Question

I’m a newbie and I have a very basic question about PHP arrays

Code:

 While(!feof($file_handle))
  { 
     $SecondRow = fgets($file_handle); //gets row
     $trimmed = trim($SecondRow); //removes extra bits
     $replace = array("'"); 
     $finalstring = str_replace($replace, "_", $trimmed); //Still a string w/o "'"'s

     $CleanString = preg_split("/[\s]*[,][\s]*/", $finalstring); //creates the array

     //print_r($CleanString);    
     echo "Row " . $CleanString[1]. "<br/>"; //??????
   .....
 }//end while

the opened file has the following:

0001,sparta 
0005,PURCHASING

…
…
…

Question:
When I echo “Row ” . $array[0], I get the first column as expected. But when I echo “Row ” . $array[1], I get an the “Undefined offset: 1” error. When the string is read into the array (via preg_split) aren’t both
array[0]->0001 and array[1]->sparta set?

thanks.

Looking at your entire code, you’re essentially replicating a native function like fgetcsv() or one of it’s equivalents.

Just pick one and be done 🙂

As far as determining how to use the array, as noted in the comments use print_r or var_dump() to guide you. Also read up on PHP Arrays
