PHP - Creating A Rest Api

Specific question with general application here. i am having some trouble with a loop and am getting some odd timing results
specifically this is a WMI query on a hyper-v server retrieving disk information but im not sure the context of the query is relevant here. The main question is how come the first iteration of the loop is so much slower than the other iterations, it just doesnt seem to make sense to me unless ive done something stupid here i cannot see.  any ideas ?

Code: [Select]
<?php
$diskstart = microtime(true);
// get the hard disk size 
try {
$resultDisk = $wmi->ExecQuery("SELECT BlockSize,NumberOfBlocks FROM msvm_LogicalDisk where systemname like '%" . $guid . "%' and name='Hard Disk Image'");
$ct=0;
$start1 = microtime(true);
$start = microtime(true);
foreach($resultDisk as $itemDisk) {
$end = microtime(true);
echo "<BR>FOREACH: [" . Round($end-$start,3) . "] seconds";
$vm[$name]['disks'][$ct] = ($itemDisk->BlockSize * $itemDisk->NumberOfBlocks)/1024;  // format the disk size into KB
$ct++;
$start = microtime(true);
}
$end1 = microtime(true);
echo "<br>      ALLLOOP: [" . Round($end1-$start1,3) . "] ";
}
catch(exception $e) {
}
$diskend = microtime(true);
echo "<br>DISK: [" . ($diskend-$diskstart) . "] seconds";
?>


and here are the results
Code: [Select]
FOREACH: [1.236] seconds

Hi,

I am using the Google map API to display some businesses on a map - the sequence is map and below it a list of the establishments from a DB.

Before I put the google map in, the list of establishments in the while table loop worked correctly.

Now the map is there - that works, but the looping table doesnt display - I feel that it may be something to do with Code: [Select]
<?php while ($row = mysql_fetch_array($result2, MYSQL_ASSOC))
    { ?>
    new google.maps.LatLng(<? echo $row['latitude'] ?>, <? echo $row['longitude']?>),

 <?php  ; }  ?> and the second fetch array - Code: [Select]
while ($row = mysql_fetch_array($result2, MYSQL_ASSOC))
Any Advice?


Code: [Select]
<?php


// *******************************below is  bit that selects hotels based on outcode of postcode and prints table with links to details pages

$sql2 = "SELECT * FROM hotels WHERE (SUBSTRING_INDEX(est_postcode, ' ', 1))   IN ('$matches') ";

$result2 = mysql_query($sql2) or die('query failed: ' . mysql_error());
 $num_rows = mysql_num_rows($result2);
 echo "<p> Your search has found ".$num_rows . " establishment(s) </p>";

 ?>

 ];

    };

            mapOptions);
  }

  function drop() {
    for (var i = 0; i < neighborhoods.length; i++) {
      setTimeout(function() {
        addMarker();
      }, i * 200);
    }
  }

Hi,

I have used the following script to consume REST webservices  provided by Commission Junction. I'm able to get the response but the response is not in xml format.
<?php

$targeturl="https://support-services.api.cj.com/v2/countries";
 
$CJ_DevKey= "xxxxxxxxx";

// return xml feed from CJ

$ch = curl_init($targeturl);
curl_setopt($ch, CURLOPT_POST, FAlSE);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: '.$CJ_DevKey));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
curl_close($ch);

echo $response; // will print in browser all country codes in an xml format

/*

ADD YOUR OWN CODE HERE TO DO WHAT YOU WANT WITH THE RESPONSE.  MAYBE SAVE RESULTS TO A FILE OR THE PARSE THE RESULTS INTO A DATABASE?

*/

?>
I'm just confused. Isn't that the response when using REST webservices is always in xml format. Please correct me if I'm wrong.

Would someone please have a look at this script and suggest me what I need to do in order to get the response in xml ? I want to save the response in xml file and then process it later.

please see my current sample output here. www(dot)uedeals(dot)com/cj/cj3.php

Do you use the OS userids or do you keep them separate in MYSQL? Must users login to a website and request a token to use for REST API requests? Did you use a framework provided method? I need something ultra-simple

I have the following tables:

department id course id department_id CASCADE DELETE student id student_courses course_id CASCADE DELETE student_id CASCADE DELETE

I also have the following REST API endpoints:

DELETE department/123 (deletes targeted department and associated courses as well as the list of students in the course) DELETE course/321 (deletes targeted course as well as the list of students in the course) DELETE student/111 (deletes targeted student as well as the list of students in the course)

The user should be informed before deleting a given record if that record will affect other tables.  For instance, if deleting a department which has some courses or deleting a student which belows to a course.

One option is to respond to DELETE department/123 with 400 {recordUsed: {courses:[bla, bla], student_courses:[bla, bla]}} if used.  For this option, the client would then prompt the user of the implications and if desired repeat the request but include a "force" parameter of TRUE in the request which will delete the record regardless of being used.

Another option is to add some new endpoints which will return the resources which are associated with the to be deleted entity.  If empty, a DELETE request would automatically be made and if not empty the user will first be prompted whether the DELETE request should be made and the server would delete the record(s) regardless of being used.

GET department/utilized/123 GET course/utilized/321 GET student/utilized/111

Any thoughts on which approach should be used?  Or maybe some other strategy?  Thanks

I implemented an endpoint which receives name/value pairs:

PUT someresource/123 {"name": "description", "value": "Some new description"}

I think I made a mistake, and should have implemented it as:

PUT someresource/123 {"description": "Some new description"}

The reason I think so is updating multiple properties is only (easily) possible using the later:

PUT someresource/123 {"description": "Some new description", "otherProperty": "bla bla bla"}

Assuming I am not using some 3rd party client library which only works with name/value pairs, any compelling reason why one shouldn't default to the later approach with key/values?

I actually have two parts to this post.  One which describes just my understanding on how a multipart request should look with a REST API and gives a little context, and the second how to actually implement it using Sympony and api-platform.

Part 1

Looking to simultaneously upload a file, some file meta data, and identifier of the uploading user to a REST API, and will do so using a multipart request.

Based on swagger, looks like the request should look something like the following:

POST /upload HTTP/1.1
Content-Length: 428
Content-Type: multipart/form-data; boundary=abcde12345
--abcde12345
Content-Disposition: form-data; name="id"
Content-Type: text/plain
123e4567-e89b-12d3-a456-426655440000
--abcde12345
Content-Disposition: form-data; name="address"
Content-Type: application/json
{
  "street": "3, Garden St",
  "city": "Hillsbery, UT"
}
--abcde12345
Content-Disposition: form-data; name="profileImage "; filename="image1.png"
Content-Type: application/octet-stream
{…file content…}
--abcde12345--

Background noise... The above example shows three parts which include the text ID, JSON address and octet-stream file.  Doing so doesn't make sense to me and I will probably just have two parts for the meta data JSON.  Note that potentially, I will be removing the user from the JSON payload and including it in some JWT header.  Also, showing resources as links such as /api/users/1 in the request and response JSON is new to me, but I guess makes sense.

Regardless, my meta data JSON will look like:

{
    "projectId": 1234,
    "documentDescription": "bla bla bla",
    "specification": "230903.2.4.D",
    "user": "/api/users/1"
}

and the response will look like:

{
    "projectId": 1234,
    "documentDescription": "bla bla bla",
    "specification": "230903.2.4.D",
    "uploadAt": "2021-01-27 08:41:17",
    "fileName": "pressuresensor.pdf".
    "user": "/api/users/1".
    "file": "/api/uplodaed_files/1234"
}

Am I somewhat going down the right path?

Part 2

Wow, should have looked into Sympony before now!  Entities, validation, the API, etc were a breeze.  Still confused with some of the "magic", but understanding what is under the hood more and more.

As stated initially, I am utilizing api-platform and am looking at api-platform's file-upload.

I guess the first question is whether my POST request with both the file and JSON meta data can be performed in a single request.

Per making-a-request-to-the-media_objects-endpoint:

Quote

Your /media_objects endpoint is now ready to receive a POST request with a file. This endpoint accepts standard multipart/form-data-encoded data, but not JSON data.

What?  Am I reading this correct?  Do I first need to make a multipart requests using either a standard HTML form or a XMLHttpRequest which just sends the file, receive the document locator, and then send a second request with the location and my meta data?

If so, I guess I have enough to go forward.  I would rather, however, perform the work in a single request.  My previous mentioned swagger multipart-requests shows both in the same request.  symfonycasts's api-uploads also describes doing so, but not with api-platform.  Is there a way to do so with api-platform?  Does it make sense to use api-platform for all other routes but then make a custom route for document with meta data uploads?  Any recommendations are much appreciated.

Thanks

So what i mean is if i set a variable to "[" ($some_variable = "[") the rest of my code is now going to go CRAZY because there is an open [. Is there a way I can just make everything inside the first set of "" not relevant to the code? thanks!

Dear Friends.

Just now I tried to create PHP to make Rest API for my mobile application and I would like to know that it's good coding and need any improve? it is my first time for Rest API. normally I just connect to PHP file directly

on .htaccess

    $error['detail'] = "Invalid Attribute For Information";

    echo json_encode($error);die();

$result = $conn->query("select Lab_Name,Lab_Username,Lab_Password from tb_labmanagers");
$customer = array();
while($row =mysqli_fetch_assoc($result))
{
    $customer[] = $row;
}

echo json_encode($customer);

this image attached file is result from postman, client need to send user = 'lung' to get information

Ok, I have one database three tables.

Table 1 is ncmr the main table where everything is to be entered.

Table 2 is companies, where all the companies in pull down menu 1 is located.

Table 3 is fabricators, where all the people who have had hands on the product are residing.

I want the selected choices of table 2 and 3 to be inputed into table 1. I know this has to be possible, but I don't know how.  I thought I wrote the code correctly, but it seems not.

Can someone review my code and show me where my mistake is?

Hello everyone,

I found a tutorial on creating a pdf with php and I just tried to create a basic pdf to see if it worked and modify it from there.  Here is the link to the tutorial: http://www.astahost.com/info/tfclt-create-pdf-php-create-fly-pdf-web-server.html

Well, after uploading the following php file to the server and testing it, I got this error:

Fatal error: Call to undefined function pdf_new() in /home/caresa6/public_html/BubblyBounce.com/admin/pdftest.php on line 2

Here's the code that produced the error:
Code: [Select]
<?php
$mypdf = PDF_new();
PDF_open_file($mypdf, "");
PDF_begin_page($mypdf, 595, 842);
$myfont = PDF_findfont($mypdf, "Times-Roman", "host", 0);
PDF_setfont($mypdf, $myfont, 10);
PDF_show_xy($mypdf, "Sample PDF, constructed by PHP in real-time.", 50, 750);
PDF_show_xy($mypdf, "Made with the PDF libraries for PHP.", 50, 730);
PDF_end_page($mypdf);
PDF_close($mypdf);

$mybuf = PDF_get_buffer($mypdf);
$mylen = strlen($mybuf);
header("Content-type: application/pdf");
header("Content-Length: $mylen");
header("Content-Disposition: inline; filename=gen01.pdf");
print $mybuf;

PDF_delete($mypdf);
?>

Can anyone help me figure out what to do from here?  I have some PHP knowledge, but I'm treading in uncharted waters with this, so I am totally lost.  Thanks in advance.

I want to create an image using pre-existing image files.  I want to use more than one file, otherwise I would use the imagecreatefromjpg function.  What function should I use to create an image using a for statement to determine how many of each image is being displayed in the new image?

I need help making the variable $code in sessions.php to work with the email activation.
