handle multiple request accessing a json file - php

Question

I have json file in text having a sample data
{"msisdn":"xxxxxxxxxx","productID":"YYYYYYYY","subdate":"2018-09-28 16:30:35","Status":"1"}
{"msisdn":"xxxxxxxxxx","productID":"YYYYYYYY","subdate":"2018-09-28 16:30:35","Status":"1"}
and I have a php code that check the json file for existing msisdn
class JSONObject implements JsonSerializable
{
public function __construct($json = false)
{
if ($json)
$this->set(json_decode($json, true));
}
public function set($data)
{
foreach ($data AS $key => $value) {
if (is_array($value)) {
$sub = new JSONObject;
$sub->set($value);
$value = $sub;
}
$this->{$key} = $value;
}
}
public function jsonSerialize()
{
return (object) get_object_vars($this);
}
}
function checkmsisdnallreadyexists($file,$msisdn)
{
if (is_file($file)) {
if (($handle = fopen($file, 'r'))) {
while (!feof($handle)) {
$line = trim(fgets($handle));
$jsonString = json_encode(json_decode($line));
// Here's the sweetness.
//$class = new JSONObject($jsonString);
$class = new JSONObject($jsonString);
if($class->msisdn == $msisdn)
{
$date1=date_create($class->subdate);
$date2=date_create(date('Y-m-d H:i:s'));
$diff=date_diff($date1,$date2);
if($diff->format('%a') < 31)
{
fclose($handle);
return true;
}
}
}
fclose($handle);
}
}
return false;
}
Everything is working fine initially but when my json file has more than 30 000 records, we have a read timeout. as we have a huge request on my server approx 200k request per hour resulting in efficiency of the whole process.
Can any one provide a solution or a alternate method?
Note: I can't use database here

You can use file() instead of fopen() and fclose()
function checkmsisdnallreadyexists($msisdn){
$file_array = file('give file path',FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
foreach($file_array as $arr){
$msisdn_array = json_decode($arr,true);
$msisdn_value = $msisdn_array['msisdn'];
if($msisdn_value == $msisdn) {
$date1=date_create($msisdn_array['subdate']);
$date2=date_create(date('Y-m-d H:i:s'));
$diff=date_diff($date1,$date2);
if($diff->format('%a') < 31) {
return true;
}
}
}
}
