You need to match something at the beginning. Try this:
preg_match('/([^]*end)/', $curl_response, $matches);
Assuming a match, you can then look to $matches[1] for your content.
That did it. In my case, I know that the first letter is capitalized, so I
used:
preg_match('/[A-Z][^]*end/', $curl_response, $matches);
Thanks for your help.

[PHP] help with preg_match
Hello,
I am trying to use preg_match to match something from an html file.
Within the html file is some text that looks like:
spanSomething, something end/span
I know that the text ends 'end', but I don't know what the Something,
something is. I am using preg_match as follows:
preg_match('/[^]*end/',$curl_response,$matches);
I want to match 'end' and everything before it that is not ''.
The problem appears to be with the ''. I have tried escaping (\), but
it didn't make a difference. The php script hangs when it tries to run
this function.

You could try this
preg_match_all('/(span[^]**)(.*)(/span[^]*)/is',$curl_response,$matc
hes);
print_r($matches);

[PHP] Help with preg_match and windows domain logins...
I'm trying to do what should be a very simple regex, but can't seem to get
PHP to work, yet regex-coach and even an XML .XSD work fine:
Valid forms of a windows logon are:
foo\bar
\\foo\bar
function isValidWinLogon($logon)
{
//$logon = 'foo\\bar';
$logon = '\\foo\bar';
print PPRElogon = '$logon'BR/PRE\n;
preg_match('/()?.+\\.+/', $logon, $matches);
//preg_match('/()?.+(\\).+/', $logon, $matches);
print_r($matches);
return (count($matches) 0);
}
I'm obviously passing in the strings, but for testing, I tried to hard-code
it.
First, when I use single ticks, I thought that meant to be taken literally.
Seems I still have to escape (\) the backslashes.
In either case, the $matches array is EMPTY.
Further more, WTF do I get this error:
Compilation failed: missing ) at offset 12 (pointing to the commented out
preg_match.
WTF should adding a set of parenthesis cause a compilation error?!

WTF do you need so many WTFs?
Adding a set of parenthesis isn't causing the error. Adding an
open-bracket and then an escaped close-bracket is causing your error.
The missing ) at offset 12 is a bit of a clue there.
Backslashes are special characters to both single-quoted strings AND
regular expressions so if you use them, you're normally going to have
to escape them twice.
So if you want optional double backslashes, followed by any characters
followed by a backslash followed by any characters - which is what I'm
guessing you were aiming at, you'd start off with this:
/^(\\)?.+\.+$/
you need to escape the backslashes for the regular expression engine
so you get this:
/^()?.+\\.+$/
and you're supplying it in a single-quoted string, which also needs
the backslashes escaped, so you get this:
'/^()?.+.+$/'
by which point you should be swearing at Microsoft for choosing such a
stupid character for a login string delimiter.
Clear?

[PHP] help with preg_match
Hi,
I'm trying to write a function that validates the input in a textarea. I
just want to allow alphanumrical characters, and if the user enters
anything else, I display an error message by calling error().
But the following doesn't work. Even if I enter hello in the textarea,
I get the error message. What am I missing?
// validate entered text in textarea
function validate_textarea($unchecked_text) {
if (!preg_match (/^[a-zåäö0-9]$/is, $unchecked_text)) {
error(You have used unlegal characters, just alphanumeric is ok.);
}
}
Best regards,
Anders

Re: [PHP] help with preg_match
You need to tell preg_match that there will be multiple characters. Right
now, you're searching for one, and only one.
if (! preg_match ('/^[a-z0-9]+$/', $unchecked_text)) {
The + means one or more matches to the range in brackets.
