| 21 | <li><b style="background-color: #FFFF00">Q:</b> <b>I'm using the SMTP mailer and I keep on getting a timeout message
|
|---|
| 22 | well before the X seconds I set it for. What gives?</b><br />
|
|---|
| 23 | <b style="background-color: #FFFF00">A:</b> PHP versions 4.0.4pl1 and earlier have a bug in which sockets timeout
|
|---|
| 24 | early. You can fix this by re-compiling PHP 4.0.4pl1 with this fix:
|
|---|
| 25 | <a href="timeoutfix.diff">timeoutfix.diff</a>. Otherwise you can wait for the new PHP release.<br /><br /></li>

| 27 | <li><b style="background-color: #FFFF00">Q:</b> <b>I am concerned that using include files will take up too much
|
|---|
| 28 | processing time on my computer. How can I make it run faster?</b><br />
|
|---|
| 29 | <b style="background-color: #FFFF00">A:</b> PHP by itself is very fast. Much faster than ASP or JSP running on
|
|---|
| 30 | the same type of server. This is because it has very little overhead compared
|
|---|
| 31 | to its competitors and it pre-compiles all of
|
|---|
| 32 | its code before it runs each script (in PHP4). However, all of
|
|---|
| 33 | this compiling and re-compiling can take up a lot of valuable
|
|---|
| 34 | computer resources. However, there are programs out there that compile
|
|---|
| 35 | PHP code and store it in memory (or on mmaped files) to reduce the
|
|---|
| 36 | processing immensely. Two of these: <a href="http://apc.communityconnect.com">APC
|
|---|
| 37 | (Alternative PHP Cache)</a> and <a href="http://bwcache.bware.it/index.htm">Afterburner</a>
|
|---|
| 38 | (<a href="http://www.mm4.de/php4win/mod_php4_win32/">Win32 download</a>)
|
|---|
| 39 | are excellent free tools that do just this. If you have the money
|
|---|
| 40 | you might also try <a href="http://www.zend.com">Zend Cache</a>, it is
|
|---|
| 41 | even faster than the open source varieties. All of these tools make your
|
|---|
| 42 | scripts run faster while also reducing the load on your server. I have tried
|
|---|
| 43 | them myself and they are quite stable too.<br /><br /></li>

|
|---|
| 45 | <li><b style="background-color: #FFFF00">Q:</b> <b>What mailer gives me the best performance?</b><br />
|
|---|
| 46 | <b style="background-color: #FFFF00">A:</b> On a single machine the <b>sendmail (or Qmail)</b> is fastest overall.
|
|---|
| 47 | Next fastest is mail() to give you the best performance. Both do not have the overhead of SMTP.
|
|---|
| 48 | If you have you have your mail server on a another machine then
|
|---|
| 49 | SMTP is your only option, but you do get the benefit of redundant mail servers.<br />
|
|---|
| 50 | If you are running a mailing list with thousands of names, the fastest mailers in order are: SMTP, sendmail (or Qmail), mail().<br /><br /></li>
|
|---|
| 51 |
|
|---|
| 52 | <li><b style="background-color: #FFFF00">Q:</b> <b>When I try to attach a file with on my server I get a
|
|---|
| 53 | "Could not find {file} on filesystem error". Why is this?</b><br />
|
|---|
| 54 | <b style="background-color: #FFFF00">A:</b> If you are using a Unix machine this is probably because the user
|
|---|
| 55 | running your web server does not have read access to the directory in question. If you are using Windows,
|
|---|
| 56 | then the problem probably is that you have used single backslashes to denote directories (\).
|
|---|
| 57 | A single backslash has a special meaning to PHP so these are not
|
|---|
| 58 | valid. Instead use double backslashes ("\\") or a single forward
|
|---|
| 59 | slash ("/").<br /><br /></li>
