explode() function

[boumbo]

Hy, Im trying to insert into an array part of a string from a text file.

The text file contains characters that I wish to insert in the array. A --> * character is between each entry that I want to separate in the array. Therefore it looks like this:

// Write all data to people.txt
$fp = fopen ( "people.txt", "a");
fwrite ($fp, $inputString);
fclose ($fp);

$tokensArr = Array();

$filename = "people.txt"; 	// File which holds all data
$fp = fopen ( $filename, "r");
$content = fread( $fp, filesize( $filename ) );
fclose($fp);

$tokensArr = explode ("*",$content);

echo sizeof($tokensArr);

When I view the sizeOf the Array it shows that I have 2 elements in the array, but in fact I only have one entry (only one * character in people.txt)

people.txt:

*Cooper<br>Rockstar Poser<br>No<br>

Why is the size of the array 2 and not 1 ?

Hi,

When the string is splitted at the * character, you will get one index with the data before the character (in this case nothing) and one index with the value after (in this case "Cooper<br>Rockstar Poser<br>No<br>").

Yours, Erik.
