Hi,

Im looking for a function that allows me to get to the nest line of a file that is read if something is true eg…

[code=php]
 $fp = fopen($filename, “r”); //Open the server log
$content = fread($fp, filesize($filename)); // Read the server log
$content = explode(“n”, $content); // explode into array
$content = array_reverse($content ); // reverse the array

$a = 2;
if ($a <3 ‘then goto next line of file’){
then do some stuff in here}

else{}

[/code]

Can anyone help with this please??

Thanks. Eon201

@LuboxNov 08.2007 — fgets() perhaps, if I understand your question? Read about it in the manual here.

Example 623. Reading a file line by line:

[code=php]
<?php
$handle = @fopen("/tmp/inputfile.txt", "r");
if ($handle) {
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
echo $buffer;
}
fclose($handle);
}
?>
[/code]


Edit: or maybe the file() function? Here

$fp = fopen($filename, "r"); //Open the server log
$content = fread($fp, filesize($filename)); // Read the server log

$content = explode("n", $content); // explode into array

$content = array_reverse($content); // reverse the array

$a = 2;
$i=0;
if ($a < 3){
$i++;
// $content[$i] is now your next line in the file... so do something with it.
}
[/code]
