Wow, worked perfect. Thank you. I just made it (preg_match_all)
more words/chars[<a href="#c_1" id="ids_1" title="Hello">2</a>]more words/chars
How can I also find the number 2 in (...>2</a...) in the same sentence
and made preg_match_all make array of two items
Array
(
[0] => Hello
[1] => 2
)

after read all your replies, i understand and want to redefine the problem.
if user clicks on the hyperlink on list.php page, i want to open a new
windows for user to update info. once user clicks update on update.php
page, i want to close the update.php page automatically and refresh list.php
page. i think this is possible. can someone give me suggestions how to do
this?

Yes. Ask on a JavaScript list. Anything like that is done on the
client side (in the browser), which would be handled by JavaScript,
VBScript, or something similar - not PHP. PHP only handles the server
side of things, before the HTML (or other content) is even passed
through Apache (or whatever HTTP server is running) to serve to the
client.

Yes, you will need something like this http://www.wildbit.com/labs/modalbox/ or
a regular javascript popup (window.open).
Modalbox is based on prototype and scriptaculous, but there are other
lightweight solutions over there too (someone mentioned jQuery and Thickbox I
think, and there's also a Mootools version called MOOdalbox or something).
This is something you need to program on the client-side (at least most of it),
so it's not about PHP.

Anyone have a nice color scheme for php syntax highlighting in vim? I
am using elflord and it is nice but the comment color is like the
function color which makes it confusing.

I do all of my coding in ViM, and I just use the default colors.
The basic scheme is like this:
* HTML syntax is highlighted outside of the PHP tags
* PHP tags are purple
* Comments are dark blue
* Known functions are turquoise
L> Function parameters are white, unless they are quoted
or variables
* Variables are turquoise, with a bronze $
* Quoted strings are red
* Operators are bronze
* Custom functions are white with purple parentheses
* HEREDOC is white, with the exception of variables (as described above)

How can I edit these .vim files to tweak colors. Where are colors defined?

if you want to try out all the colorschemes on your system you can
do so pretty quickly and easily, with the following keystrokes:
1. Esc
2. (type) :colorscheme
3. space
4. tab through the available colorschemes

[This example assumes your version is 6.3 and it's a default
installation. YMMV. -DPB]
Color schemes and themes are in:
/usr/share/vim/vim63/colors/
Syntax highlighting definition files are in:
/usr/share/vim/vim63/syntax/
To edit the PHP syntax highlighting definition file, open:
/usr/share/vim/vim63/syntax/php.vim
In there, you'll find lines such as this:
syn keyword phpFunctions utf8_decode utf8_encode
xml_error_string xml_get_current_byte_index
xml_get_current_column_number xml_get_current_line_number
xml_get_error_code xml_parse_into_struct xml_parse
xml_parser_create_ns xml_parser_create xml_parser_free
xml_parser_get_option xml_parser_set_option
xml_set_character_data_handler xml_set_default_handler
xml_set_element_handler xml_set_end_namespace_decl_handler
xml_set_external_entity_ref_handler xml_set_notation_decl_handler
xml_set_object xml_set_processing_instruction_handler
xml_set_start_namespace_decl_handler
xml_set_unparsed_entity_decl_handler contained
Those define how each string (keyword) should be classified. In
the above example, `xml_parso_into_struct` would be classified as
`phpFunctions`. Further down, you'll see lines like these:
HiLink phpStringDouble String
HiLink phpNumber Number
HiLink phpFloat Float
HiLink phpMethods Function
HiLink phpFunctions Function
HiLink phpBaselib Function
Notice that `phpFunctions` is an alias to `Function`.
Now check through the files in the themes directory, and you'll
see that (some) have colors and styles defined for Function (some are
re-aliased as `Identifier`, if memory serves correctly). Take a few
hints from those files, and you should be able to write your own from
scratch.

You're welcome, but try to keep non-PHP-related questions on their
respective lists. This one is really only for PHP questions, I just
thought that particular question and answer would benefit the PHP
developer community in the archives.

I noticed my script at http://onlinewebcheck.com was sometimes (fairly
often) failing to open some URLs that users have entered. fopen() returns
false very quickly, but when tried again with the same URL, sometimes it
works. What would cause this behavior? Why does fopen() occasionally fail to
open valid http addresses but works at other times?

Are the URLs being passed to fopen() properly escaped? Are they
valid, complete with http:// placed before the domain? Try keeping a
log of all URLs entered for a bit, and see which ones fail.

It's not the URL because the same URL will not work one time but will work
another time.
What needs to be escaped for a URL anyway? I am just changing spaces to
'%20' now.
I will try upgrading to 5.2.5. I'm using 5.2.3 now.
Thanks,

Some additional info. It seems I am getting these warnings when it fails:
Warning: fopen() [function.fopen]: php_network_getaddresses: getaddrinfo
failed: Name or service not known
Warning: fopen(http://wanganda2u.co.uk) [function.fopen]: failed to open
stream:
Now I have to find out why that is failing some of the time but not other
times.

Arbitrary code can still be injected unless it's properly
sanitized, but that's beyond the scope here.
Mainly, make sure quotes (single and double) are being converted.

That sounds like a DNS resolution error. If you have Telnet/SSH
or local console access, try doing a dig, traceroute, and ping series
on it.

Hi Daniel,
Yes, I have SSH access. I will keep that in mind. Upgrading to 5.2.5 may
have addressed this issue though. If not, then I'll concentrate on a
possible DNS resolution problem.
