I just want to get a return of
Array (
[display_number] => 00001-Balter and Son
[display_number] => 00002-Seamless Solutions
)
Then take this and save this as a CSV
00001,Balter and Son,
00002,Seamless Solutions
Any help would be awesome.
I know there has to be an easy way to do this.
Someone asked for the PHP. Little hard to put here but I will try. It is part of an API for CLIO legal software.
//Get Matters
$matterarry = matter_numbers ($token);
//get array to just matter numbers
$matternumbers = array(); // initialize the array to be used for the export
foreach($matterarry->matters as $key => $matter) { // loop through all the top level element
// isolate the display number '00001' from '00001-Balter and Son'
$displayNumber = explode('-', $matter->display_number);
$displayNumber = $displayNumber[0];
// push the element the export array using the display_number as the key
$matternumbers[$key] = array(
$displayNumber, // '00001'
$matter->client->name // 'Balter and Son'
);
}
Print_r ($matternumbers);
//export to CSV
$f = fopen('/tmp/matternumbers.csv', 'a'); // open the destination file handler
fputcsv($f, array('display_number', 'name')); // start by adding the column headers
// this can also be done by using named keys in your array,
// or having the first element be the value of the headers
// I'm appending manually here for the sake of simplicity
foreach($matternumbers as $key => $element) {
fputcsv($f, $element); // append each element to the file
}
fclose($f); // don't forget to close the file ;)
function matter_numbers ( $token ) {
//$header = array('Authorization: bearer '.$token);
//print_r ($header);
$header = 'Authorization: bearer '.$token;
echo $header."\r\n";
$ch = curl_init();
//curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_URL, 'https://app.goclio.com/api/v2/matters');
curl_setopt($ch, CURLOPT_HTTPHEADER, array($header));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$resp = curl_exec($ch);
if( !$resp ) {
die('Error: "' . curl_error( $ch ) . '" - Code: ' . curl_errno( $ch ) );
}
else if ( 200 != curl_getinfo( $ch, CURLINFO_HTTP_CODE ) ) {
echo "Bad Response Code!";
echo "\n";
echo "Response HTTP Status Code : " . curl_getinfo( $ch, CURLINFO_HTTP_CODE );
echo "\n";
echo "Response HTTP Body : " . $resp;
}
//print "curl response is:" . $resp;
$resp = json_decode($resp);
//print_r ($resp);
curl_close($ch);
return $resp;
}

I'll try addressing the two parts of your question (1) simplifying the array to isolate specific elements and (2) exporting that to a .csv file
Simplifying the array
For this you'll need to iterate over all the matters element of your original object and push whatever value(s) you wish to export in a new array with the appropriate format
$exportArray = array(); // initialize the array to be used for the export
foreach($initialObject->matters as $key => $matter) { // loop through all the top level element
// isolate the display number '00001' from '00001-Balter and Son'
$displayNumber = explode('-', $matter->display_number);
$displayNumber = $displayNumber[0];
// push the element the export array using the display_number as the key
$exportArray[$key] = array(
$displayNumber, // '00001'
$matter->client->name // 'Balter and Son'
);
}
You then end up with an array that should look a little something like that:
Array [
0 => Array [
0 => '00001'
1 => 'Balter and Son'
]
1 => Array [
0 => '00002'
1 => 'Seamless solutions'
]
]
Alternatively, instead of looping over the array you could use array_map() and obtain a similar result. If you're not familiar with array_map() you can find the official doc here
$exportArray = array_map(function($matter) {
// isolate the display number '00001' from '00001-Balter and Son'
$displayNumber = explode('-', $matter->display_number);
$displayNumber = $displayNumber[0];
return array(
$displayNumber,
$matter->client->name
);
}, $initialObject->matters)
Exporting to CSV
This part is actually quite easy as PHP has a function specifically for this (Official Doc)
$f = fopen('/tmp/myFile.csv', 'a') // open the destination file handler
fputcsv($f, array('display_number', 'name')) // start by adding the column headers
// this can also be done by using named keys in your array,
// or having the first element be the value of the headers
// I'm appending manually here for the sake of simplicity
foreach($exportArray as $key => $element) {
fputcsv($f, $element); // append each element to the file
}
fclose($f) // don't forget to close the file ;)
Mixing the two together
Looping over the elements you want to export twice is tedious and will affect readability and maintainability. This is why you should probably mix those examples together in a single loop.
$file = fopen('/tmp/myFile.csv', 'a'); // open the destination file handler
fputcsv($file, array('display_number', 'name')); // add the column headers
foreach($initialObject->matters as $key => $matter) { // loop through all the top level element
// isolate the display number '00001' from '00001-Balter and Son'
$displayNumber = explode('-', $matter->display_number);
$displayNumber = $displayNumber[0];
// Add the information you need directly in the file
fputcsv($file, array($displayNumber, $matter->client->name));
}
fclose($file);
For the sake of simplicity, I have assumed that your destination file is empty. If you don't know how to make sure a file is empty before starting working with, I suggest you look at this question that sums it up very well.
