colinexl Posted June 27, 2006 Share Posted June 27, 2006 Hey everyone, I'm trying to do something like this in PHP 4.3.2:[code]<?php$string = "This is\tan example\nstring";$tok = strtok($string, " \n\t");$output = "<html><table><tr>";while ($tok != false){ $output += "<td>" . $tok . "</td>"; $tok = strtok(" \n\t");}$output += $output . "</tr></table></html>";echo $output;?>[/code]But instead of getting a formated table with "This is an example string", i get a 0. I tried something simple like[code]$output = "hi ";$output += "there";[/code]expecting to get "hi there" as the result but instead, i got a 0. I'm forced to do $output = $ouput . "some string..". The thing is that I know I've used the += to concatenate strings together, but I was using PHP 5. Is this something that's not available in PHP 4? Thanks!

Barand Posted June 27, 2006 Share Posted June 27, 2006 The concatenation operator in PHP is ".", not "+"$a = "Hello"$a .= " World";echo $a; // Hello World Quote Link to comment Share on other sites More sharing options...
