PHP curl Response string splitting - php

Question

So here is the issue. I am pulling a CSV file from an API and need to place it into an array. Here is my current code:
$url = "https://www.*****************";
$myvars = 'username=*********&password=*************';
$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS, $myvars);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
//curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text'));
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if(!curl_exec($ch)){
die('Error: "' . curl_error($ch) . '" - Code: ' . curl_errno($ch));
} else {
$response = curl_exec($ch);
$exploded = nl2br($response);
//echo $response."<br>";
var_dump($exploded);
}
curl_close($ch);
The problem is I am getting the response:
string(245) ""Number","Name","Description","Type","Fixed Width Boolean","Quote Character","Delimiter Character","End of Line Sequence","Header Boolean","Column Count"
"1","All Calls","All Call Data","Call","false","None",",","\r\n","true","14"
"
This is two lines in the CSV, but comes out in a single string line. I tried exploding it, but it seems to have two delimiters and I tried splitting it, but it will not find the second delimiter. I want it to generate like this:
array(
"Number" => 1,
"Name" => "All Calls",
"Description" => "All Call Data",
"Type" => "Call",
"Fixed Width Boolean" => false,
"Quote Character" => "None",
"Delimiter Character" => ",",
"End of Line Sequence" => "\r\n",
"Header Boolean" => true,
"Column Count" => 14
);
The first line of the CSV is the headers and the data underneath is the data it needs to align to. Also future requests will have multiple lines of data and they need to match with the headers too. Any ideas?

If you're dealing with CSV, try using the built-in function for such. Then use array_combine to stick your headers in as keys:
$response = curl_exec($ch);
$csv_data = array_map('str_getcsv', explode("\n", $response));
$headers = array_shift($csv_data);
foreach ($csv_data as $v) {
$data[] = array_combine($headers, $v);
}
As an example:
$response = <<< CSV
"Number","Name","Description","Type","Fixed Width Boolean","Quote Character","Delimiter Character","End of Line Sequence","Header Boolean","Column Count"
"1","All Calls","All Call Data","Call","false","None",",","\\r\\n","true","14"
CSV;
$csv_data = array_map('str_getcsv', explode("\n", $response));
$headers = array_shift($csv_data);
foreach ($csv_data as $v) {
$data[] = array_combine($headers, $v);
}
print_r($data);
Output:
Array
(
[0] => Array
(
[Number] => 1
[Name] => All Calls
[Description] => All Call Data
[Type] => Call
[Fixed Width Boolean] => false
[Quote Character] => None
[Delimiter Character] => ,
[End of Line Sequence] => \r\n
[Header Boolean] => true
[Column Count] => 14
)
)

You can also turn your csv string into a file pointer and use fgetcsv on it. Here is an example of how it works:
Josh:~$ php -a
Interactive shell
php > $data = <<<CSV
<<< > "col1","col2"
<<< > "d1",","
<<< > CSV;
php > echo $data;
"col1","col2"
"d1",","
php > $fp = fopen('data://text/plain,' . $data, 'r');
php > while (($row = fgetcsv($fp)) !== false) {
php { var_dump($row);
php { }
array(2) {
[0]=>
string(4) "col1"
[1]=>
string(4) "col2"
}
array(2) {
[0]=>
string(2) "d1"
[1]=>
string(1) ","
}
Using your example it would be similar to the following
$response = <<<CSV
"Number","Name","Description","Type","Fixed Width Boolean","Quote Character","Delimiter Character","End of Line Sequence","Header Boolean","Column Count"
"1","All Calls","All Call Data","Call","false","None",",","\r\n","true","14"
CSV;
$fp = fopen('data://text/plain,' . $response, 'r');
$data = [];
$header = fgetcsv($fp); // first row is column headers
while (($row = fgetcsv($fp)) !== false) {
$data[] = array_combine($header, $row);
}
print_r($data); // list of rows with keys set to column names from $header
/*
Array
(
[0] => Array
(
[Number] => 1
[Name] => All Calls
[Description] => All Call Data
[Type] => Call
[Fixed Width Boolean] => false
[Quote Character] => None
[Delimiter Character] => ,
[End of Line Sequence] =>
[Header Boolean] => true
[Column Count] => 14
)
)
*/

Well, this is a bit "hacky" but it works....
PHP Fiddle
$response = '"Number","Name","Description","Type","Fixed Width Boolean","Quote Character","Delimiter Character","End of Line Sequence","Header Boolean","Column Count","1","All Calls","All Call Data","Call","false","None",",","\r\n","true","14"';
$response = preg_replace('/[,]/', "*", $response);
$response = str_replace('*"*"*', '*","*', $response);
$exploded = explode("*", $response);
$count = count($exploded)/2;
$newArray = [];
for($i=0; $i<$count; ++$i){
$newArray[$exploded[$i]] = $exploded[$i+$count];
}
print_r($newArray);
Which prints
Array
(
["Number"] => "1"
["Name"] => "All Calls"
["Description"] => "All Call Data"
["Type"] => "Call"
["Fixed Width Boolean"] => "false"
["Quote Character"] => "None"
["Delimiter Character"] => ","
["End of Line Sequence"] => "\r\n"
["Header Boolean"] => "true"
["Column Count"] => "14"
)
