[Resolved] Copy string

[eli03]

Greetings,

if i have something like this

$var="x_Amount=14.95&x_Card_Num=4111111111111111&x_Exp_Date=0101"

How do i get the "14.95", "4111111111111111", and "0101" ?

Thanks,

I believe you can split the string based upon whatever character: &.

Split the string, then read the values.

EDIT
http://us2.php.net/split

So, you would have to edit your variable so that it strips all the text, and leaves the & symbols.

So you create a list:

list($var1, $var2, $var3)

then, set it's values by splitting your other variable:

list($var1, $var2, $var3) = split('&', $var);

Then access your values by referring to the proper variable: $var1, $var2, $var3.

So:

<?php
$variable = "Brett.Patterson.January.13.2004";

list($fname, $lname, $mbirth, $fnum, $fyear) = split('.', $variable);

echo('First Name: '.$fname.'<br>');
echo('Last Name: '.$lname.'<br>');
echo('Birth Month: '.$mbirth.'<br>');
echo('Favorite Number: '.$fnum.'<br>');
echo('Favorite Year: '.$fyear.'<br>');
?>

Would end up outputting this:

First Name: Brett
Last Name: Patterson
Birth Month: January
Favorite Number: 13
Favorite Year: 2004

I hope this has helped you.

= ) how do i do that?

Edited my post for you.

I realized I didn't add any help for you. So look above and it's there now.

EDIT

Depending upon how you set that variable, it can be easy.

You can just set the splitting variable like "&" or "/".

or you can also set a multiple option so it splits it like:

split("x_Amount x_Card_Num x_Card_Exp", $var);

I think. Don't hold me to it.

Look at this page I just threw up there for more help:

http://bpatterson.net/test/split.php

It's source is all php...

<?php

$var = "14.95/1234567890123456=01-2000";
$var2 = "14.95/1234567890123456/01-2000";
echo("Original: ".$var."<br>"."\n");
list($amount, $cardNum, $expiration) = split('[/=]', $var);

echo('Amount: '.$amount.'<br>');
echo('Card Number: '.$cardNum.'<br>');
echo('Expiration: '.$expiration.'<br>');

echo('<hr>');

echo("Original: ".$var2."<br>"."\n");
list($amount2, $cardNum2, $expiration2) = split('/', $var2);

echo('Amount: '.$amount2.'<br>');
echo('Card Number: '.$cardNum2.'<br>');
echo('Expiration: '.$expiration2.'<br>');

?>

Hope I helped you.

Or, for a quicker answer to the original question, try [man]parse_str[/man]. That said, bpat1434's code is a lot more versatile ('xcept I prefer [man]preg_split[/man] if I need regular expressions, and [man]explode[/man] when I don't).

thanks all, I have a problem. here is the code, there is a problem on splitting the $result, it gives me this error:
/////////////////////////////////////////////////////////////////////////////////
//output of the script
|14.95|4111111111111111|0101
Warning: split(): REG_EMPTY: in \pathto\htdocs\findrep.php on line 7
amount =
ccnum =
expdate =
////////////////////////////////////////////////////////////////////////////////

<?
$var="x_Amount=14.95&x_Card_Num=4111111111111111&x_Exp_Date=0101";
$ser=array('x_Amount=','&x_Card_Num=','&x_Exp_Date=');
$repl=array("|","|","|");
$result = str_replace($ser, $repl, $var);
echo $result; //output |14.95|4111111111111111|0101

list($amount, $ccnum, $expdate) =split("|",$result); // produce error, this is line 7

echo "amount = ".$amount."<br/>";
echo "ccnum = ".$ccnum."<br/>";
echo "expdate = ".$expdate."<br/>";
?>

thanks

ok, thanks anyway, I used explode instead of split. it works fine =)
