How to fix check one value present in between two numbers

I need to check one user input value is present in between two number type value or not but as per my code its not working. I am explaining my code below.

$post_code=751011
$dataCed=[{"region_id":"4","zip_from":"754346","zip_to":"754346"},{"region_id":"4","zip_from":"754345","zip_to":"754345"},{"region_id":"4","zip_from":"754130","zip_to":"754230"},{"region_id":"3","zip_from":"226012","zip_to":"226025"},{"region_id":"2","zip_from":"751001","zip_to":"751030"},{"region_id":"1","zip_from":"1000","zip_to":"1500"}]
//echo json_encode($dataCed);
$flag=0;
foreach ($dataCed as $key => $value) {
    if ($post_code >= (int)$value['zip_from'] && $post_code <= (int)$value['zip_to']) {
        $flag=1;
        $reg_code=$value['region_id'];
        break;
    }
}
echo ($flag);exit;

Here I should get the flag value=1 as postcode(i.e-751011) present within 751001 & 751030 but I am getting the output as 0 which is wrong.So how to fix this code so that I can get the right output.

You can make use of array_filter to check this as given below.

<?php
$post_code = 751011;
$dataCed = '[{"region_id":"4","zip_from":"754346","zip_to":"754346"},{"region_id":"4","zip_from":"754345","zip_to":"754345"},{"region_id":"4","zip_from":"754130","zip_to":"754230"},{"region_id":"3","zip_from":"226012","zip_to":"226025"},{"region_id":"2","zip_from":"751001","zip_to":"751030"},{"region_id":"1","zip_from":"1000","zip_to":"1500"}]';
$dataCed = json_decode($dataCed);

$result = array_filter($dataCed, function($v1) use ($post_code){
    if ((int)$post_code >= (int)$v1->zip_from && (int)$post_code <= (int) $v1->zip_to) {
        return $v1;
    } 
});

$found = count($result) > 0 ? true : false;
var_dump($found); // This gives bool(true)

Try the followig code:

$post_code = 751011;
$dataCed = '[{"region_id":"4","zip_from":"754346","zip_to":"754346"},{"region_id":"4","zip_from":"754345","zip_to":"754345"},{"region_id":"4","zip_from":"754130","zip_to":"754230"},{"region_id":"3","zip_from":"226012","zip_to":"226025"},{"region_id":"2","zip_from":"751001","zip_to":"751030"},{"region_id":"1","zip_from":"1000","zip_to":"1500"}]';
$myArray = json_decode($dataCed);
$flag = 0;
foreach ($myArray as $key => $value) {
    if ($post_code >= $value->zip_from && $post_code <= $value->zip_to) {
        $flag = 1;
        $reg_code = $value->region_id;
        break;
    }
}
echo ($flag);
exit;

Then you should get the exact output. The problem was you need to decode the JSON array properly.

Something doesn't seem right in the code you provided, but assuming $dataCed is JSON data, you could do:

<?php

$post_code = 751011;
$dataCed = '[{"region_id":"4","zip_from":"754346","zip_to":"754346"},{"region_id":"4","zip_from":"754345","zip_to":"754345"},{"region_id":"4","zip_from":"754130","zip_to":"754230"},{"region_id":"3","zip_from":"226012","zip_to":"226025"},{"region_id":"2","zip_from":"751001","zip_to":"751030"},{"region_id":"1","zip_from":"1000","zip_to":"1500"}]';
$dataCed = json_decode($dataCed);

$flag = 0;

foreach ($dataCed as $key => $value) {
    $value = (array) $value;
    if ($post_code >= (int)$value['zip_from'] && $post_code <= (int)$value['zip_to']) {
        $flag=1;
        $reg_code=$value['region_id'];
        break;
    }
}

echo ($flag) . "<br>";
echo ($reg_code);
exit;
