Printing certain things from a file... not the entire thing.

[suttercain]

Hi Everyone,

 

I am running this code:

<?php
$lines = file('http://localhost/PHP%20Tutorials/By%20Example/examples/chapter10_examples/datebook.bck');

// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
   echo "<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}
?>

 

It is outputting the following:

I am trying to print only certain perimeters. Like let's say I want to only output only the November and December lines.

 

Is there an easy way to do this?

 

Thanks.

First I assume that your file looks like:

but your file extension "bck" is very weird...

code should be:

$data = "pathtofile";
foreach ($data as $line) {
$info = explode(" ", $line);
$max = count($info);
$date = $info[$max];
$date1 = strtotime($date);
$date2 = date('m', $date1);
if ($date2 == 11 or $date == 12) {$array[] = $info[0];}}
foreach ($array as $line1) {
echo $data[$line1];

The strtotime() function probably won't work here since it looks like the OP has years earlier than 1970 in the file.

 

BTW, there's nothing wrong with a file extension of ".bck". I assumed that it's a backup file of some sort.

It won't be too happy with a string like "94087:5/19/66:34200" either.

 

Also the index would be $max-1

 

try

<?php
$lines = file('http://localhost/PHP%20Tutorials/By%20Example/examples/chapter10_examples/datebook.bck');

foreach ($lines as $line_num => $line) {
    if (strpos($line, ':11/') || strpos($line, ':12/')) 
    echo "<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}

?>
