concatanate 2 strings

[Desmond]

Can someone please tell me how to concatanate to strings like this
please
$name = $_POST["Name"];
$from = $_POST["Email"];

$headers = "From: $name $from\r\n";

i beleve in C there is a strcat() is this similar.
if so is there an online site for PHP function.

Did you try that? It ought to work exactly as you wrote it.

However, if you want a valid "From" header, put the email address in angle
brackets like this:

$headers = "From: $name <$from>\r\n";

And please check that the $_POST[] data is valid. For example, check that
the email address is correctly formatted, and that the "Name" data doesn't
contain any newline characters. You might also need to apply stripslashes()
to the data from your form.

The PHP documentation is here: <http://www.php.net/docs.php>

In PHP the concatenation operator is the dot. So you can concatenate two
strings like:

$concatenated = $string1.$string2;

This is also described in the manual (which is really a great ressource
for PHP developers):

That works too.

That also works.

Full stop is the concatenation operator, but php also has the quite unique
mechanism for inserting variables directly into strings.

$foo .= $bar;
is just short for
$foo = $foo . $bar; and they both concatenate the two variables.
But this works as well, just in a slightly different way:
$foo = "$foo$bar";

Variables inside double qoutes are replaced with their values. inside single
qoutes they'r not evaluated, but interpreted literally.

Not wanting to repeat what has been written, but I think someone should
point out that the concatenation of global variables has to be done with the
.. (dot) operator, whereas using local variables, like you have, you can
directly stick strings together _or_ use the . operator.

So these are all ok:

$bigstring = "$first $second";
$bigstring = "$first some non variable text $second";
$bigstring = $first . $second;
$bigstring = $first . " some non variable text " . $second;

But with globals only . concatenation is ok:

$bigstring = $_POST['Name'] . $_POST['Email'];
$bigstring = "normal text with $localvariable" . $_POST['Name'] . "more
text";

(above code has not been tested in real-life) :>

This is fine and works perfectly (you can drop the quotes around the key
name when inside double quotes):

$localvariable = 'white background';
//$_POST['Name'] previously set to 'John'
$bigstring = "normal text with $localvariable for $_POST[Name] to read.";

outputs: normal text with white background for John to read.

and...

$localvariable = 'white background';
//$_POST['Name'] previously set to 'John'
$bigstring = "normal text with $localvariable for '$_POST[Name]' to read.";

outputs: normal text with white background for 'John' to read.
