Remap CSV as an array using first row as keys - php

Question

Let's assume I have a CSV file, which looks like:
[Line 1]: ID, Name, Birthday, Phonenumber, Email
[Line 2]:
[Line 3]: 1, Jim, 1978-02-01, 555-23-256, jim.doe#donotreply.com
[Line 4]: 2, Mia, 1985-12-21, 555-23-876, mia#donotreply.com
[Line 5]: 3, Wil, 1962-05-07, 555-23-456, wil.doe#donotreply.com
Now I am trying to wrap my head around this question:
How can I parse this file with PHP to get the following array?
$people = array(
[1] = array(
[Name] => "Jim",
[Birthday] => "1978-02-01",
[Phonenumber] = "555-23-256",
[Email] => "jim.doe#donotreply.com",
),
...
);
Any idea?

Answer 1

Use fopen and fgetcsv
In order to do this you need to first write a function for retrieving the data from the CSV and storing it in a variable, the function below will do this using fopen.
First, you'll need a function to read the CSV:
function utf8_fopen_read($fileName) {
$fc = iconv('windows-1250', 'utf-8//IGNORE', file_get_contents($fileName));
$handle = fopen("php://memory", "rw");
fwrite($handle, $fc);
fseek($handle, 0);
return $handle;
}
Once you've done this you'll want to manipulate the data you've just retrieved so you can create a multi-dimensional array of the results, populating the data into the associative keys like you described in your question.
Now we are going to make a call to the function above and store the results in $data, using a while loop we are going to iterate through the entire CSV and store all of the information into $people row by row.
Populating your array:
$people = [];
if(($handle = utf8_fopen_read('path/to/csv.csv')) !== FALSE) {
while(($data = fgetcsv($handle, 0, ',')) !== FALSE) {
$people[$i] = [];
for($c = 0; $c < count($data); $c++) {
$info = $data[$c];
if($i == 0) $fields[$c] = str_replace(' ', '', $info);
if($i > 0) $people[$ii][$fields[$c]] = $info;
}
if($i > 0) $ii++;
$i++;
}
fclose($handle);
}
