Hey Techs,
Have a question for you.
Am building a system [using PHP] where a users Long URL is saved table-side at registration. Need to echo a short link on page both for encoding and sizing reasons.
Have been able to generate a string of characters (8) to use as the "short link" but when I tried to use a pre_replace to swap the Long URL for the Short URL I received a delimiter/alphanumeric character error.
Any idea how to fix this or an alternative solution. Thanks in advance. James.
Just some thoughts...
Sometimes the compiler is a wuss and it's not the programmer's fault. I've solved that problem in the past by:
1. De-nesting.
2. Using a string of 2 or 3 simpler commands/functions to replace the single "stronger" command/function.
Para!
Right, I did the following:
$long="gitara.me/Artist/$ARTIST/";
function generateRandomString($length) {
$result = ''; for ($i = 0; $i < $length; $i++) {
$num = rand(48, 122); $result .= chr($num);} return $result;} $short=generateRandomString(8);
$shortlink=preg_replace($long,"",$short);
Have no idea why this delimiter error popped up. I checked php.co.uk but got noting back.

I'm not familiar with this language syntax, but I noticed that:
You have an odd number of " Do they need to be evenly paired?
Just a shot in the dark here.
No worries.
The syntax is PHP
The .= is used in place of a= a . b which is used to cluster elements of a string.
In this case, Part One is $result=''; or null.
Part two is $result .= chr($num) which returns is a string of random ASCII characters $num=rand() for~each instance where $result= null.
So, it states $result = null . chr($num) or $result .= chr($num)
The last bit assigns a total character output of (8).
The goal is create a readable shortlink, like bit.ly, fb.me, ow.ly or t.co and allow the visitor to use the shortlink to share the page. I worked out a temp solution which does this command at registration, and stores the shortlink in the database. At runtime, the shortlink is echoed on-page. But, this means loading another script to parse the URI when the domain is opened, and redirect to the true page else a custom 404. Ugh!
James.
ps, yes, magic quotes in PHP must always be paired, or it throws errors.
I truly am obsolete. But I'm fine with that.
