillPrimaryAtr'] = (string) $subRow->requiredAttributes->primaryAttribute;
$skill['skillSecondAtr'] = (string) $subRow->requiredAttributes->secondaryAttribute;
foreach ($subRow->rowset as $subSubRowset)
{
if ($subSubRowset->attributes()->name == 'requiredSkills')
{
foreach ($subSubRowset->row as $requiredSkill)
{
$skill['requiredSkills'][(string) $requiredSkill->attributes()->typeID] = (string) $requiredSkill['skillLevel'];
}
}
}
$skills[] = $skill;
}
}
print_r($skills);

Fetch, Decode and Re-encode JSON

I am attempting to fetch JSON from Instagram according to a number of URL parameters, the JSON is then decoded and then the objects required are then encoded into my own JSON format. Whilst I know this sound a little ridiculous, it is what is required. My only issue here is that for some reason it does not encode each section of JSON, it will only work for one item. The code is as below.
<?php
function instagram($count=16){
$igtoken = $_GET['igtoken'];
$hashtag = $_GET['hashtag'];
$url = 'https://api.instagram.com/v1/tags/'.$hashtag.'/media/recent/?access_token='.$igtoken.'&count='.$count;
$jsonData = json_decode((file_get_contents($url)));
$jsonData = json_decode((file_get_contents($url)));
foreach ($jsonData->data as $key=>$value) {
$response = array();
$response["data"] = array();
$data = array();
$data["createdtime"] = $value->caption->created_time;
$data["username"] = $value->caption->from->username;
$data["profileimage"] = $value->caption->from->profile_picture;
$data["caption"] = $value->caption->text;
$data["postimage"] = $value->images->standard_resolution->url;
array_push($response["data"], $data);
$result = json_encode($response);
}
return $result;
}
echo instagram();
?>
It will work for each section of JSON if I do something like this instead:
$result .= '<li>
'.$value->caption->from->username.'<br/>
'.$value->caption->from->profile_picture.'<br/>
'.$value->caption->text.'<br/>
'.$value->images->standard_resolution->url.'<br/>
'.$value->caption->created_time.'<br/>
</li>';
I feel I have bodged up somewhere with the array, however i'm not entirely sure.
What if we move $response["data"] and $result varia out of foreach?
Have you tried this?
$response = array();
$response["data"] = array();
foreach ($jsonData->data as $key=>$value) {
$data = array();
$data["createdtime"] = $value->caption->created_time;
$data["username"] = $value->caption->from->username;
$data["profileimage"] = $value->caption->from->profile_picture;
$data["caption"] = $value->caption->text;
$data["postimage"] = $value->images->standard_resolution->url;
array_push($response["data"], $data);
}
$result = json_encode($response);
return $result;

Structure of php JSON output

this is continued from another question i asked:
Listing out JSON data?
my search only returns 1 item, im pretty sure the problem lies somewhere in my php, im not too sure if im adding to the array properly, or it could be the javascript wich you can see on the above link, but i doubt it.
my php code:
function mytheme_ajax_response() {
$search = $_GET["search_text"];
$result = db_query("SELECT nid FROM {node} WHERE title LIKE '%s%' AND type = 'product_collection'", $search);
$noder = array();
while ($record = db_fetch_object($result)) {
$noder[] = $record;
}
$matches = array();
$i = 0;
foreach ($noder as $row) {
$node = node_load($row->nid);
$termlink = db_fetch_object(db_query("SELECT tid FROM {term_node} WHERE nid = %d", $row->nid));
$matches[$i]['title'] = $node->title;
$matches[$i]['link'] = $termlink->tid;
}
++$i;
$hits = array();
$hits['matches'] = $matches;
print json_encode($hits);
exit();
}
You appear to be incrementing your $i variable AFTER the foreach loop. Therefore, $i is always 0 throughout your loop, so you are always setting the title and link values for $matches[0].
Try this:
function mytheme_ajax_response() {
$search = $_GET["search_text"];
$result = db_query("SELECT nid FROM {node} WHERE title LIKE '%s%' AND type = 'product_collection'", $search);
$noder = array();
while ($record = db_fetch_object($result)) {
$noder[] = $record;
}
$matches = array();
foreach ($noder as $row) {
$node = node_load($row->nid);
$termlink = db_fetch_object(db_query("SELECT tid FROM {term_node} WHERE nid = %d", $row->nid));
$matches[] = array('title' => $node->title, 'link' => $termlink->tid);
}
$hits = array();
$hits['matches'] = $matches;
print json_encode($hits);
exit();
}
The $i wasn't incrementing the code as it was outside the foreach loop. By making a second array as above you don't need it anyway... (hope this works)...
