Did you see the mega thread that started from someone asking about PHP 4
classes? :-)
Personally I've already written off PHP 4 support, and assume that people have
PHP 5. I have access to only one box that is older than PHP 5.2.0, and
that's a 5.1.6 box.
Here's a bigger question: When will people stop using mysql_ as their example
API, when PDO is more standard in PHP 5 and more secure, and mysqli is
available as well?

As always, the key question must be - what's the advantage of moving?
When the developer benefits from something being "more standard" and
more secure, then he'll change.
If you want to force someone to change, you remove the interface (after
having marked it deprecated for a while).

Well, I didn't. I just provided a silly answer to an impossible
question. There is no way anyone could possibly come up with a
remotely accurate number of how many hosters have this or that. So I
made the numbers up. $RANDOM.

300,000 is probably a lot, yes. Still, Switzerland alone has roughly
335.000 companies. About 400 of those are members of a Swiss
association for ISPs, but there's probably another couple of hundred
that aren't. Extrapolating from e.g. 500 webhosters for a population
of 7million, that would make roughly 35,000 in the EU (pop. 480mill).

I'm having difficulty compiling and upgrading to version 5.2.4. Also using
WebSTAR.
Here's the steps I took and the resulting errors.
Any help would be appreciated!
1. Download the latest copy of PHP source code from [ http://www.php.net/
]http://www.php.net
2. Open the Terminal application (in Applications/Utilities).
3. Type in "cd " and then drag the PHP source folder from the Finder to the
Terminal.
4. Click back in the Terminal and hit return. This should put you in the PHP
source folder.
5. Type in "./configure" and hit return. If you get a "command unknown"
error, type in "sudo chmod a+rx configure" and retry. Wait for the script to
complete.
6. Type in "make" and hit return/enter. Wait for the compile to complete.
Results, no compiled php to copy to!

It's available in 4.3.10 as well, but manual doesn't specify what it
defines - I suppose I can echo or vardump it to find out. Also manual
doesn't mention "cross-platform", in any case even if it
is "cross-platform" it seems pointless because how does PHP know which
environment the output is going to be used in? I
define 'CR', 'LF', 'CRLF' and use them as circumstances dictate.

youre right about that; my mistake.
but manual doesn't specify what it
> defines -
let the source tell it:
phpunpack/php5.2-200708051230/NEWS:2867:- Added PHP_EOL constant that
contains the OS way of representing newlines.
47 #ifdef PHP_WIN32
48 #include "tsrm_win32.h"
49 #include "win95nt.h"
50 # ifdef PHP_EXPORTS
51 # define PHPAPI __declspec(dllexport)
52 # else
53 # define PHPAPI __declspec(dllimport)
54 # endif
55 #define PHP_DIR_SEPARATOR '\\'
56 #define PHP_EOL "\r\n"
57 #else
58 #define PHPAPI
59 #define THREAD_LS
60 #define PHP_DIR_SEPARATOR '/'
61 #if defined(__MacOSX__)
62 #define PHP_EOL "\r"
63 #else
64 #define PHP_EOL "\n"
65 #endif
66 #endif
I suppose I can echo or vardump it to find out.
a little trickier than you might guess :
php > var_dump(PHP_EOL);
string(1) "
"
Also manual

its supposed to be used for the command line;
theoretically the output will land on the same system from which its
generated.
however, coming from my linux box; this was correctly interpreted by
internet explorer
<?php
echo 'blah' . PHP_EOL . 'blah';
?>
result when viewing source was
blah
blah
I define 'CR', 'LF', 'CRLF' and use them as circumstances dictate.
the use of that definitely depends upon the circumstances; ill stick w/ the
predefined constant until i run into a problem ;)

$mit and $mire are arrays. $mit contains all the patterns, they all
start and end with /
$mire contains all the replacements.

ereg_replace cannot take arrays as arguments...
htmlentities might work but then all my patterns containing < or > has
to be modified - and then it might replace strings which I don't want to
get replaced. e.g. <script> might be a legal string which I don't
want to replace, but I want to replace <script>

Hi,
Is there a built in function in PHP5 to determine if an integer is even or
odd?

How about :
if ($IntegerValue % 2) {
// odd
} else {
// even

Hi,
Trying to install PHP, however it's failing with the following:
Configuring extensions
checking whether to enable LIBXML support... yes
checking libxml2 install dir... /usr/lib64
checking for xml2-config path... /usr/bin/xml2-config
checking whether libxml build works... no
configure: error: build test failed. Please check the config.log for
details.
The following is in config.log:
configure:20028: checking whether libxml build works
configure:20055: gcc -o conftest -g -O2 conftest.c
-lresolv -lm -ldl -lnsl -lxml2 -lz -lm 1>&5
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status
configure: failed program was:
#line 20044 "configure"
#include "confdefs.h"
char xmlInitParser();
int main() {
xmlInitParser();
return 0;
}
If it helps, this is a bit of an `ls -l` of /usr/lib64:
libxml2.so -> libxml2.so.2.6.27
libxml2.so.2 -> libxml2.so.2.6.27
libxml2.so.2.6.19
libxml2.so.2.6.27
And this is what's at the end of my config.log:
configure:19793: checking whether to enable LIBXML support
configure:19841: checking libxml2 install dir
configure:19870: checking for xml2-config path
configure:20028: checking whether libxml build works
configure:20055: gcc -o conftest -g -O2 conftest.c
-lresolv -lm -ldl -lnsl -lxml2 -lz -lm 1>&5
/usr/bin/ld: cannot find -lz
collect2: ld returned 1 exit status
configure: failed program was:
#line 20044 "configure"
#include "confdefs.h"
char xmlInitParser();
int main() {
xmlInitParser();
return 0;
}
Thanks.

Looks like you need to install libz.
I installed various zlib and zlib-devel packages, but finally went with
an rpm, but when I run `apachectl configtest` I get this:
Cannot load /usr/lib64/httpd/modules/libphp5.so into server:
/usr/lib64/httpd/modules/libphp5.so: undefined symbol: apr_pool_cleanup_null
Umm help?

OK so now I'm back to compiling PHP after the ridiculous nightmare of
rpms. I checked /lib and have the following:

-rwxr-xr-x 1 root root 71744 Sep 21 19:23 /lib/libz.so.1.2.3
Is PHP looking for a different file?
Thanks.

Hey list,
I'm having problems with grouped alternative patterns.
The regex I would like to use, is the following:
/\s*(`?.+`?)\s*int\s*(\(([0-9]+)\))?\s*(unsigned)?\s*(((auto_increment)?\s*(primary\s*key)?)|((not\s*null)?\s*(default\s*(`.*`|[0-9]*)?)?))\s*/i
It matches this statement:
`id` INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY
But not this:
`test4` INT(11) UNSIGNED NOT NULL DEFAULT 5
However, if I switch the alternatives, the first statement doesn't
match, but the second does.
FYI: In both cases, the column name and data type are matched, as expected.
It appears to be doing lazy evaluation on the pattern, even though every
resource I can find states that every alternative is tried in turn until
a match is found.
Any ideas on how this can be resolved would be greatly appreciated.
Here is some code:
<?php
$pattern1 =
'/\s*(`?.+`?)\s*int\s*(\(([0-9]+)\))?\s*(unsigned)?\s*(((auto_increment)?\s*(primary\s*key)?)|((not\s*null)?\s*(default\s*(`.*`|[0-9]*)?)?))\s*/i';
$pattern2 =
'/\s*(`?.+`?)\s*int\s*(\(([0-9]+)\))?\s*(unsigned)?\s*(((not\s*null)?\s*(default\s*(`.*`|[0-9]*)?)?)|((auto_increment)?\s*(primary\s*key)?))\s*/i';
$column1 = '`id` INT(11) UNSIGNED AUTO_INCREMENT PRIMARY KEY';
$column2 = '`test4` INT(11) UNSIGNED NOT NULL DEFAULT 5';
$matches = array();
preg_match($pattern1, $column1, $matches); print_r($matches); // match
preg_match($pattern1, $column2, $matches); print_r($matches); // doesn't
match
preg_match($pattern2, $column1, $matches); print_r($matches); // doesn't
match
preg_match($pattern2, $column2, $matches); print_r($matches); // match
?>
Greetz,
Stijn
