[PHP] Array Search
Dear List - Here is a code snippet: $bla = array(g1 = $results[7][6], h1 = $results[7][7]); print_r($bla); $value = h1; $locate1 = array_search($value, $bla); echo This is locate ; print_r($locate1); if(in_array($value, $bla)) print_r($bla); Neither the array_search or the in_array functions give any results. I have tried it with both h1 and h1; $results[7][6] = Wn; $results[7][7] = Wr; This is a chess board where g1 and h1 are the coordinates and the results array contains the pieces at that coordinate. What am I doing wrong? Advice and comments please. Thanks. Ethan Rosenberg -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Array Search Problem
Hi,
At the time when I am writing this, looks like I already got the functions I
needed. It turned out that I had to use some array_combine, sorting the items
by keys instead of values as well as using array_keys to get the values I
needed.
Thanks for pointing me towards the right direction.

(almost) all the tricks are in the comments of the help page for a
function, on php.net
but all functions accept only a given (and usually documented) set of
parameter(type)s, so you'll probably have to prepare the var, or even
call the function in a loop, outputting to yet another descriptively
named array that'll be used as wanted list later in the code.

Yes, I found a recursive way to find out the index like I wanted, by
doing something like
$from = explode(-, $from);
$state_colors= explode(-, $state_colors);
$change = explode(-,$change);
$count = count($new_array);
$i=0;
foreach ($new_array as $key = $value){
echo $i . . $key . is . $value . miles awaybr /;
$i++;
}
You can see it is not very elegant, and plus, I created the $new_array so I
could do the ordering according to the values of the change array. I can
tell that since this is not a single array, which is probably why
array_search does not work.
Since I don't need the value of my new_array here, I am still finding
out how to strip off the values here without having to flatten my array.
Is what I am trying to do here possible? Or, is there a trick in
array_search that I could use to find the index without having to strip off
anything?
Thanks for your help.

[PHP] Array Search Not Working?
Hi,
I have two arrays here that I have combined into a new array, as shown here:
$from = explode(-, $from);
$change = explode(-,$change);
$new_array = array_combine($from,$change);
I then tried reading it from a file and do string matches, trying to find out
the key using the array_search of the individual array elements. I seem to
have no such luck, even when I copied one of the elements after I do a
print_r($new_array);
Here is the code,
foreach ($lines2 as $line_num = $line2) {
$style_line_num = $line_num+3;
if(preg_match(/^style/,$line2)) {
if(preg_match(/inkscape:label/,$lines2[$style_line_num])) {
$location = explode(=,$lines2[$style_line_num]);
$location2 = substr($patient_location[1],1,-6);
if(in_array($location2, $from)) {
$key= array_search($location2,$new_array); //Find out the position
of the index in the array
echo Key . $key . br; //This only gives me a blank space
after the word Key
}
} //end preg_match inkscape
} //If preg_match style
I looked at the example from
http://php.net/manual/en/function.array-search.php, and looks like what I am
trying to do here is possible, and yet, why am I not getting a proper key
return?
Thanks for your help.

[PHP] array search
Hello All,
I've been trying for days now to make this work.
I'm trying to search my array for a value and return the key.
I get the visitor's IP and try this -- this is the latest,
I've tried a few functions to echo the name associated with the viz_ip.
$viz_ip= $_SERVER['REMOTE_ADDR'];
$byte_ip= array(
204.126.202.56=Mark,
63.230.76.166=Bob,
63.220.76.165=John,
);
function _array_search ($viz_ip, $byte_ip) {
foreach($byte_ip as $key = $val) {
if ($viz_ip === $key) {
return($val);
}
}
return(False);
}
I'm no wiz but this shouldn't be this hard, maybe I'm thinking wrong.
I've read the examples at php.net but I just can't get it. Some help
or even a hint ?
best regards,
malcolm

and not in the elements myArray[0][1]
CODE:
for($l = 0; $l count($layer); $l++) {
$key = array_search($layer[$l], $layerDes); // $layerDes is 2-D
$layer[$l] = $layerNames[$key];
}
My $key is FALSE/0 after execution, is it because the elements are in
$layerDes[i][0]?
Using $key === also didn't help? Any ideas, thanks.

Oops! Sorry I got a reply for this but didn't read my mail carefully
enough. Thanks to Tim Ward for pointing out the problem.
I've a 2 D array and would like to search for vals. in the first dimension
only i.e.
myArray[0][0]
myArray[1][0]
myArray[2][0]
myArray[3][0]

[PHP] array search
I have an array of names, like below...
$people = array(Jim,John,JP);
Is there a way in an IF statement to see if someone's name is in the array?
Like...
if ($people =~ $person) { }
I don't want to have to create a foreach loop to go through the array to see
if that person is there.

Re: [PHP] array search
just to add some info. rememember this is case sensitive and spaces do
matter, sometimes (depending on your goals) the following will apply :
$good_names = array('jim','philip','sasheen');
$my_name= 'PHiliP';
if (in_array(trim(strtolower($my_name)),$good_names))
and, another good function is array_keys and array_search. see :
http://www.php.net/array

Philip Olson

RE: [PHP] array search
Joseph,
The below postings are what you're looking for. Hopefully the in_array PHP
function uses a smart search algorithm and doesn't go through the entire
array. If you store your values in a db you can make use of an index on the
column, or you could write your own search algorithm that uses a btree or
some other type of search methodology.

What about going the other way? Say I have a sentence...

RE: [PHP] array search
try this :
$people = array ('philip','sasheen','jim');
$string = 'Hi, my name is philip, I miss Sasheen';
foreach ($people as $person) {
if (stristr($string,$person)) {
$matches[] = $person;
}
}
// results live in $matches now.
print_r($matches);
stristr is case insensitive, strstr is case sensitive. modify to suit
your needs.

RE: [PHP] array search
btw, you may want to search for a name surrounded by spaces as philip vs
philips, jim vs jimmy, etc. probably other considerations as well, or
maybe not :)

Hi, my name is Bob. ...and I want to search the sentence for one of the values (people) in the array... $people = array(Jim,John,JP,Bob); Can this be done? Yes, split the sentence into parts of the array (use split or explode), then all you have to do is walk through $people with foreach askink if that word is in, for example $word that is the array that you got after the split (or explode).
