[SOLVED] PHP Strings

[spookykl]

Hi all,

 

I am fairly new with php coding and this may seem like a stupid question, but how do I (using a for loop), loop through each of my variables? (look at the example below).  I'm not sure how to explain it, but it goes something like this:

 

$TXT1 = "Hello";

$TXT2 = "My Name Is";

$TXT3 = "PHPFREAKS";

$TXT4 = "ByeBye";

 

for ($i = 1; $i<=4; $i++)

{

  $output .= $TXT . $i;  <--  how can I combine this and make it $TXT1 or $TXT2, etc...

}

 

Thank you!

<?php

$TXT1 = "Hello";
$TXT2 = "My Name Is";
$TXT3 = "PHPFREAKS";
$TXT4 = "ByeBye";

for ($i = 1; $i<=4; $i++) {
   $output .= ${'TXT' . $i};
}

?>

do some reading cause these things called arrays are amazing:

Loop structures:

http://us.php.net/manual/en/control-structures.for.php

 

http://us.php.net/manual/en/control-structures.foreach.php *

 

foreach is a very powerful tool for running through an array.

 

 

Edit:

with arrays you can accomplish that in a cleaner way

<?php
$txt = array();
$txt[1] = "Hello";
$txt[2] = " My Name Is";
$txt[3] = " PHPFREAKS";
$txt[4] = " ByeBye.";
foreach($txt as $value){
echo $value;
}
?>

No need to know your array's size

Thank you! It works.  Let me read up on php =)

If you have a list of sequentially named variables, it is a sure bet that you should be using an array.

 

A list of sequentially named variables will require you to carry around another variable that says how many of them there are. With an array, you don't need to waste time and code doing that.

Especially if what was re-stated only existed because the earlier post was edited to include that information.
