Question

I have imported a CSV to fill a multidimensional array. $arrCSV.

<?php     
  $foundOneMatchingRow = FALSE;
  foreach ($arrCSV as $row) {
    if (strpos($row['5'], $val) !== FALSE && strlen($row['5']) > 4) {
      $foundOneMatchingRow = TRUE;
      echo $row['6'];
    }
  }
?>

The above code outputs from the value of $val = $_GET['menu']; which is done buy the URL.

I would like to make a search if possible please based on words in $row['6'];.

There will be a search on the page which will pass the search to the URL.

Which would look something like http://example.com/search.php?val=dogs

So the code would look for ANYTHING that relates to dog in $row [6]

I hope I have been clear. Any gudiance would be more than welcome. I am testing everything now.

Thank you

Answer 1

if (strpos($row['6'], $val) !== FALSE) will evaluate to true if $row['6'] contains “dog” (if $val‘s value is “dog”). That is, will evaluate to true as well if the string in $row['6'] is “bulldog” or “whateverdogwhatever”.

BTW, why do you need this condition: strlen($row['5']) > 4? (which I guess should be at least strlen($row['6']) > 4 if you search on $row['6']).

Something else: aren’t you confusing strings and integers? Maybe if (strpos($row['6'], $val) !== FALSE) should be if (strpos($row[6], $val) !== FALSE)?

EDIT

I would suggest to define constants for your CSV columns, for readability.

What about for example:

define('CSV_ID', 5);
define('CSV_TEXT', 6);

//...
foreach ($arrCSV as $row) {
  if (strpos($row[CSV_TEXT], $val) !== FALSE && strlen($row[CSV_ID]) > 4) {
    //...
    echo $row[CSV_TEXT];
  }
}
