Converting array in Json PHP output not as expected - php

Question

I have some problem when I convert an PHP array to Json. for more contex this is the code:
`<?php
$Users = array();
$file = fopen('usersFile.csv', 'r');
$row = fgets($file);
$ColumnKeys = explode(',', $row);
while (!feof($file)) {
$row = fgets($file);
$userData = explode(',', $row);
for ($i=0; $i<sizeof($columnkeys); $i++) {
$user[$columnKeys[$i]] = $userData[$i];
}
array_push($Users, $user);
}
fclose($file);
echo json_encode($Users);
?>`
The csv file containing the user data is this:
id,name,docNumber,dateBirth
1,Mario Mario,1694370,06/11/1953
2,Pau Pep,1725614,24/04/1964
The output look like this:
[{"id":"1","name":"Mario Mario","docNumber":"1694370","dateBirth\r\n":"06\11\1953\r\n"}, {"id":"2","name":"Pau Pep","docNumber":"1725614","dateBirth\r\n":"24\04\1964\r\n"}]
I don't know why in the output the $Users array contain Metacharacter in the dateBirth and their value. Is driving me mad.

Answer 1

it seems there is an option for json_encode called JSON_UNESCAPED_SLASHES
<?php
$Users = array();
$file = fopen('usersFile.csv', 'r');
$row = fgets($file);
$columnKeys = explode(',', trim($row));
while (!feof($file)) {
$row = fgets($file);
$userData = explode(',', trim($row));
for ($i=0; $i<sizeof($columnKeys); $i++) {
$user[$columnKeys[$i]] = $userData[$i];
}
array_push($Users, $user);
}
fclose($file);
echo json_encode($Users, JSON_UNESCAPED_SLASHES);
?>
Output:
[{"id":"1","name":"Mario Mario","docNumber":"1694370","dateBirth":"06/11/1953"},{"id":"2","name":"Pau Pep","docNumber":"1725614","dateBirth":"24/04/1964"}]
