[Resolved] explode url to search text file

[rayzun]

i am trying to query a text file
here is my query:

url of page
abc.1352.html?&db_id=1352

<?
$lines = file('/home/yo2015/public_html/data/abc.data');
foreach ($lines as $line) {
$parts = explode('|', $line);
if ($parts[0] == $_GET['db_id']) {
echo "$parts[50] $parts[51], $parts[28], $parts[26], $parts[15], $parts[16] ";
}}
?>

this works ok, what Im trying to get to is querying by striping the page file name,
to replace the need to input the &db_id=1352 into the end of the url.

What I have to work with is
abc.1352.html

This is what Ive come up with - Im just a newbee

<?php $agent = $_SERVER["REQUEST_URI"];
$agent = str_replace (".html", "", $agent);
$agent = str_replace ("abc", "", $agent);
print("$agent"); ?>

$lines = file('/home/yo2015/public_html/data/abc.data');
foreach ($lines as $line) {
$parts = explode('|', $line);
if ($parts[0] == $_GET['$agent']) {
echo "$parts[50] $parts[51], $parts[28], $parts[26], $parts[15], $parts[16] ";
}}
?>

use POST method than GET method to remove &db_id=1352 from URL. Create a hidden input field in HTML with db_id value use POST method to send that db_id

[rayzun]

for the reply to my question - please xplain how to send the
db_id to my script?

the exact url:
domain.com/abc.1352.html

Im striping the extra parts like the".html", "abc"
which only leaves the number "1352".
The number "1352" is my search criteria for this line:
if ($parts[0] == $GET['db_id']) {
is it possible to get this result:
if ($parts[0] == $GET[' 1352 ']) {

<?php
$agent = $_SERVER["REQUEST_URI"];
$agent = str_replace (".html", "", $agent);
$agent = str_replace ("abc", "", $agent);

--not sure how to do this part

$agent = db_id ;

$lines = file('/home/cgi-bin/cs/data/car.data');
foreach ($lines as $line) {
$parts = explode('|', $line);
if ($parts[0] == $_POST['db_id']) {
echo "$parts[50] $parts[51], $parts[28], $parts[26], $parts[15], $parts[16] ";
}}
?>
