Question

Hey all i am trying to search through a CSV file using the following code:

$fh = fopen($myFile, "r");
$os = array(fgetcsv($fh));

if (in_array("12.56.102.44", $os)) {
    echo "Got it!";
}

The CSV is in this format:

"132.89.14.110","41.98.365.111","12.56.102.44","77.295.10.111",

However, that does not work so i am sure i am using it incorrectly…

Any help would be great!

Answer 1

fgetcsv() already returns an array. You should be calling the function like this:

$os = fgetcsv($fh);

Putting the return value inside an array will make the value of $os the following:

array(array("132.89.14.110","41.98.365.111","12.56.102.44","77.295.10.111"))

If there are multiple lines in your file that you need to check, you’ll have to make use of a loop, for example:

$fh = fopen($myFile, "r");
while(($os = fgetcsv($fh)) !== false) {
    if (in_array("12.56.102.44", $os)) {
        echo "Got it!";
        break; // stop the loop, we're done
    }
}
