RE: [PHP] php equivalent for `command`

I was hoping to avoid concatenation to make my code more legible (less illegible?). I take it then that there is no equivalent for the use of ` in Unix. -----Original Message----- From: Plutarck [mailto:aemuli@spamclause-yahoo.com] Sent: 18 April 2001 15:13 To: php-general@lists.php.net Subject: Re: [PHP] php equivalent for command > In the second set of code lines, what I need to do is somehow bracket off the $test++ so it is evaluated before being echoed. You need to use the string concantenation operator (a period) to use things like $test++, else PHP get's confused. > echo "Value of test: $test++ <BR>"; To get that to work like you want it to, you need only do: echo 'Value of test: ' . $test++ . ' <BR>'; It's functionally the same, no brackets needed. If you want it to be evaluated BEFORE it's echoed, you need to use: echo 'Value of test: ' . ++$test . ' <BR>'; -- Plutarck Should be working on something... ...but forgot what it was.

I want to output quite long and complicated strings that may involve evaluated variables, calls to functions etc. But I also want it to as legible as possible. But even something simple along the lines I quoted gives me problems. See the following code and its output > > <?php > $test=1; > echo $test++ . "<BR>"; > echo $test++ .
