Please consider the following PHP:
function get_ship_class()
{
$csv = array_map("str_getcsv", file("somefile.csv", "r"));
$header = array_shift($csv);
// Seperate the header from data
$col = array_search("heavy_shipping_class", $header);
foreach ($csv as $row)
{
$array[] = $row[$col];
}
}
How do I pass the resulting array from the above function into
if( in_array() ){
//code
}
?
A slightly abbreviated version, but the same as is being suggested is to return the required data from the function but using array_column() to extract the data...
function get_ship_class()
{
$csv = array_map("str_getcsv", file("somefile.csv", "r"));
$header = array_shift($csv);
// Seperate the header from data
$col = array_search("heavy_shipping_class", $header);
// Pass the extracted column back to calling method
return array_column($csv,$col);
}
And to use it...
if ( in_array( "somevalue", get_ship_class() )) {
//Process
}
If you are going to use this returned value a few times, it may be worth storing it in a variable rather than passing it straight into the in_array() method.
This is the answer that the comments are suggesting.
function get_ship_class(){
$array = array();
$csv = array_map("str_getcsv", file("somefile.csv", "r"));
$header = array_shift($csv);
// Seperate the header from data
$col = array_search("heavy_shipping_class", $header);
foreach ($csv as $row) {
array_push($array, $row[$col]);
// array_push($array, "$row[$col]"); // You may need it as a string instead.
}
return $array;
}
if( in_array("whatever_you_are_looking_for", get_ship_class()) ){
//code
}
