Re: [PHP] MySQL client version problem
Thing is, I have MySQL 5.0.67 installed, and I've never had MySQL 4 on this box (Xserve G5, Mac OS X Server 10.4.11). Here's my configure command: ./configure --prefix=/usr/local/php5 --mandir=/usr/share/man -- infodir=/usr/share/info --with-apxs --with-ldap=/usr --with-kerberos=/ usr --enable-cli --with-zlib-dir=/usr --with-libxml-dir=/usr --enable- exif --enable-ftp --enable-mbstring --enable-sockets --enable-fastcgi --with-iodbc=/usr --with-curl=/usr --with-config-file-path=/private/ etc --with-mysql=/usr --with-mysql-sock=/var/mysql/mysql.sock If I remove --mysql=/usr, MySQL doesn't work at all (not surprising I guess). Is there something else I need to do to compile PHP with the latest MySQL module? (Which I don't understand--is the module part of the PHP source, or is it something external that gets linked to?) ...Rene On 5-Jan-09, at 10:13 AM, c...@l-i-e.com wrote: PHP had a built-in MySQL for awhile as I recall.

[PHP] MySQL client version problem
After following some instructions on compiling PHP 5.2.8 from source ( http://osx.topicdesk.com/content/view/48/62/ ), I notice now that phpinfo() reports that I am running the MySQL client API version 4.1.22 (instead of 5.0.45).

[PHP] Regular expressions (regex) question for parsing
Hi, I'm looking for some ideas on the best way to parse blocks of text that is formatted such as: $sometext %\r\n -- good data $otherstring %\r\n -- good data $andyetmoretext %\r\n -- good data $finaltext -- bad data (missing ending) Each line should start with a $dollar sign, then some arbitrary text, ends with a percent sign, followed by carriage-return and line-feed. Sometimes though, the final line is not complete. In that case, I want to save those lines too. so that I end up with an array like: $result = array ( "matches" => array ( 0 => "$sometext %\r\n", 1 => "$otherstring %\r\n", 2 => "$andyetmoretext %\r\n" ), "non_matches" => array ( 3 => "$finaltext" ) ); The key thing here is that the line numbers are preserved and the non- matched lines are saved... Any ideas, what's the best way to go about this? Preg_matc, preg_split or something incorporating explode?

Nope, it's just http, port 80, and not to IIS.

[PHP] fread() behaviour
I'm trying to understand something about fread(). I'm using fread() on
an incoming socket stream that will send, for example, 26630 characters:
while ( ($buf=fread($read[$i], 8192)) != '' ) {
$sock_data .= $buf;
usleep(1000);
echo ".";
}
echo ",";
As soon as the socket client sends the data, immediately the server
will echo:
Then wait nearly a minute, and echo:
,
So my question is, why does fread wait if there is nothing more to
read? Shouldn't it return immediately? (That's what I want.) And as
for the delay, it's there so that if the incoming data is a little
slow, it has time to catch up with fread. Thanks.

[PHP] PHP Warning: HTTP request failed -- BSD resource limit reached?
Hi, I have four identical command-line PHP scripts running, and each will frequently fetch some data from another server via file_get_contents(). By frequently, I mean on average, every second. Periodically, one of the processes (command-line PHP scripts), will fail on file_get_contents(), with the error message: PHP Warning: file_get_contents(http://.../): failed to open stream: HTTP request failed! Sometimes it's a single failure, other times, it fails repeatedly for 30-60 seconds, then starts working again. Strange, no? At first, I thought maybe I've maxed out the server in question, but I'm not. This problem happens on both servers that the scripts fetch data from. And more significantly, while one process may fail at file_get_contents(), the other processes (running identical code) on the same box continue to execute the function (against the same servers) without incident. My question is, is there some resource in Mac OS X Server 10.4 (or PHP 5.2.4) that would limit a continuously running PHP script from executing file_get_contents()? And to be clear, the failure doesn't kill the script, and after the failure, it will start working again. ...Rene -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] htaccess and $PHP_AUTH_USER
Please, someone, help me... What I want to do: Have a user prompted for an ID/password, both of which (if valid), get passed to a PHP script, which then uses the ID/password to selectively display certain fields of a table. (For example, if the user logs in as "Sales", he would only see the sales-related fields of the tables. Whereas, if the user logs in as "Production", she would see the production-related fields. Pretty simple.) I've read the PHP docs on $PHP_AUTH_USER. One stupid question: Must I use the htaccess directory-protection feature of Apache in order for this to work (or is$PHP_AUTH_USER not dependent on Apache (or any web server) at all)? I mean, from reading the docs, it seems as if the value stored in $PHP_AUTH_USER comes what the user types into the Apache-spawned dialog box (when the user types the URL containing that password-protected directory.)?? The thing is, when I turn password protection on for the directory in question, and add the users and passwords to the htaccess file, then go to the URL in the browser, I get prompted several times for a user and password--first, it seems, by Apache, then by the PHP code I copied from the docs. If anyone can help, I'd greatly appreciate it. Best would be some real code running in a similar server environment.
