Re: [PHP] array question
Jim Lucas has it. You can use the preg_match function to find it. I would
use regexp for that reason. regexp is good for making sure things are typed
the way they need to (mostly used for).
Ravi.

Hello all!
I have a question regarding arrays and the way I can use a value.

do:
$a = explode(',', $s);
echo $s[2];
That's all fine, but is there a way to get the value directly, without
having to write another line in my script. I mean something like this:
echo explode(',', $s)[2];
or
echo {explode(',', $s)}[2];
I couldn't find out this answer anywhere, that's why I posted here.

Sure it CAN be done. Nobody laugh too loud here... But...
?php
$s = 'banana,apple,mellon,grape,nut,orange';
echo preg_replace('/([^,]+,){3}([^,]+).*/', '$2', $s);
?
Outputs: grape
The {3} part is equivalent to the array position. Change that number, and
you change which word will get displayed.

Because the array is not formed until after the explode you cannot do it
with one command, but you could place 2 commands on one line :)
$a = explode(',', $s); echo $a[2];

I guess a function is the way to go. I just have to see if the situation
comes up enough times to justify the function approach.

Re: [PHP] Array question
I'd also like to add to that:
$array = array();
$array[] = 'text';
$array[2] = 123;
$array[] = 'hello';
Would output:
$array(
0 = 'text',
2 = 123,
3 = 'hello',
);
Note the missing index 1, as php makes a numerical index that is one greater
than the highest already in use. As the index 2 was explicitly created, php
made the next one at 3.

Ash

Mike,
$results[] will automatically push a value unto the end of an array.
So doing this...
--
$magic = array();
$magic[] = 'a';
$magic[] = 'b';
$magic[] = 'c';
-
is exactly this same as doing this...
--
$normal = array();
$normal[0] = 'a';
$normal[1] = 'b';
$normal[2] = 'c';

And yes, in your example $results[] would be equivalent to $results[$j]

What PHP magic is at work here? Mike: That's just a shorthand way to populate an array in PHP. One of the reasons for this feature is that somewhere in your code you may not know what the next index should be. So, if you use -- $results[] = $next_item; -- then the $next_item will be automagically added to the next available index in the array. So you may be right in calling it PHP magic because I have not seen this in other languages. Understand?

When in Rome do as the Romans. PHP has a very distinct definition for an
array and for a string. If you think you're using C then maybe you
should go read the documentation. Assumptions based on previous
experience only go as far as they are right. Since you explicitly cast
to an array and not to a string, it can only be expected that you have
an array -- or an exception as you previously offered. But we know you
get an array because it's documented.
:)

There's not a built in function, but it's not hard to write one:

if (!is_array($needle)) { $needle = array($needle); }
$needle = array_map('preg_quote', $needle);

You can reduce the above statement to the following:
$needle = (array)$needle;
Conversion to array creates an array with one element... the value
converted.

Fair enough. I very rarely type cast in PHP, so it never occurred to

It will work if they are all unique. If you have any duplicates they

Hi All
I am having a bit of trouble with PHP arrays and would
appreciate some help.
I currently have the following piece of code
$count=count($data-legs-leg);
$k=0;
while($k $count)
{
$legrow[$k]=$data-legs-leg[$k]['legId'].$VM.$data-legs-leg
[$k]['depApt'].$VM.$data-legs-leg[$k]['depTime'].$VM.$data-
legs-leg[$k]['dstApt'].$VM.$data-legs-leg[$k]['arrTime'].$V
M.$data-legs-leg[$k]['equip'].$VM.$data-legs-leg[$k]['fNo'
].$VM.$data-legs-leg[$k]['cr'].$VM.$data-legs-leg[$k]['mil
es'].$VM.$data-legs-leg[$k]['elapsed'].$VM.$data-legs-leg[
$k]['meals'].$VM.$data-legs-leg[$k]['smoker'].$VM.$data-leg
s-leg[$k]['stops'].$VM.$data-legs-leg[$k]['eticket'];
$k++;
}
This works fine extracting the leg attributes from the legs array and
putting the data into a new legrow array delimited by $VM.
I can do a print_r($legrow); and I get the rows displayed
correctly. I can
also access any row by using $legrow[n] where n is the key number.
What I want to do is to find a way of indexing the array
using the legId
as the key if possible. In other words I want to extract the
row where the
legId has a particular value where I do not know the row key.
I have been thinking that this might be possible with an
associative array
but my attempts to do this have not worked.
What I have tried is as follows
$count=count($data-legs-leg);
$k=0;
while($k $count)
{
$legrow[$data-legs-leg[$k]['legId']]=$data-legs-leg[$k][
'depApt'].$VM.$data-legs-leg[$k]['depTime'].$VM.$data-legs-
leg[$k]['dstApt'].$VM.$data-legs-leg[$k]['arrTime'].$VM.$da
ta-legs-leg[$k]['equip'].$VM.$data-legs-leg[$k]['fNo'].$VM

meals'].$VM.$data-legs-leg[$k]['smoker'].$VM.$data-legs-le
g[$k]['stops'].$VM.$data-legs-leg[$k]['eticket'];
$k++;
}

Thanks for the answer.
That is what I had in my example that did not work.

I have tried $legrow[number];

s-leg[$k]['stops'].$VM.$data-legs-leg[$k]['eticket'];
$k++;
}
This works fine extracting the leg attributes from the legs array and
putting the data into a new legrow array delimited by $VM.
I can do a print_r($legrow); and I get the rows displayed
correctly. I can
also access any row by using $legrow[n] where n is the key number.
What I want to do is to find a way of indexing the array
using the legId
as the key if possible. In other words I want to extract the
row where the
legId has a particular value where I do not know the row key.
I have been thinking that this might be possible with an
associative array
but my attempts to do this have not worked.
What I have tried is as follows
$count=count($data-legs-leg);
$k=0;
while($k $count)
{
$legrow[$data-legs-leg[$k]['legId']]=$data-legs-leg[$k][
'depApt'].$VM.$data-legs-leg[$k]['depTime'].$VM.$data-legs-
leg[$k]['dstApt'].$VM.$data-legs-leg[$k]['arrTime'].$VM.$da
ta-legs-leg[$k]['equip'].$VM.$data-legs-leg[$k]['fNo'].$VM

$VM.$data-legs-leg[$k]['elapsed'].$VM.$data-legs-leg[$k]['
meals'].$VM.$data-legs-leg[$k]['smoker'].$VM.$data-legs-le
g[$k]['stops'].$VM.$data-legs-leg[$k]['eticket'];
$k++;
}
My thinking is that the $data-legs-leg[$k]['legId'] is the
legId and I
might use that as a key. This however does not work.
I would appreciate some guidance on how I might get this to work.

Please show a little more code, as it looks to me as though this should work

Specifically: how do we know what is in $c? how do you know the array_search
works? how do you know $n is only getting 'a', 'b', or 'c'? (Hint: var_dump()

Mike,
See entire function under topic Array question - maybe UTF?...
I am trying to change accented characters to their equivalent without accents.
And yes, the arrays look fine after var_dump()...

Nevermind. I read that wrong. $this-orders is an array of objects, like you said, which I glanced over too quickly. My statement above still holds, though. $this-orders[$OrderID=$value] still appears to be a typo to me. It might supposed to be: $OrderObject = $this-orders[$OrderID] which will return the order object at $OrderID location in the array ($OrderID being the array key). Then, $OrderObject-OrderID should work properly. However, I would think that echo $OrderObject-OrderID; should produce the same results as echo $OrderID; But I could be wrong since I'm not exactly sure how the order object looks. Perhaps doing a var_dump on the $this-orders would help us out? -- Ben Ramsey Zend Certified Engineer http://benramsey.com --- Atlanta PHP - http://www.atlphp.org/ The Southeast's premier PHP community. --- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Array question
http://www.php.net/manual/en/language.types.array.php
If you mean having an array inside an array, of course ? $arr =
array(array('data')); ?. There you have an array inside another
one, 'data' will be here $var['0']['0'].
If you meant using an array item as the key in another array,
then you do it as with a normal var ? $arr1[$arr2['0']]; ?.
Remember not to quote $arr2 just as you wouldn't a quote a var
when using it as the key.
In your question you're mixing both:
Example: $paArgs['aCheckBoxes[$iIndex]['sName']']
Unquote 'aCheckBoxes[$iIndex]['sName']' and put the $ sign in
front:
$paArgs[$aCheckBoxes[$iIndex]['sName']]
I hope this helped.

or

I usually prefer the empty array method vs. using unset for coding
things like:

foreach($arr as $key = val) {

If I used the unset function I'd have to check to see if the

If the answer is yes to both: $query=SELECT title, text, date FROM tableA as A, tableB as B WHERE A.date=B.date ORDER BY date Now (AFAIK) if table A has 2 entries on april1 and table B has 3 entries on april1, you would get 2x3=6 resulting rows with all possible combinations.

If you added a dummy field in the table that is minus one field, you might use the merge table, but I honestly have no idea whether this would be more or less efficient than sorting arrays in memory.

Possibly using array_keys()?
$keys = array_keys($doo);
echo First key is \{$keys[0]}\;
array_keys() comes in handy if you want to have random access to an
associtive array without knowing the keys.

Re: [PHP] array question
Hi Guys, This might be a bit of a newbie question, but I'm not sure how to search for this particular information as its hard to put in search terms. Say I have a mysql/file with information about variables. Eg, I have a string from a mysql database of 'test' Am I able to then, in PHP, assign whatever that string is to a variable name? Eg, the string 'test' is used to create the variable '$test'... What is in that variable, doesn't matter, just the fact that the script knows the name of the variable (which can change depending on what the strings are) I'm sure its an easy piece of code, like a string function, but I'm buggered if I can find it!

If the former you can use array_slice(), the latter key().

I want to find the name of the n-th value in an array. Not the value of
the n-th, but whatever name was given to it. Array_slice seems to just

Re: [PHP] Array question - Please help
Write your results to a file and create a mail from the file once a day and
send it to yourself with cron, or use a database to hold the results if one
is available.
Instead of making a mail message with your loop, write information back to
the file. Format your file like this:
url, pass, fail, last_fail_time
?
$url_file = url.txt;
$url_list = file($url_file);
//loop through each line
foreach($url_list as $line)
{
$part = expode(,,$line);
$url = $part[0];
if(isset($part[1])) { $pass = $part[1]; } else { $pass = 0; }
if(isset($part[2])) { $fail = $part[2]; } else { $fail = 0; }
if(isset($part[3])) { $last_fail = $part[3]; } else { $last_fail =
None; }
$fp = fsockopen ($url_list[$x], 80, $errno, $errstr, 30);
if($fp) { $pass++; } else { $fail++; $last_fail = date(r); }
$status[] = $url, $pass, $fail, $last_fail;
}
$new_file = implode(\n,$status);
$fp = fopen($file,w);
fputs($fp,$new_file);
fclose($fp);
?
The create another PHP script that simply loads up the .txt file and formats
an email with it to give you the results, and call it with cron/at.
I wrote that kind of quickly, so adapt to your needs and it may have
errors...but hopefully you get the idea. You can take out the isset() parts
if you want to go through and format your file in the correct format (with
all four columns). if you leave them in there, it'll basically take the file
you have now and reformat it to the new one the first time it's ran. Also
it'll make it so you can just add in a url, w/o having to put zero, zero,
and None for the other columns. adapt to your needs.

$arr2 is a 2d array.
$arr1[0] = 1;
$arr1[1] = 10;
$arr2[0] = $arr1;
print $arr2[0][1];
Result will be 10
But,
$arr1[0] = 1;
$arr1[1] = 10;
$arr2[0] = $arr1;
$arr3 = each($arr2);
print $arr3[1];
What are you expecting? Check out the documentation for each() at
http://www.php.net/manual/en/function.each.php
At this point $arr3 should look like this (I think, but try
print_r($arr3) to be sure):
{
0 = 0,
1 = array (
0 = array (
0 = 1,
1 = 10
)
),
key = 0,
value = array (
0 = array (
0 = 1,
1 = 10
)
)
}
Result is not 10. So, function each is not taking the whole $arr2[0]
out..
My question is what function should I use to iterate array elements
(with
arrays in it)?
How about foreach()?

Re: [PHP] Array Question
I can make this just a little easier.. try this
$query = SELECT * FROM mytable WHERE t_state_id_state in (' .join(', ',
$state). ');
if $state happens to be the name of the array that is passed from the
multi-select

Subject: [PHP] Array Question
I have some multiple select boxes in a form
ie
SELECT name=state[] multiple size=5 style=width:360;
option value=allall Regions /option
option value=16Region19 /option
option value=14Region14/option
option value=5Region15/option
these then get passed and I want to use them in mysql query
blah blah
WHERE
(t_state_id_state = $state[0])
Whats the best way of finding out how many items are in my array ?
And how can I step through the ones the exist ?
And can I only use LIKE % when my value is all ?
thanks

RE: [PHP] array question
Try using mysql_fetch_array instead of mysql_fetch_object.
You then then use a simple loop to assign your variables
e.g.
foreach($row as $k=$v)
{
$GLOBALS[$k] = $v; // or $GLOBALS[$k][$i++] = $v if multiple records
being read
}
This will result in a set of global variables matching your database fields
names.

Hi All,
I am trying to pull info out of a table and assign a var name to each
field... I seem to be having trouble. I have tried to do $var = $row[0]
but that does not seem to do it. I have included what is working below. I
would like to have each element of the array stored in a seperate variable
for use on a web page. Thanks
JG
?php
$stmt = 'SELECT * FROM custdata WHERE UserName like fred';
mysql_connect($localhost,test,testme);
$result = mysql_db_query(test,$stmt) ;
while($row = mysql_fetch_object($result)) {
//** doing this now**//
printf(%s,
$row-UserName) ;
// **Would like to do something like**//
// $user = $row[0]; //
}
mysql_free_result($result);
?

Why is that? Thanks for your help, Matthias From the docs: Similar to fgets() except that fgetcsv() parses the line it reads for fields in CSV format and returns an array containing the fields read. The field delimiter is a comma, unless you specify another delimiter with the optional third parameter. So it seems that $data will be an array of the current line being returned from the file? Have a look at the docs (/manual/en/function.fgetcsv.php) for an example of how to read and output the contents of a csv file. -- David Robley Techno-JoaT, Web Maintainer, Mail List Admin, etc CENTRE FOR INJURY STUDIES Flinders University, SOUTH AUSTRALIA hAS ANYONE SEEN MY cAPSLOCK KEY? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] Array question
Ok, But can't the array still be refered to with a number? So in myarray["something"] is the 50th element in the array, wouldn't: myarray[49] = myarray["something"] ?
