[PHP] Error: symbol _erealloc not found, PHP 4.0.6 under Solaris/Sparc
When trying to load Zend optimizer, the following error gets logged: Failed loading /var/www/lib/ZendOptimizer.so: ld.so.1: \ /opt/apache/bin/httpd: fatal: relocation error: file \ /var/www/lib/ZendOptimizer.so: symbol _erealloc: referenced \ symbol not found It seems from whatever little bits I could find on the Net, that the _erealloc symbol should be defined in the PHP itself. The PHP is installed as a module with Apache 1.3.22, compiled from sources, and is (otherwise) working perfectly fine. Any ideas on how to overcome this problem?

Re: [PHP] Using PHP + GD to make bar graphs?
While taking a university course I needed to ``squash the competition'' by hacking together quick bar-charts with PHP. These are not very sophisticated, but I liked my approach because they generate very little graphics (read: fast downloads), and when you roll a mouse over a bar, you get numeric value for it.

The code is rather trivial, though. They look very nice and usable...just the way i like 'em. I'd be interested in seeing the source code...you can reply directly to my email account if you like! are you using a graphic package like GD? or are you using the 'poor mans bar graph' method using tables and percentage widths? Each individual bar is generated with GD, and arranged in a table. The images are stored in subdirectory bars (should be writeable to Apache). Each bar is given a name like bar_NNN.png, where NNN is its height in pixels. If a bar of a given name already exists, it is not re-generated. I never intended to release the code, so it has some stuff hard-coded, like the number of columns and the colors, and not commented. Shouldn't be hard to change, though. Ideally the whole thing would be organised in a class. If anyone takes the time to rearrange the code, or improve it otherwise, I'd like to see the results (although you don't really have to). All functions are in a file barchart.inc: http://www.thpoon.com/408/barchart.inc.phps Example of using the functions are in this file: http://www.thpoon.com/408/barchart.phps Example input file is here: http://www.thpoon.com/408/sqattl.txt Have fun, -- Arcady Genkin i=1; while 1, hilb(i); i=i+1; end -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

[...] IMO, it makes more sense to use PHP's built in functions that can do the same, but YMMV. vrfy does appear to be a decent tool, my point was that when checking email addresses (not domains) most servers will deny the vrfy command and so it won't be very useful. In fact, I tried a number of different email addresses on different hosts and all reported Command Unimplemented. You are right, by default the proggie is not very useful. The -n option is probably of the most utility: -n Many non-sendmail hosts do not, or incorrectly or incompletely, implement the VRFY command. Other systems have VRFY or EXPN disabled for privacy reasons. This option uses an alternative protocol suite with the regular HELO, MAIL, RCPT and RSET commands. This gives only a global indication whether the recipient is valid. Recursive mode is not possible, and will be disabled. I've tried it with a number of email addresses, and it worked. Of course, this can be coded in the PHP script, but it would require elementary knowledge of SMTP protocol and more code to debug and maintain. For many people relying on an external utility like that may have more advantages. -- Arcady Genkin i=1; while 1, hilb(i); i=i+1; end -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Basically it wants to determine whether the mail exchanger would accept email for a given domain. In most cases it won't give you 100% certainty that the email addy is legit, but at least you know that the domain part is not faked, and there is a mail exchanger willing to serve it. -- Arcady Genkin i=1; while 1, hilb(i); i=i+1; end -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

According to the manual, or are not metacharacters, so no use
escaping them. In any case, your expression can be simlified somewhat
using Perl's \w sequence. Don't forget to designate beginning and end
of string. Try the following:
'/^\w[\w.-]*@([\w-]+\.)+\w{2,}$/i'

[PHP] PHP escapes shell commands for me?
PHP version 4.0.5 under: SunOS 5.8 Generic_108528-07 sun4u sparc SUNW,Ultra-Enterprise magic_quotes_gpc = On magic_quotes_runtime = Off It appears that PHP by default escapes arguments of any commands passed to exec() and friends (passthru(), popen()). As a result I am not able to pass an argument consisting of two tokens, separated by space, as one argument. Is this intended behavior? Is this inflicted by some option in php.ini? I have another server running FreeBSD with virtually identical php.ini file, and it doesn't exhibit such misbehavior.

[PHP] Email verification (was: [PHP] Removing Invalid Users)
Steve Werby [EMAIL PROTECTED] writes: Clayton Dukes [EMAIL PROTECTED] wrote: How can I write code that will search the database and check the validity of an email address, and if it's bad, to remove that entry from the database? Like Tom said, use regex to check the email is of a valid format. A small percentage of servers can be contacted to find whether an email address is valid, but fewer and fewer are allowing this so it's completely unreliable. There's a nifty little open source program called `vrfy' which does nice things about email veryfication. Finding it is left as an exercise to the interested (I found it in FreeBSD's ports). Excerpt from the man page: NAME vrfy - Verify electronic mail addresses SYNTAX vrfy [options] [-v] address [host] vrfy [options] [-v] -f [file] [host] vrfy [options] [-v] -p domain vrfy [options] [-v] -T domain [name] DESCRIPTION vrfy is a tool to verify electronic mail addresses. The only required parameter is the address to be verified. The actual verification will be carried out at the remote machine where mail to the given address would normally be delivered. This may be a mail exchange host and not the final destination host. If an explicit host is given as the second argument on the command line, the specified address is verified at that machine. The output of the program shows whether or not the address can be handled at the contacted host. Error messages will be printed if the address is invalid. If the address is recognized, the output shows the remote host's notion of the (possibly translated) address. If it represents a local user at that host, additional information about the user may be displayed. Note that if the address is accepted by the contacted host, but this is not the final destination host, one still cannot be sure that the address represents a valid recipient. It is a handy tool to verify local mail addresses. If you have set up a .forward file, you can verify your own address to check that the forwarding is done properly. If you specify an arbitrary name, you can check whether this resolves to any valid recipients. -- Arcady Genkin i=1; while 1, hilb(i); i=i+1; end -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Any ideas? does the directory exist? This is the same directory where Apache writes its own logs. It' only writeable to root, but I thought that the controlling apache process would be responsible for creating the file (controlling apache runs as root). does php or apache have the right to create new files in /var/www/logs/? if the file exists, are the permissions set correctly on it? keep in mind that the user that owns apache usually has very limited powers Well, see above. If Apache can write its own logs there, it should be able to write PHP's logs there too, right? What worries me is that the logs are directed into apache's error logs.
