Question

I have a multidimensional array. The code below outputs one entire column.

<?php       
for ( $row = 1; $row <$arrCSV; $row++ ) {
    echo ''.$arrCSV[$row]['6'].'';  
}
?>

How would I put an “IF” statement to only display the rows the have “CAT” in “$arrCSV[$row][‘4’]”

I am not sure if it is an IF statement?

Answer 1

strpos() is the best function for determining if a particular substring exists (EDITED according to comments below):

$foundOneMatchingRow = FALSE;
foreach ($arrCSV as $row) {
  if (strpos($row['4'], 'CAT') !== FALSE) {
    $foundOneMatchingRow = TRUE;
    echo $row['6'];
  }
}
if (!$foundOneMatchingRow) {
  echo "I couldn't find a matching row!":
}

I have changed the for loop to a foreach because for this particular task, it is less confusing and more readable.
