<h2>PHPMailer FAQ</h2> |

<li><b style="background-color: #FFFF00">Q:</b> <b>I'm using the SMTP mailer and I keep on getting a timeout message |
|
well before the X seconds I set it for. What gives?</b><br /> |
|
<b style="background-color: #FFFF00">A:</b> PHP versions 4.0.4pl1 and earlier have a bug in which sockets timeout |
|
early. You can fix this by re-compiling PHP 4.0.4pl1 with this fix: |
|
<a href="timeoutfix.diff">timeoutfix.diff</a>. Otherwise you can wait for the new PHP release.<br /><br /></li> |
|
|
|
<li><b style="background-color: #FFFF00">Q:</b> <b>I am concerned that using include files will take up too much |
|
processing time on my computer. How can I make it run faster?</b><br /> |
|
<b style="background-color: #FFFF00">A:</b> PHP by itself is very fast. Much faster than ASP or JSP running on |
|
the same type of server. This is because it has very little overhead compared |
|
to its competitors and it pre-compiles all of |
|
its code before it runs each script (in PHP4). However, all of |
|
this compiling and re-compiling can take up a lot of valuable |
|
computer resources. However, there are programs out there that compile |
|
PHP code and store it in memory (or on mmaped files) to reduce the |
|
processing immensely. Two of these: <a href="http://apc.communityconnect.com">APC |
|
(Alternative PHP Cache)</a> and <a href="http://bwcache.bware.it/index.htm">Afterburner</a> |
|
(<a href="http://www.mm4.de/php4win/mod_php4_win32/">Win32 download</a>) |
|
are excellent free tools that do just this. If you have the money |
|
you might also try <a href="http://www.zend.com">Zend Cache</a>, it is |
|
even faster than the open source varieties. All of these tools make your |
|
scripts run faster while also reducing the load on your server. I have tried |
|
them myself and they are quite stable too.<br /><br /></li> |
|
|
|
<li><b style="background-color: #FFFF00">Q:</b> <b>What mailer gives me the best performance?</b><br /> |
|
<b style="background-color: #FFFF00">A:</b> On a single machine the <b>sendmail (or Qmail)</b> is fastest overall. |
|
Next fastest is mail() to give you the best performance. Both do not have the overhead of SMTP. |
|
If you have you have your mail server on a another machine then |
|
SMTP is your only option, but you do get the benefit of redundant mail servers.<br /> |
|
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> |
|
|
|
<li><b style="background-color: #FFFF00">Q:</b> <b>When I try to attach a file with on my server I get a |
|
"Could not find {file} on filesystem error". Why is this?</b><br /> |
|
<b style="background-color: #FFFF00">A:</b> If you are using a Unix machine this is probably because the user |
|
running your web server does not have read access to the directory in question. If you are using Windows, |
|
then the problem probably is that you have used single backslashes to denote directories (\). |
|
A single backslash has a special meaning to PHP so these are not |
|
valid. Instead use double backslashes ("\\") or a single forward |
|
slash ("/").<br /><br /></li> |
