Newb question i think

[Brian W]

if i have $Value1 = "hello"; $Value2 = "world";

and I want to combine the two like $helloworld

how could I do that?

[Maq]

$Value1 .=  $Value2;

[Brian W]

let me revise that

___

if i have $Value1 = "hello"; $Value2 = "world"; $Value3 = "HI"

and I want to combine the two three $helloworld = HI

how could I do that?

I'm sorry I don't understand this question.  The '.' is a concatenation string.  So when you write

$Value1 .= $Value2;

 

It's the same thing as:

 

$Value1 = $Value1 ."". $Value2;

 

If this doesn't help please just tell me the three vars and what final result you want.

[Brian W]

The variables are from a data base. I'm trying to populate certain cell (out of a 50x50 cell table). If $row_pos['left'] = "4" and $row_pos['top'] = "3", and $row_pos['word'] = "HI"

I want it to come out as $cell4x3 = "HI"

in my table in the cell 4 over and 3 down, there is

echo $cell4x3

[DarkerAngel]

this is the best I can do for ya that does what you want.

 

<?php

eval("\$cell" . $row_pos['left'] . "x" . $row_pos['top'] . " = \"" . $row_pos['word'] . "\";");

?>

 

God knows why you need something like that but there it is.

What are you trying to achieve exactly? I'm sure it'll be just as if not easier to keep it in arrays or even transform it into a slightly easier to manage array to achieve the desirable outcome.

[GingerRobot]

Well, it is possible like so:

 

$Value1 = "hello"; 
$Value2 = "world"; 
$Value3 = "HI";
${$Value1.$Value2} = $Value3;
echo $helloworld;

 

However, i agree with ProjectFear that there might be a better solution in the long run if you explain your problem some more.

[F1Fan]

I agree. A multidimensional array is your best bet.

 

<?php
$Value1 = "hello"; 
$Value2 = "world"; 
$Value3 = "HI";
$array[$Value1][$Value2] = $Value3;
print_r($array);
?>

Sorry, i'm making a game board that has 40 x 40 cells. Each cell was going to have a string (such as 2 across and 1 down would have $x3y1)

Players would add entries into the database with a picture's source from a list I have (20x20px pics) and x and y positioning choices. I then have a repeat field that takes the info from the database and converts it into the image script in the right place.

 

$x3y1 = "<img src=\"$row_pos['src']\" > \\ or something like that.

 

I changed over to a repeating background of chess board like squares to create my board (less script, better refresh time) and set it up to have absolute positioning instead. (tid bit from it: absolute; left; ".10+(20*$row_pos['X'])."...(*20 because each square is 20pixels and + 10 because the screen margins 10 from the top and left.))
