I've use this in test.php?id=name2
$Text=file_get_contents("./name.txt");
if(isset($_GET["id"])){
$id = $_GET["id"];
$regex = "/".$id."=\'([^\']+)\'/";
preg_match_all($regex,$Text,$Match);
$fid=$Match[1][0];
echo $fid;
} else {
echo "";
}
The result should be George ,
how do i change this to work??
Mabe is another way to do this more simply?

Answer 1

$file=file('name.txt');
$id = $_GET["id"];
$result=explode(':',$file[$id-1]);
echo $result[1];
Edit: $result[1] if you want just name.

Answer 2

Heres an ugly solution to your problem, which you can loop trough.
And Here's a reference to the explode function.
<?php
$text = '"name1":"Robert"
"name2":"George"
"name3":"Flophin"
"name4":"Fred"';
$x = explode("\n", $text);
$x = explode(':', $x[1]);
echo $x[1];

Answer 3

Load the text file into an array; see Text Files and Arrays in PHP as an example.
Once the array is loaded you can reference the array value directly, e.g. $fid = $myArray['name' . $id]. Please refer to PHP how to get value from array if key is in a variable as an example.
