使用in_array（）的Foreach循环不起作用

Question

I am having trouble getting an in_array() to work. The in_array() is returning false thus the array_push is not being called. I cannot figure out why. The $zipsArray and $propsArray both have data and I have confirmed that there are matching zips in each array. I have also confirmed that each $val has a value.

Help is much appreciated!

        $zipsArray = self::getZipRadius('vhdf',100);

        $propsArray = self::allProps($dbc,$source);

        $localArray = array();

        foreach($propsArray as $key => $val){

            if(in_array($val['zip'], $zipsArray, true)) {

                $propitem = array(
                    'propid'    => $val['propid'],
                    'street'    => $val['street'],
                    'city'      => $val['city'],
                    'state'     => $val['state'],
                    'zip'       => $val['zip'],
                    'beds'      => $val['beds'],
                    'baths'     => $val['baths'],
                    'garage'    => $val['garage'],
                    'type'      => $val['type'],
                    'sqft'      => str_replace(array('.', ','), '' , $val['sqft']),
                    'descript'  => self::clearString($val['descript']),
                    'listdate'  => $val['listdate'],
                    'askprice'  => $val['askprice'],
                    'repairval' => $val['repairval'],
                    'source'    => $val['source']
                );

                array_push($localArray, $propitem);

            }   

        }

        return $localArray;

The $zipsArray currently has this data. I shortened it a bit to save scrolling as it currently holds 622 items.

array(1853) { [0]=> string(5) "12723" [1]=> string(5) "12736" [2]=> string(5) "12736" [3]=> string(5) "12741" [4]=> string(5) "12745" [5]=> string(5) "12760" [6]=> string(5) "12766" [7]=> string(5) "12767" [8]=> string(5) "13020" [9]=> string(5) "13021" [10]=> string(5) "13021" [11]=> string(5) "13021" [12]=> string(5) "13021" [13]=> string(5) "13021" [14]=> string(5) "13021" [15]=> string(5) "13022" [16]=> string(5) "13026" [17]=> string(5) "13026" [18]=> string(5) "13027" [19]=> string(5) "13027" [20]=> string(5) "13027" [21]=> string(5) "13027" [22]=> string(5) "13027" [23]=> string(5) "13028" [24]=> string(5) "13029" [25]=> string(5) "13030" [26]=> string(5) "13031" [27]=> string(5) "13031" [28]=> string(5) "13031" [29]=> string(5) "13032" [30]=> string(5) "13032" [31]=> string(5) "13032" [32]=> string(5) "13032" [33]=> string(5) "13033" [34]=> string(5) "13034" [35]=> string(5) "13035" [36]=> string(5) "13035" [37]=> string(5) "13035" [38]=> string(5) "13035" [39]=> string(5) "130 36" [40]=> }

An example of $val is

[52]=>
  array(15) {
    ["propid"]=>
    string(6) "274672"
    ["street"]=>
    string(10) "320 Easton"
    ["city"]=>
    string(5) "Depew"
    ["state"]=>
    string(2) "NY"
    ["zip"]=>
    string(5) "14043"
    ["beds"]=>
    string(1) "2"
    ["baths"]=>
    string(1) "1"
    ["garage"]=>
    string(1) "0"
    ["type"]=>
    string(13) "Single Family"
    ["sqft"]=>
    string(3) "972"
    ["descript"]=>
    string(365) "This 972 square foot single family home has 2 bedrooms and 1.0 bathrooms. Located in a desirable part of Depew, property has a lot to offer besides the location in a quite neighborhood it includes a nice size back yard, small front yard for easy maintenance. Just off of a main road close to amenities. 

This Discounted property wont last long contact today."
    ["listdate"]=>
    string(10) "2016-07-13"
    ["askprice"]=>
    string(5) "25000"
    ["repairval"]=>
    string(6) "75,000"
    ["source"]=>
    string(4) "prop"
  }

If the third parameter strict of in_array is set to TRUE then the in_array() function will also check the types of the needle in the haystack.

Remove the strict mode (third_parameter) or make sure both arrays contains zip codes as string (The second is more fool proof). Debug data shows one of the arrays containing zip codes as a string while the other contains it as an integer.
