Why does in_array() wrongly return true with these (large numeric) strings?

Question

I am not getting what is wrong with this code. It\'s returning \"Found\", which it should not.

$lead = \"418176000000069007\";
$diff = array(\"41817600000006         


        

Answer 1

If that is your problem and you really want to compare/find in array then there is a trick

$lead = "a418176000000069007";
$diff = array("a418176000000069003","a418176000000057001");

if (in_array($lead,$diff))
    echo "Found";
else
    echo "Not found";

i.e. somehow you have to prepend a perticular character to every number. They will behave as strings in comparison and hence give correct result.
