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.

[PHP] PHP installation
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

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

[PHP] REGEX: grouping of alternative patterns
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: $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 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It's not lazy. Given alternate matching subpatterns, the pcre engine choses the leftmost pattern, not the longest. For instance: Array ( [0] => a ) This isn't what you'd expect if you were familiar with POSIX regular expressions, but matches Perl's behaviour. Because each of your subpatterns can match an empty string, the lefthand subpattern always matches and the righthand subpattern might as well not be there. The simplest solution, if you don't want to completely rethink your regexp might be to replace \s with [[:space:]], remove the delimiters and the i modifier and just use eregi(). like so: $pattern = '[[:space:]]*(`?.+`?)[[:space:]]*int[[:space:]]*(\(([0-9]+)\))?[[:space:]]*(unsigned)?[[:space:]]*(((auto_increment)?[[:space:]]*(primary[[:space:]]*key)?)|((not[[:space:]]*null)?[[:space:]]*(default[[:space:]]*(`.*`|[0-9]*)?)?))[[:space:]]*'; eregi($pattern, $column1, $matches); print_r($matches); // match eregi($pattern, $column2, $matches); print_r($matches); // match -robin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Besides, the set of fictitious companies that support PHP4 and the set of fictitious companies that support PHP5 probably intersect to a large extent. In fact, I researched the matter thoroughly a couple of minutes ago and found that 108,064 companies support both versions of PHP, so there's only a total of 187,271 PHP hosting companies.

Prepared statements are inherently more secure than doing your own escaping. Thus, given the bad rap that PHP had for years on the security front, encouraging the use of prepared statements is up there with discouraging the use of register_globals. The sooner you convince new PHP programmers to do things in a naturally more secure way, the fewer bugs they will accidentally introduce later. (And I say more secure because nothing is 100% secure for you without effort; prepared statements and the filter extension just make it a lot easier to write secure code.) -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it." -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
