Hi, all.
Been staring at this for a couple of hours now and I find myself
completely bewildered. I suppose it doesn't help that I'm a php newbie.
Nevertheless, I throw myself at your mercy.
I have an array which I am attempting to split off into a new array.
The first array is just a whole bunch of links like so: http://www.example.com/query?track=h...m/whatever.php http://www.example.com/query?track=h.../whatever1.php
I managed to (sorta) successfully extract things out using preg_split:
foreach ($http_array as $i) {
$split = preg_split("/=/", $i, 2);
print "$split[1]<br>";
}
and the output looks like http://www.somewhereelse.com/whatever.php http://www.somewhereelse.com/whatever1.php
.... and so on...
The main goal is to parse an array much like the first bit at the top,
lop off anything after the first "=" in the line and then place it all
into another blank array so that I might do something else clever
elsewhere with it.
however, i've been totally unsuccessful in cleaning out blank entries
in the array (some creep in there, PREG_SPLIT_NO_E MPTY does not seem to
catch them) and cramming all of that into another new array. Been back
and forth between google and the fine php documents with little to show
for it.
eh. I give up. thoughts?

PREG_SPLIT_NO_E MPTY doesn't work for you, because your error_reporting level
is set too low.
If you would prepend the following to your code, you will see a warning when
the split didn't succeed:
error_reporting (E_ALL);
As you will see, $split[1] isn't always set and doing an isset($split[1]) or
a count($split[1]) test before populating the target array helps to skip
empty elements.
As an alternative, you can also use preg_match to test for matches:
foreach ($http_array as $i) {
if (preg_match("/=(.+)/", $i, $split)) {
print "$split[1]<br>";
}
}

<?php
//$http_array is already getting filled up somewhere else
$urls_array = array();
foreach($http_a rray as $i){
#Break the line into two parts, saving the stuff after "track="
list($junk, $url) = split('track=', trim(rtrim($i)) );
#Make sure $url contains a value
if(!empty($url) ){
#See if $url is already in the $urls_array array
if(!in_array($u rl, $urls_array)){
#It's not, so let's add it
array_push($url s_array, $url);
}
}
}
?>
Now you have a new array, $urls_array, which contains the URLs you want
to work some magic on.

Not a very good example, because:
1. Using split instead of explode creates a lot of overhead
2. You will get a warning when $i cannot be split into 2 elements and the
error reporting level is set to E_ALL

Cheers, Senator. Worked the first time. The comments were helpful as
well in helping me figure out exactly what was going on.
I appreciate the help

One of the larger tables in our database is now 6.8 million rows (1 per
