PHP variable help

[purg]

I posted here because this isnt strictly a web design problem but hoping you can help (or point me in the right direction).

Im writting a PHP script to display data on a userbar which works

PHP Code:

$userbar_text = "Checked : 1 $xa of $x work";
imagestring($im, $font, 125,    3, $userbar_text, $colour); 


The problem is that im wanting to move $userbar_text into a config file but cant get embedded $xa of $x to parse correctly.

So the above in short has become:-
config.inc.php

PHP Code:

$rsdata = array(
//        id        img        cl1    cl2    cl3    fnt    x        y    "text"
array(    "001",    "001",    0,    0,    0,    3,    125,    3,    "Checked : 1 \$xa of \$x work"),
array(    "002",    "002",    0,    0,    0,    3,    125,    3,    "Checked : 2 \$xa of \$x work"),
array(    "003",    "003",    0,    0,    0,    3,    125,    3,    "Checked : 3 \$xa of \$x work"),
); 


script.php

PHP Code:

require_once('includes/config.inc.php');
...
...
foreach ($rsdata as $i => $tempvalue) {
    if ($imgnum == $rsdata[$i][0]) {
    $userbar_text = $tempvalue[8];
    $colour = imagecolorallocate($im, $tempvalue[2], $tempvalue[3], $tempvalue[4]);
    ImageFill($im, 0, 0, $grey);
    imagestring($im, $tempvalue[5], $tempvalue[6], $tempvalue[7], $userbar_text, $colour);
    }
} 


but whatever I try, userbar displays either the text "Checked : 3 $xa of $x work" without changing $xa or $x or "Checked : 3 of work" with the variables being blank.

I'm not a php programmer, but I can't see where you are declaring what vars $x and $xa?

I'm guessing that $xa should be your $rsdata array length?
And $x is your current position in the array?

I get the impression this isn't the whole script.

As above $xa $ x aren't set, and when you split the array arrays into key value pairs where is imgnum set for the comparision with 001, 002 etc?

Yea thats far from the whole script as its a project in the making, but this might make it easier.

PHP Code:

require_once('includes/config.inc.php');
$xa = "apple";
$x = "plum";
echo $tempvalue[3][8]; 


Im wanting the script to output "Checked : 3 apple of plum work"
ive highlighted the vars taken from config.inc.php with $x $xa being substituted.


In the example posted $tempvalue[3][8] is the same but obviously this changes place and wording allowing the user to config the output.

After posting I reading some of your comments I googled for "replace" and came up with a answer to my problem.

preg_replace
^ ive not see this before but does the job

config now looks like this

PHP Code:

$rsdata = array(
//        id        img        cl1    cl2    cl3    fnt    x        y    "text"
array(    "001",    "001",    0,    0,    0,    3,    125,    3,    "Checked : 1 #xa# of #x# work"),
array(    "002",    "002",    0,    0,    0,    3,    125,    3,    "Checked : 2 #xa# of #x# work"),
array(    "003",    "003",    0,    0,    0,    3,    125,    3,    "Checked : 3 #xa# of #x# work"),
); 


and the script using preg_replace

PHP Code:

foreach ($rsdata as $i => $tempvalue) {
    if ($check_user == $rsdata[$i][0]) {
    $imgnum = $tempvalue[1];
    }
    if ($imgnum == $rsdata[$i][0]) {
    $userbar_text = preg_replace("/#xa#/", $xa, $tempvalue[8]);
    $userbar_text = preg_replace("/#x#/", $x, $userbar_text);
    $colour = imagecolorallocate($im, $tempvalue[2], $tempvalue[3], $tempvalue[4]);
    ImageFill($im, 0, 0, $grey);
    imagestring($im, $tempvalue[5], $tempvalue[6], $tempvalue[7], $userbar_text, $colour);
    }
} 


Thanks for your comments, from this I was able to find an answer via google.
