This is the expected behavior. It conforms to alteast the C-libraries on Linux, Win32 
and Solaris.

If a string contains two delimiters side by side (i.e. an empty field), strtok() 
treats the double delimiter as a single one and the results are shifted into the wrong 
variable. The previous version of the bug kept the second delimiter in the value 
returned by the function. This version does not, but it returns the wrong substring.

PHP version is 4.2.0-dev

(how do I report the correct version on the report form? Shouldn't there be at least a 
"other"?)

Example of the bug:
  
$String= "field1|field2||field4";

$Item1=strtok($String,"|");// $Item1: field1
$Item2=strtok("|");   // $Item2: field2
$Item3=strtok("|");// $Item3: field4
$Item4=strtok("|");// $Item4 is empty

compare the outputs of:

http://www.pierrejelenc.com/PHP/test-module.php(correct)
and
http://www.web-ho.com/PHP/test-module.php(incorrect)

Not at all. Mysql dump is poor man's database replication scheme :) I'd like
to run the database locally to get faster response times and to experiment
with some full-text search software. Are there any easier way to do this?

[PHP-DEV] Re: PGSQL async query functions and other utility functions

I would like to hear from Jouni and Zeev how you think about
async qeury and how it should be implemented.

I didn't want to touch existing code as much as possible. I'll fix
issues, such as clean up garbeges with async functions, later on
when design is fixed :) It does not change existing code.
Therefore, it's safe to apply to pgsql module to see how it can be
useful. (Benchmark result is exellent even without async connect
function) I would like to add features step by step so that I can
get feedback one by one, but if you prefer to commit it at once, I
can do that, too.

If nobody is working for async qeury now, I'll implement it
includingfail safe garbage handling, proper warnings, etc before
4.2.0RC hopefully.

What do you think?

[PHP-DEV] Bug #13996: Java crashing HTTP session

[kyle]

From: [EMAIL PROTECTED]
Operating system: RedHat 6.2
PHP version:  4.0.6
PHP Bug Type: Java related
Bug description:  Java crashing HTTP session

Whenever I execute any Java code inside of PHP (even simple things), the
HTTP session crashes and nothing is logged by Apache.


System Info:
RedHat 6.2
Apache 1.3.19
PHP 4.0.6
Sun JDK 1.3.1

PHP compile string:
'--with-apxs=/usr/local/psa/apache/bin/apxs'
'--prefix=/usr/local/psa/apache' '--with-mysql=/usr/local/psa/mysql'
'--with-system-regex' '--without-gd' '--without-pear' '--with-imap=/usr'
'--with-kerberos=/usr/kerberos' '--with-java=/usr/local/j2sdk-1_3_1'
'--without-imap-ssl' '--enable-sockets'
'--with-config-file-path=/usr/local/psa/apache/conf'

[Java] section of php.inijava.class.path
=/usr/local/psa/apache/lib/php/php_java.jar:/usr/local/jdk1.3/lib/tools.jar:/usr/local/jdk1.3/lib/dt.jar/usr/local/psa/apache/lib/php/php_java.jar:/usr/local/jdk1.3/lib/tools.jar:/usr/local/jdk1.3/lib/dt.jar
java.home =/usr/local/jdk1.3/jre/usr/local/jdk1.3/jre java.library

PHP code:

 
 getProperty('java.version').' ';
  print 'Java vendor=' .$system->getProperty('java.vendor').'  ';
  print 'OS='.$system->getProperty('os.name').' '.
  $system->getProperty('os.version').' on '.
  $system->getProperty('os.arch').' ';

  // java.util.Date example
  $formatter = new Java('java.text.SimpleDateFormat',
",  dd,  'at' h:mm:ss a ");

  print $formatter->format(new Java('java.util.Date'));
?>

Now, this runs fine from the command line:

/usr/local/psa/apache/bin/php
/usr/local/plesk/apache/vhosts/dominiopropio.net/httpdocs/test.php
X-Powered-By: PHP/4.0.6
Content-type: text/html
 
Java version=1.3.1_01 Java vendor=Sun Microsystems Inc.  OS=Linux
2.2.16-3 on i386 Thursday, November 08, 2001 at 11:38:51 PM Eastern
Standard Time

But when run through the browser it sits, and then stops loading with no
error either in the browser or apache logs.  Via telnet, the following
happens:

Escape character is '^]'.
GET /test.php
Connection closed by foreign host.

The HTTP connection is dropped instantly when the page is requested. 
Normal PHP runs fine.  If you need any other info please let me know.

No objection to discourage use of  PHP is pretty good at being self documenting, one of the aims of

Re: [PHP-DEV] WDDX recordset deserialize

[phillip]

I have attatched a patch to do recordset, datetime, and field tags processing
during deserialization.
