How do you display the output of a 2 dimensional arrays
Here's the code:
I know how to display both of them separately doing.
foreach($Father as $value){
echo $value[0] . " " . $value[1] . "<br />";
}
foreach($Son as $value){
echo $value[0] . " " . $value[1] . "<br />";
}
try this - it assumes that each father has exactly 1 son though
$i = 0;
foreach($Father as $value){
echo $value[0] . " " . $value[1] . "<br />";
echo "-" . $Son[$i][0] . " " . $Son[$i][1] . "<br />";
$i += 1;
}

I've made a foreach loop that print some variables found in an xml file:
foreach ($xml->result->rowset->row as $row)
{
echo $row["price"] . " " . $row["product"] . "</br>";
}
I would like to get the sum of all the "prices" shown. How can i do?
Just have a variable add up those values as you iterate:
$total = 0; // start with zero
foreach ($xml->result->rowset->row as $row)
{
$total += $row["price"]; // add price to total
echo $row["price"] . " " . $row["product"] . "</br>";
}
echo $total; // echo out total amount
Store the count in a variable:
$total = 0;
foreach ($xml->result->rowset->row as $row) {
echo $row["price"] . " " . $row["product"] . "</br>";
$total += $row['price']; // assumed row_price is some integer
}
echo $total;
Simply add it to a new variable:
$sum = 0;
foreach ($xml->result->rowset->row as $row) {
echo $row["price"] . " " . $row["product"] . "<br />";
$sum += $row["price"];
}
echo $sum . "<br />";
$sum = 0;
foreach ($xml->result->rowset->row as $row)
{
echo $row["price"] . " " . $row["product"] . "</br>";
$sum += $row["price"] ;
}
echo $sum ;
isnt that simple ?
$sum=0;
foreach ($xml->result->rowset->row as $row)
{
echo $row["price"] . " " . $row["product"] . "</br>";
$sum +=$row["price"];
}
echo $sum;
just try this code!!
I am getting the result from the SOAP client as an response. I just have to analyze the structure of the parameter and display the results accordingly. I have the following srucutre for SerialEquipment and i am getting the results peoperly for all the parameters except the Esaco parameter. The Esaco parameter is an array object and it resides inside the SerialEquipment array. I am trying to fetch the response from Esaco array object but getting an error as Invalid arguments supplied for foreach. I am not understanding how to get the results for Esaco Parameter by looping properly.Just a small mistake i am doing in looping the array.
Code:
foreach($Serial as $key => $obj)
{
echo "<b>"."Serial Equipment=>" . $key . "</b>"."<br>";
echo "Code=>". $obj->Code . "<br>";
echo "Desc Short=>". $obj->Desc_Short . "<br>";
echo "Desc Long=>". $obj->Desc_Long . "<br>";
foreach($obj->Esaco as $key2 => $obj2)
{
if($obj2 === null){
// doesn't contain Esaco
break;
}
else{
echo "<b>"."Esaco=>" . $key2 . "</b>"."<br>";
echo "EsacoMainGroupCode=>". $obj2->EsacoMainGroupCode . "<br>";
echo "EsacoMainGroupDesc=>". $obj2->EsacoMainGroupDesc . "<br>";
echo "EsacoSubGroupCode=>". $obj2->EsacoSubGroupCode . "<br>";
echo "EsacoSubGroupCode=>". $obj2->EsacoSubGroupDesc . "<br>";
echo "EsacoSubGroupCode=>". $obj2->EsacoGroupCode . "<br>";
echo "EsacoSubGroupCode=>". $obj2->EsacoGroupDesc . "<br>";
}
}
}
if($parameter['aktion'] == 'getVehicle')
{
$vehicle = getVehicleValuation();
$Serial=$vehicle['SerialEquipment'];
$VehicleFuel=$vehicle['VehicleFuel'];
foreach($VehicleFuel as $key => $obj2)
{
echo "Fuel Type=>". $obj2->Fuel_Type . "<br>";
echo "Fuel Type Code=>". $obj2->Fuel_Type_Code . "<br>";
echo "ECE_Unit=>". $obj2->ECE_Unit . "<br>";
echo "ECE_In=>". $obj2->ECE_In . "<br>";
echo "ECE_Out=>". $obj2->ECE_Out . "<br>";
echo "ECE_All=>". $obj2->ECE_All . "<br>";
echo "ECE_CO2=>". $obj2->ECE_CO2 . "<br>";
}
}
This is my structure for SerialEquipment:
if($parameter['aktion'] == 'getVehicle')
{
$vehicle = getVehicleValuation();
if(($serials = $vehicle['SerialEquipment']) === null){
// doesn't contain SerialEquipment
break;
}
foreach($serials as $serial){
print "Code =>" . $serial->Code . "<br>";
print "Desc Short =>" . $serial->Desc_Short . "<br>";
//...
foreach($serial->Esaco as $esaco){
print "EsacoMainGroupCode =>" . $esaco->EsacoMainGroupCode. "<br>";
print "EsacoMainGroupDesc =>" . $esaco->EsacoMainGroupDesc. "<br>";
//...
}
}
}
And for the VehicleFuel:
if($parameter['aktion'] == 'getVehicle')
{
$vehicle = getVehicleValuation();
$Serial=$vehicle['SerialEquipment'];
$VehicleFuel=$vehicle['VehicleFuel'];
$fuelType = $VehicleFuel->Fuel_Type;
// if there is only going to be one VehicleFuel object Vehicle, then just do..
echo "Fuel Type =>". fuelType->Fuel_Type . "<br>";
echo "Fuel Type Code =>". $fuelType->Fuel_Type_Code . "<br>";
// if there will be more than one, you will want to use a loop...
foreach($fuelType as $obj)
{
echo "Fuel Type=>". $obj->Fuel_Type . "<br>";
echo "Fuel Type Code=>". $obj->Fuel_Type_Code . "<br>";
echo "ECE_Unit=>". $obj->ECE_Unit . "<br>";
echo "ECE_In=>". $obj->ECE_In . "<br>";
echo "ECE_Out=>". $obj->ECE_Out . "<br>";
echo "ECE_All=>". $obj->ECE_All . "<br>";
echo "ECE_CO2=>". $obj->ECE_CO2 . "<br>";
}
}
The key Esaco is an object not an array. You should change your second foreach.
foreach($Serial as $key => $obj) {
echo "Serial Equipment=>" . $key . "<br>";
echo "Code=>". $obj->Code . "<br>";
echo "Desc Short=>". $obj->Desc_Short . "<br>";
echo "Desc Long=>". $obj->Desc_Long . "<br>";
foreach($obj->Esaco as $key2 => $obj2) {
echo $obj2;
//...
}
}
I'm trying to show a list of all nearby weather stations.
I have the code:
$json_string = file_get_contents("http://api.wunderground.com/api/8b19ccf6a06c0826/geolookup/conditions/q/Netherlands/Rotterdam.json");
$parsed_json = json_decode($json_string);
$stations = $parsed_json->{'location'}->{'nearby_weather_stations'}->{'pws'}->{'station'};
$count = count($stations);
for($i = 0; $i < $count; $i++)
{
$station = $stations[$i];
if (count($station) > 1)
{
echo "City: " . $station->{'city'} . "\n";
echo "State: " . $station->{'state'} . "\n";
echo "Latitude: " . $station->{'lat'} . "\n";
echo "Longitude: " . $station->{'lon'} . "\n";
}
}
But currently it's not showing anything, i have searched for examples but i couldn't find any solution fot this problem.
Alternatively, you could use a simple foreach to iterate those values. Consider this example:
$json_string = file_get_contents("http://api.wunderground.com/api/8b19ccf6a06c0826/geolookup/conditions/q/Netherlands/Rotterdam.json");
$parsed_json = json_decode($json_string, true); // <-- second parameter to TRUE to use it as an array
$desired_values = $parsed_json['location']['nearby_weather_stations']['pws']['station'];
foreach($desired_values as $key => $value) {
echo "<hr/>";
echo "City: " . $value['city'] . "<br/>";
echo "State: " . $value['state'] . "<br/>";
echo "Latitude: " . $value['lat'] . "<br/>";
echo "Longitude: " . $value['lon'] . "<br/>";
echo "<hr/>";
}
Sample Fiddle
I am working on my first program written in PHP. This is a basic question. I am trying to print a string stored in an array. I have two arrays. One array, $content, stores a number at $content[$i][15] (i am using arrays in arrays, and looping through it with a for loop). Lets say this number is 3. I now want to access a string in another array, called $type. This string is at position $type[3]. Logically, I think, $type[3] should print the same thing as $type[$content[$i][15]]. But, when I call $type[$content[$i][15]], it doesn't print anything, but when i print $type[3] it works fine. Is this type of call not allowed in PHP?
$type = array();
$typetemp = readfile("type.csv");
foreach ($typetemp as $sa){
$type[$sa[0]] = $sa[1];
}
$content = readfile("content.csv");
for($i=0; $i<sizeof($content); $i++){
if($content[$i][15] == 3){
if($content[$i][4] == 1){
$temp = $content[$i][15];
echo "id is " . $content[$i][0] . "title is " . $content[$i][1] . "introtext is " . $content[$i][2] . "restoftext is " . $content[$i][3] . "visible is " . $content[$i][4] . "category is " . $content[$i][5] . "creation_date is " . $content[$i][6] . "author is " . $content[$i][7] . "img is " . $content[$i][8] . "ordering is " . $content[$i][9] . "rank is " . $content[$i][10] . "vid is " . $content[$i][11] . "start_date is " . $content[$i][12] . "stop_date is " . $content[$i][13] . "event_date is " . $content[$i][14] . "type is " . $content[$i][15] . "thumb is " . $content[$i][16] . "type name is " . $type[$temp] . "<br/>";
}
}
}
function readfile($filename) {
$line_of_text = array();
$file_handle = fopen($filename, "r");
while (!feof($file_handle) ) {
array_push($line_of_text, fgetcsv($file_handle, 1024));
}
fclose($file_handle);
return $line_of_text;
}
You are missing a $ sign before content:
$type[$content[$i][15]]
This accesses the value in $type with index $content[$i][15]
This is supposed to return raw values for Rx and Tx for each adapter (output is in pairs) ONLY of the adapter has transferred more than zero data.
<?php
//windows network usage testing
function win_netinfo(){
ob_start();
$wmi = new COM("Winmgmts://");
$nets = $wmi->execquery("SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface WHERE BytesSentPersec > 1");
foreach ($nets as $net)
{
$net_txbytes = $net->BytesSentPersec;
$net_rxbytes = $net->BytesReceivedPersec;
if ($net_txbytes < 0) {
$net_txbytes = $net->BytesTotalPersec - $net->BytesReceivedPersec;
}
if ($net_rxbytes < 0) {
$net_rxbytes = $net->BytesTotalPersec - $net->BytesSentPersec;
}
return $net_txbytes . "</br>"; //When it RETURNS it only shows the FIRST value... :/ WHAT DO?
}
}
echo win_netinfo();
?>
Output should be like this:
21936313136
12345163517
13647613
87653467
546254
246247
87653642
24583462
(Every other line is Rx or Tx, for each adapter).
Current code that works:
<?php
# Peport All Errors
error_reporting(E_ALL);
# Create Object
$wmi = new COM("Winmgmts://");
# Get net info
$oss = $wmi->execquery("SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface");
# Show net info
foreach($oss as $os)
{
echo "BytesReceivedPerSec: " . $os->BytesReceivedPerSec . "<br />";
echo "BytesSentPerSec: " . $os->BytesSentPerSec . "<br />";
echo "BytesTotalPerSec: " . $os->BytesTotalPerSec . "<br />";
echo "Caption: " . $os->Caption . "<br />";
echo "CurrentBandwidth: " . $os->CurrentBandwidth . "<br />";
echo "Description: " . $os->Description . "<br />";
echo "Frequency_Object: " . $os->Frequency_Object . " kb<br />";
echo "Frequency_PerfTime: " . $os->Frequency_PerfTime . "<br />";
echo "Frequency_Sys100NS: " . $os->Frequency_Sys100NS . "<br />";
echo "Name: " . $os->Name . "<br />";
echo "OutputQueueLength: " . $os->OutputQueueLength . "<br />";
echo "PacketsOutboundDiscarded: " . $os->PacketsOutboundDiscarded . "<br />";
echo "PacketsOutboundErrors: " . $os->PacketsOutboundErrors . "<br />";
echo "PacketsReceivedNonUnicastPerSec: " . $os->PacketsReceivedNonUnicastPerSec . "<br />";
echo "PacketsReceivedPerSec: " . $os->PacketsReceivedPerSec . "<br />";
echo "PacketsReceivedUnicastPerSec: " . $os->PacketsReceivedUnicastPerSec . "<br />";
echo "PacketsReceivedUnknown: " . $os->PacketsReceivedUnknown . "<br />";
echo "PacketsSentNonUnicastPerSec: " . $os->PacketsSentNonUnicastPerSec . "<br />";
echo "PacketsSentPerSec: " . $os->PacketsSentPerSec . "<br />";
echo "PacketsSentUnicastPerSec: " . $os->PacketsSentUnicastPerSec . "<br />";
echo "Timestamp_Object: " . $os->Timestamp_Object . "<br />";
echo "Timestamp_PerfTime: " . $os->Timestamp_PerfTime . "<br />";
echo "Timestamp_Sys100NS: " . $os->Timestamp_Sys100NS . "<br />";
echo "<br /><br /><br />";
}
?>
Your returning after the first iteration hence only 1 result, below is how i would do it by creating an array and returning that instead:
<?php
//windows network usage testing
function win_netinfo(){
$wmi = new COM("Winmgmts://");
$nets = $wmi->execquery("SELECT * FROM Win32_PerfRawData_Tcpip_NetworkInterface WHERE BytesSentPersec > 1");
$return=array();
$i=0;
foreach ($nets as $net){
$return[$i]['name']=$net->Name;
if ($net->BytesSentPersec < 0) {
$return[$i]['net_txbytes'] = $net->BytesTotalPersec - $net->BytesReceivedPersec;
}else{
$return[$i]['net_txbytes'] = $net->BytesSentPersec;
}
if ($net->BytesReceivedPersec < 0) {
$return[$i]['net_rxbytes'] = $net->BytesTotalPersec - $net->BytesSentPersec;
}else{
$return[$i]['net_rxbytes'] = $net->BytesReceivedPersec;
}
$i++;
}
return $return;
}
$adapters=win_netinfo();
/*Array
Array
(
[0] => Array
(
[name] => VirtualBox Host-Only Ethernet Adapter
[net_txbytes] => 5095956
[net_rxbytes] => 0
)
[1] => Array
(
[name] => Belkin 54g Wireless USB Network Adapter
[net_txbytes] => 532337967
[net_rxbytes] => 5252455518
)
)
*/
?>
And to output the array, something like this:
<?php
foreach($adapters as $adapter){
echo '<p>'.$adapter['name'].' - Sent: '.$adapter['net_txbytes'].' bytes - Received: '.$adapter['net_rxbytes'].' bytes</p>';
}
?>
