preg_replace...

CrashRoX

Im working on a small templating function... Cant seem to figure out why this wont work... The point is I declare a local variable ($_var). That same variable is found in $text, but is enclosed by . the preg_replace function should find and replace that... Any ideas where I messed up?

$_var = "TEST";
$text = "<!--_var-->";
$x = preg_replace("/\\<!--(\\S+)\\-->/e", "\\$\\\1", $text);
echo $x

that should do the trick.

$_var = "TEST";
$text = "<!--_var-->";
$x = preg_replace("/<!--(\S+)-->/e", "$\\1", $text);
echo $x;

Very Wierd... Your alterations work perfectly accept under one condition... Take a look at:

$_var = "TEST";
$_var1 = " TEST1";
$text = "<!--_var--><!--_var1-->";
//$text = "<!--_var-->,<!--_var1-->";
$x = preg_replace("/<!--(\S+)-->/e", "$\\1", $text);
echo $x;

The only way to make that work is to put an actual space between --> and <!--. It wont work with or without a character, it only likes the space. ... Any ideas?

give this a shot instead. when they were compounded together it was matching the end of the comment as part of the (\S+) expression.

<?

$_var = "TEST";
$_var1 = "test2";
$text = " <!--_var--><!--_var1--> ";
$x = preg_replace("/<!--([a-zA-Z0-9_]+)-->/e", "$\\1;", $text);
echo $x;

?>

Works perfectly! Thank you.
