Do you have long lines? If not try this:
$file = "error_log.txt";
if (($fp = fopen($file,'r+') !== 0)
{
// Increment the 1024 sufficiently to read enough data, fgets
automatically stops at \n
while ($line = fgets($fp,1024))
{
if ($line != "") echo($line."<br>");
}
}
Alternatively, do you know what the last char or the first char in each
line is? (i.e. an end-of-record or start-of-record identifier)
Try this:
$file = "errors.txt";
$file_size = filesize($file);
$byte_count = 0;
$fp = fopen($file,"r+");
$last_char = "";
while ($byte_count < $file_size)
{
$chr = "";
$eol = "";
$line = $last_char;
while ($eol == 0)
{
//Use this for EOR checking, replace the $EOR with your EOL/EOR char)
if (($chr = fread($fp,1)) === 0 || $chr == $EOR) $eol = 1;
else $line .= $chr;
/** Use this for SOR checking
if (($chr = fread($fp,1)) === 0 || $chr == $SOR) $eol = 1;
else $line .= $chr;
$last_char = $chr
**/
$byte_count = $byte_count + 1;
}
if (trim($line) != "")
{
//Do Something
echo($line."<br>");
}
}
this will need to be modified if you have a multi-byte EOR/SOR, but
hopefully this will give you a good base.
