extract info from another web page - php

Question

I have this test.php where i have this info :
callername1 : 'Fernando Verdasco1'
callername2 : 'Fernando Verdasco2'
callername3 : 'Fernando Verdasco3'
callername4 : 'Fernando Verdasco4'
callername5 : 'Fernando Verdasco5'
this page automatically changes that name every 10 min
In this another page test1.php
I need a php code that takes only the name of the callername3 and echo'it
Fernando Verdasco3
I've tried this like so test1.php?id=callername3
<?php
$Text=file_get_contents("test.php");
if(isset($_GET["id"])){
$id = $_GET["id"];
parse_str($Text,$data);
echo $data[$id];
} else {
echo "";
}
?>
but no result.
Is there any other option?
If i have "=" instade of ":"
callername1 = 'Fernando Verdasco1'
callername2 = 'Fernando Verdasco2'
callername3 = 'Fernando Verdasco3'
callername4 = 'Fernando Verdasco4'
callername5 = 'Fernando Verdasco5'
And i use This php Code it works
<?php
$Text=file_get_contents("test.php")
;preg_match_all('/callername3=\'([^\']+)\'/',$Text,$Match);
$fid=$Match[1][0];
echo $fid;
?>
i need this to work with ":"
Help?

Answer 1

You should store data in a file with the .php extension, since it's not executable PHP. I looks like you're going for the JSON syntax.
Since you need it to work with ':' I assume, for whatever reason, you can't change the format. Your example with '=' works because of the regexp:
preg_match_all('/callername3=\'([^\']+)\'/',$Text,$Match);
This says, match text like callername3= followed by a ' followed by one or more chars that are not a ' followed by a final '. Everything between the 's is stored in $Match[1][0] (if there were more parts in brackets they be stored in $Match[2][0], etc).
Your example doesn't work since it doesn't account for the spaces before and after the = sign. But we can fix that up and change it to work for : like this:
preg_match('/callername3\s*:\s*\'([^\']+)\'/',$Text,$Match);
echo $Match[1] ."\n";
This displays:
Fernando Verdasco3
And what that regular expression is match text that start callername3 followed by any amount of whitespace (that's the \s*) followed by a :, followed by any amount of whitespace, followed by a name in quotes (that is stored in $Match[1], this is the area of the regular expression enclosed in parenthesis).
I've also used just preg_match because it looks like you only need to match one example.

There is a rather simple approach to tihs:
$fData = file_get_contents("test.php");
$lines = explode("\n", $fData);
foreach($lines as $line) {
$t = explode(":", $line);
echo trim($t[1]); // This will give you the name
}
