[PHP] Confused overSimple PHP mySQL date question
Hi, I have checked the recent list archives and looked up various PHP functions. I know what I want should be simple but, apparently not simple enought for me. I have a mysql database that has a date field and a time field. I want users to be able to enter a date and a time in text boxes on an html form and have them end up in the database. I am having no trouble connecting to the database and running queries against the database but I cannot get the dates and times into the database. Of course I also want to search for the database for an entered date on another form. I am not having trouble with SQL statements or mysql_connect() or anything like that just taking a date as a string from a text box and getting into a DATE field in a mysql database. What obvuios thing did I miss? Note I am not using the system date or time stamp, these are entered dates.

This will make your script consume lots of memory, and is very
inefficient.
You'd be better of using the unix tail command:
$fp = popen(/usr/bin/tail -$limit $file, 'r');
if (! $fp ) {
echo 'unable to pipe command';
}
while (!feof($fp) ) {
$line = fgets($fp);
print $line;
}
Of course if you're simply going to output the results a simple:
system(/usr/bin/tail -$limit $file);
Would do the job nicely.

I've changed my script to the following:
?php
$file =/var/log/radius.log;
$fp = popen(/usr/bin/tail -$limit $file, 'r');
if (! $fp ) {
echo 'unable to pipe command';
}
while (!feof($fp) ) {
$line = fgets($fp);
print $line;
}
?
And now get the following errors:
Warning: Wrong parameter count for fgets() in /var/www/html/logs2.php on
line 10
I get this over and over and over (like it's producing the error once per
line in the log file).
Thanks,

prior to PHP 4.2 you had to use a second parameter for fgets. This

$line = fget($fp,4096);
will probably work.

I am jumping in late so I might have missed it. What is $limit set
too? is it set to 30?
I actually don't have limit set anywhere - I added:
$limit=30;
directly under $file = ... and got exactly what I need.
Thanks for all the help!

[PHP] mailing forms and input into MySQL
Hi all, I have a current php script that allows me to add/remove customer information from a particular MySQL Database. What I would like to do, is when an employee adds a customer, have some (if not all) of that information e-mailed to a particular e-mail address. I've created scripts that e-mail info, and ones that just enter info into a database, but have not attempted combining them. Anyone have any ideas, or is anyone doing this? If so, could you give me a quick how-to or point me in the direction of some online documentation? Thanks, Scott Miller
