在PHP数组中搜索子字符串

Question

I am trying to find a particular string in a PHP array as below.

Array ( [0] => Array ( [0] => sku,qty,is_in_stock ) [1] => Array ( [0] => EBCDAA014MAS34B,149.000000,1 ));

I am preparing the above array as below and I am storing it in a variable called $listing

And I am using array_find() function to do so.

function array_find($needle, array $haystack)
{
    foreach ($haystack as $key => $value) {
        if (false !== stripos($value, $needle)) {
            return $key;
        }
    }
    return false;
}

$hello = array_find('EBCDAA014MAS34B', $listing);
echo $hello;

But still, I am getting the return as false. Can anyone kindly tell me which is the right way to do this?

Answer 1

Your array is an array of arrays where your string is the first item in each of those arrays which will be $value[0]

Try changing this line:

if (false !== stripos($value, $needle)) {

To this line:

if (false !== stripos($value[0], $needle)) {

Simply you can use in_array() PHP Function, see below example.

    $listing = Array ( [0] => Array ( [0] => sku,qty,is_in_stock ) [1] => Array ( [0] => EBCDAA014MAS34B,149.000000,1 ));
in_array('EBCDAA014MAS34B', $listing)
