PHP - Reading Live Text Log ?

[jerryyang_la1@yahoo.com]

Hi

My mail server outputs live logs like this:

I'm looking to try and read this file via PHP and colourise each line
based on the connection ID displaying the final result in a php
page...

eg:

T 20070325 123318 4605007c Connection from 111.111.111.111
The ID is 4605007c This appears on 3 lines. Note that the ID's are
not always grouped together.

Can this be done ?? The file is live and constantly changing...

Thanks

Re: PHP - Reading Live Text Log ?

You could do this with tail and fread. Here's one example of reading a
file that's continuously being updated:

Re: PHP - Reading Live Text Log ?

Thanks

But what about colourising the matching lines ?

Here's one (ugly) way to do it:

<?

error_reporting (E_ALL);

function printLog($text)
{
$lines = explode("\n", $text);
$buf = '';
$head = null;
$extra = array();

for ($i = 0; $i < count($lines); $i++) {
$parts = explode(' ', $lines[$i], 5);
if (count($parts) >= 4 && ($parts[0] == 'T' || $parts[1] == 'E'))
{
if (!is_null($head )) {
$buf .= printEntry($hea d, $extra);
}
$head = $parts;
$extra = array();
if ($i == count($lines) - 1) {
$buf .= printEntry($hea d, $extra);
}
} else {
$extra[] = $lines[$i];
}
}

echo $buf;
flush();
}

function printEntry($hea d, $extra)
{
static $rnd = null;
if (is_null($rnd)) {
$rnd = rand();
}

$hex = md5($head[3] . $rnd);
$fg = substr($hex, 0, 6);
$bg = sprintf("%02x%0 2x%02x",
((('0x' . substr($hex, 0, 2)) + 0x7f) % 0xff),
((('0x' . substr($hex, 2, 2)) + 0x7f) % 0xff),
((('0x' . substr($hex, 4, 2)) + 0x7f) % 0xff));

$msg = join(' ', $head) . "\n" . join("\n", $extra);
$str = "<span style=\"width: 100%; color: #{$fg}; background: #{$bg};
\">" .
htmlentities($m sg, ENT_QUOTES) . "</span>";
$str = nl2br($str);

return $str;
}

$text = "T 20070325 123318 4605007c Connection from 111.111.111.111
