Php Json_encode issue

[joshmrtin9]

I have a database created with data im trying to retreive via php and then encode into json for an iphone/andriod application.

The connection to my database works fine and i am able to retreive data and "encode" it so it seems. The format however is not correct. I can manually tweek the result and view the data on the phone like i need to but maybe someone can point out what im overlooking.

 

Here is the code i am working with:

 

$sql = "SELECT * FROM BUSA";
$results = sqlsrv_query($conn, $sql);
if (sqlsrv_has_rows($results)) {
while ($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
{
echo json_encode($row);
}
 
} else {
echo "No Results were Found";
}
 
/* Close the connection. */
sqlsrv_close( $conn);

 

As i said i do get results from this and it looks like this:

{"Jersey_Number":"12 ","Position":" ","Name":" 01. Brannon, Melanie ","Games_Played":" 10 ","Goals":" - ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"91 ","Position":" ","Name":" 02. Campbell, Claudia ","Games_Played":" 2 ","Goals":" - ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"15 ","Position":" ","Name":" 03. Carpenter, Alyssa ","Games_Played":" 2 ","Goals":" - ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"76 ","Position":" ","Name":" 04. Casey, Amy ","Games_Played":" 17 ","Goals":" - ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"14 ","Position":" F ","Name":" 05. Degenaar, Lia ","Games_Played":" 5 ","Goals":" - ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"25 ","Position":" M ","Name":" 06. Dumas, Natalie ","Games_Played":" 17 ","Goals":" - ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"7 ","Position":" ","Name":" 07. Eubanks, Anna ","Games_Played":" 11 ","Goals":" 2 ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"28 ","Position":" ","Name":" 08. Greene, Jasmine ","Games_Played":" 2 ","Goals":" 2 ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"3 ","Position":" F ","Name":" 09. Hamilton, August ","Games_Played":" 17 ","Goals":" 3 ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}
{"Jersey_Number":"17 ","Position":" ","Name":" 10. Hoaglund, Lauren ","Games_Played":" 17 ","Goals":" - ","Assists":" - ","Yellow_Cards":" - ","Red_Cards":" -"}

 

Now where i'm having the issue is this encodes each query as individual objects but there is no comma seperation between objects. So what i did to manually make this work was place commas between all objects and then [ results.. ] place all the results in bracket to make it an array of objects. Any suggestions would be greatley appreciated!

The reason why you get each array encoded individually is because that's exactly what you've told PHP to do: You have a loop, and in this loop, you encode and echo each $row.

 

If you want to collect all rows in an array and then encode the whole thing, well, do that.

Thanks, i knew it was a rather trivial question.

 

Fixed it with this:

 

$sql = "SELECT * FROM BUSA";
$results = sqlsrv_query($conn, $sql);
if (sqlsrv_has_rows($results)) {
while ($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
$roster[] = $row;
{
echo json_encode($roster);
}

} else {
echo "No Results were Found";
}

/* Close the connection. */
sqlsrv_close( $conn);

[Jacques1]

What are those weird braces after the $roster[] = $row supposed to do?

[joshmrtin9]

That put all my results from $row into one big array. When i run my code using the above fix i get these results from my json_encode.

This being the correct format i need in order to display my results on the application.

[Jacques1]

I'm talking about the braces right after the $roster[] = $row. They don't do anything, because they're not attached to any control structure. Remove them.

[joshmrtin9]

They are certainly doing something it seems.

I removed them and this is now my results:

 

{"Jersey_Number":"19 ","Position":" ","Name":" 24. Young, Alyssa ","Games_Played":" 15 ","Goals":" 3 ","Assists":" 1 ","Yellow_Cards":" - ","Red_Cards":" -"}

 

 

 

I only get 1 query in return and this one is not in the correct format as it is when i have $roster[] = $row

[bsmither]

May I suggest:

WAS:
while ($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
$roster[] = $row;
{
echo json_encode($roster);
}
 
Now:
while ($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
{
$roster[] = $row;
}
echo json_encode($roster);

[Jacques1]

Or simply

while ($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
	$roster[] = $row;

echo json_encode($roster);

[joshmrtin9]

Thanks for all the help i have it generating the correct output.

[QuickOldCar]

 

Or simply

while ($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
	$roster[] = $row;

echo json_encode($roster);

 

I like bsmither's way with curly braces, helps keep coding consistent and never forget them when needed.

My opinion of course.

 

 

 

while ($row = sqlsrv_fetch_array($results, SQLSRV_FETCH_ASSOC))
{
$roster[] = $row;
}
echo json_encode($roster);
