problem with lower casing and then searching value

mrbaseball34

if...

      $data[0] = 'Part Number';

then why would this:

      $data_0 = strtolower($data[0]);
      echo $data[0]. " : ".$data_0. " : ".strpos($data_0, 'part');

produce:

Part Number : part number : 0

strpos returns the index of the first occurrence of the string you are searching for. In this case index 0. To test if 'part' is in the string do this:

If (strpos ($data_0, 'part') === false)
{
  //not found
}

Well I want to know if the string actually contains the word 'part'

strpos doesn't seem effective for that, I guess, so what would I use?

this???

  if(!strpos($data_0, 'part') {

You can still use strpos for this. The only issue you have to be careful of is when strpos returns 0 because this is an index value that also represents a false. So if you want to know if the string contains the word part you would do this.

if (strpos($data_0, 'part') !== false)
{
  //'part' found in string
}
else
{
  //'part' not found
}

If you're having trouble this link should clear things up http://php.net/manual/en/function.strpos.php

Thanks for that. I was assuming that string indexes would begin with 1 because the first character in a string... anyway...

I'm trying to modify an import process that handles both CSV and tab delimited files and am having trouble when the file includes the header line and also when the import file is tab delimited because we are using :

while (($data = fgetcsv($handler, $filesize, ",")) !== FALSE)

I am testing to see if there is a tab in the line ($data[0]) and then exploding it back into the $data array like this:

if (strpos($data[0], "\t") !== false) {
  $data = explode("\t", $data);
}

But having problems with the subsequent lines.
Any ideas?
