[PHP] Explode Question
I need to explode an array with an array.
$one = array(0 ='golf', 1 = 'field');
$two = array(0 = On the golf course or in the field of clover);
$array_exp = explode($one, $two);
print_r('pre');
print_r($array_exp);
print_r('/pre');
Notice: Array to string conversion.
I have done this before but it is slipping my memory how I did it.
I do NOT want to foreach over the initial array and read the second array for
each position.
I am not even sure I used the explode function.

What's the desired result?
array('golf' = On the golf course or in the field of clover,

RE: [PHP] Explode Question
The desired result is.
Array
(
[0] = On the;
[1] = course or in the;
[2] = of colver;
);
I am just not sure the delimiter can be an array in the Explode function.

explode() takes three parameters; string, string, [int]. Where [int] is
optional.
Ex:
$ipList = '192.168.1.0,192.168.1.1,192.168.1.2';
$ipList = explode(',',$ipList);
Returns an array of strings:
Array
(
[0] = 192.168.1.0,
[1] = 192.168.1.1,
[2] = 192.168.1.2
);

Here's something to mess around with, to fit to your liking.
?php
$one = array('golf','field');
$two = array(On the golf course or in the field of clover);
$result = array_explode($one,$two);
print_r($result);
function array_explode($delimiters,$array)
{
if ( !is_array($delimiters) || !is_array($array) ) {
//bail
return;
}
$string = $array[0];
$regex = @(.implode('|',$delimiters).)@;
return preg_split($regex,$string);
}
?

[PHP] Explode-update-implode not working
At least not the way I expected it to. Apparently I am doing something
wrong, but I can't find anything specific that explains it. This is in
PHP 5.2.6.
Here is the sequence I am trying to implement without the database
portion. (This is typed in since the VNC I am using doesn't support
pasting from a Linux client to a MS-Windows server.)
-
$buff = key1|value1~key2|value2;
$lines = explode (~, $buff);
foreach ($lines as $kvpair) {
$line = explode (|, $kvpair);
if ($line[0] == key1) {
$line[1] = value3;
$kvpair = implode (|, $line);
break;
}
}
$newbuff = implode (~, $lines);
-
$kvpair is modified, but that change is ignored by implode() with
$newbuff still containing key1|value1.
So why doesn't the change to $kvpair get brought in by implode? What
should I do to update that value?

See the second note at

Either of these should do what you want:
?php
$buff = key1|value1~key2|value2;
$lines = explode (~, $buff);
foreach ($lines as $kvpair) {
$line = explode (|, $kvpair);

Doh! I knew it would be something simple that I had overlooked. I recall

that was then ...
Thank you, the code is working better now. I just wish I were.

Thank you for the reply... =)
I'll check this... BTW:
array explode ( string $delimiter, string $string [, int $limit] )
So, I was wrong...
The right way, probaly, is:
$str=explode(\n,$_POST[my_text]);
If it's coming from a textarea you'll want to use \r\n because a
textarea uses both a carriage return (\r) and newline (\n) to separate.
Otherwise each element of the array will have a \r on the end which
may end up causing you some issues later on.
I was wondering about this, I seem to recall that window/mac/*nix all do
it differently.
With a little Google'ing I came across this.
http://www.sitepoint.com/forums/printthread.php?t=54074
This was written in 2002, so I am not sure about the Mac = \r.
Since they are using *nix now, it could be \n not sure
But the article had this to say:
Line breaks
People want to know how they can retain textarea line breaks in HTML.
You should store text in the database in its original format (e.g. with
just newlines) and then use nl2br() to convert newlines to HTML br /
tags on display (thanks to the people here for teaching me that :)).
That's all good, except for one problem with nl2br(): it doesn't seem to
convert \r newlines (edit: this has now been fixed in PHP 4.2.0).
Windows uses \r\n newlines; *nix uses \n; Mac uses \r.
nl2br() works correctly on text from Windows/*nix because they contain
\n. However, if you get text from a Mac, nl2br() will not convert its
newlines (again, fixed in PHP 4.2.0). To remedy this, I use the
following bit of code to convert \r\n or \r to \n before inserting it
into the database. It won't hurt anything and ensures that nl2br() will
work on the \n only newlines on display. Also, it has the side effect of
saving 1 byte in the database per newline from Windows (by storing only
\n instead of \r\n). :)
PHP Code:
$txt = preg_replace('/\r\n|\r/', \n, $txt);
Fair enough :)
I guess my thinking was since a textarea is a html 'standard' it would
be consistent across all browsers/systems. I guess not :)

Another way to write that PCRE pattern is /\r\n?/ (one carriage
return followed by zero or one linefeed).
I recall also running into \n\r although I can't recall which system uses it.
As an alternative to PCRE, we can pass arrays to PHP's replace functions, e.g.:
$txt = str_replace(array(\r\n, \n\r, \r), \n, $txt);

I was wondering about this, I seem to recall that window/mac/*nix all do
it differently.
With a little Google'ing I came across this.
http://www.sitepoint.com/forums/printthread.php?t=54074
This was written in 2002, so I am not sure about the Mac = \r.
Since they are using *nix now, it could be \n not sure
But the article had this to say:
Line breaks
People want to know how they can retain textarea line breaks in HTML.
You should store text in the database in its original format (e.g. with
just newlines) and then use nl2br() to convert newlines to HTML br /
tags on display (thanks to the people here for teaching me that :)).
That's all good, except for one problem with nl2br(): it doesn't seem to
convert \r newlines (edit: this has now been fixed in PHP 4.2.0).
Windows uses \r\n newlines; *nix uses \n; Mac uses \r.
nl2br() works correctly on text from Windows/*nix because they contain
\n. However, if you get text from a Mac, nl2br() will not convert its
newlines (again, fixed in PHP 4.2.0). To remedy this, I use the
following bit of code to convert \r\n or \r to \n before inserting it
into the database. It won't hurt anything and ensures that nl2br() will
work on the \n only newlines on display. Also, it has the side effect of
saving 1 byte in the database per newline from Windows (by storing only
\n instead of \r\n). :)
PHP Code:
$txt = preg_replace('/\r\n|\r/', \n, $txt);
Hope this helps

I would think a more efficient strategy would be a simple string
search. If you append a comma to the beginning and the end of your
list so it becomes:
,12,7,10,6,14,11,2,
then you can search for:
,#,
where # is the desired integer.
Therefore you could use the MySQL syntax:
WHERE CONCAT(',', `groups`, ',') LIKE '%,7,%'
OR CONCAT(',', `groups`, ',') LIKE '%,14,%'

thanks for the idea.. i also just came up with a solution using mysql
FIND_IN_SET
eg: FIND_IN_SET('7', groups) OR FIND_IN_SET('14', groups)

If this is early in the application development, look into 3rd normal form for SQL tables (don't worry about 4th or 5th). In a nutshell, here is what you should be doing: you have a many to many relationship (big thing to note). Whatever holds groups (lets call it foo) to groups. So you should do something like this: === Foo --A table === Id -- columns groups Coln === Groups === Id Col1 Col2 Col3 So then you create a 3rd table named === Foo_has_groups (or groups_has_foo, whichever sounds best) === Fooid groupsid So then, you can do much more powerful queries, with much less overhead. Such as: SELECT t1.* FROM foo t1, groups t2 WHERE t1.id=t2.whatever_id AND (t2.group=7 OR t2.group=14); If you are reluctant to do any of these optimizations to your database, then you better not worry about anywhere in your PHP code to do _ANY_ optimizations. This will be your system bottleneck! 99% of the time (maybe less) when you get a slow application, your bottlenecks will be in your sql queries/design.

[PHP] explode a string
Sorry jocham, for you getting this twice.
I'd assume foreach is recommended because it lends to more readable
code. More readable code, is generally considered better code.
Personally I'd disagree and use while( list() = each() ), because it
doesn't create a copy of the array in memory, especially for the
array. If you're dealing with an array where the elements are large,
or multi-dimentional, you may want to consider a different approach,
such as assigning by reference, like:
for($keys = array_keys($sample_array); $key = each($keys), $val =
$sample_array[$key]; )
but that is very ugly untested code(and I'm drunk), so I wouldn't
recommend you copy n paste it.
besides for the sake of 200 bytes, with an average of around 5
characters per word, it pretty much doesn't matter, which you use.
Even something as crappy as ASP would easly deal with 200b.

[PHP] explode and PATH_SEPARATOR
Taking this code: pre ?php define (PATH_SEPARATOR, /); $String=Root/One/Two/Three/Last; $arr = explode ( PATH_SEPARATOR, $String ); var_dump ( $arr ); $arr = explode ( /, $String ); var_dump ( $arr ); ? /pre It works fine in second case returing a five elements array, but in the first one it returns an array with just one elemen that's the source string itself. I've test it also changing PATH_SEPARATOR by SEPARATOR in both cases, and it works nice... Is PATH_SEPARATOR any kind of reserved word or so?

PATH_SEPARATOR is is a predefined constant, so you'll need to use
something else, but you still need to put quotes around it:
define('NOT_PATH_SEPARATOR', '/');

[PHP] Explode, Arrays and Checkboxes
I'm not new to PHP, but I have very little experience with arrays. I have comma separated values in a database, that I need to pull out, explode into an array, then check certain checkboxes if they exist. I have two variables: $x = 2,10,34 $y = 28,15,16 I need to explode them both, so that the values of $x are they keys, and the values of $y are the values. Is that possible? I have a form, with checkboxes that are named $product[1] through [40]. Next to them are textboxes labeled $price[1] through [40]. How would make the form, when it loads, have $product[2], [10], [34] checked, with $price[2], [10], and [34] equal to 28, 15, and 16 respecively. Any help would be greatly appreciated. -- Matt Winslow [EMAIL PROTECTED]

What is the relationship between the $x,$y and $product,$price?
I'm not sure I quite grasp what your trying to do.
If I understand correctly, the situation you describe ends up not
being a one-one relationship. So a user could select 4 prices with
3 products or vice versa. Which will make things difficult to match
up products/prices.

[PHP] explode() an array and grep out a string
Hi all.
Is it possible to explode an array and have it exclude a certain
string. I currently have an array that is an ldapsearch that returns
sub-accounts of a parent account. These accounts are then displayed so
customer can either change the passwd or delete them.Thing is
ldapsearch returns everymatch which includes the parent account, which
is already listed on the page as the parent account. I would like to
eliminate the second listing of the parent account where the
sub-accounts are listed.
This is where the array is collected:
$search = ldap_search($connection,dc=isp,dc=com,
ispParentAcct=$sessUsername);
$entries = ldap_get_entries($connection, $search);
$num = $entries[count];
if ($num) {
$sessSubAccounts = ;
$i = 0;
while ($i $num) {
$sessSubAccounts .=
$entries[$i][uid][0] . |;
$i++;
}
}
One thing I would like to point out is that I did not have this problem
before, but when I updated to a new version of openldap the following
ldapsearch would no longer return the subaccounts:
$search = ldap_search($connection,dc=isp,dc=com,
homeDirectory=/home/$sessUsername/*);
Any idea why that may be?
This is where the array is exploded:
?
$i = 0;
if ($sessSubAccounts) {
$accounts = explode(|, $sessSubAccounts);
while ($i count($accounts) - 1)
?

Try this:

$ldap_results = array('account1','account2','parent_name');
$results = array_diff($ldap_results, array($parent_account));
$results will now have only account1 and account2.

[PHP] explode()
I am having a user enter a phrase into a textbox, and then I need to
seperate the words he has typed into variables so I can use each one
in an sql statement. I know I will use the explode() function to do this,
but how will I know how many variables I've created. For instance, if a
user types in 3 words seperated by spaces, how will I know i'll have
var[0] through var[2]? how about when they type in 2 words or 4 words?
How will I know how many words they have typed in? The only way I can
think of to do this is:
// $var is the input after being ran through explode()
$i = 0;
while ($var[$i])
{
$i++;
}
I will then take the data they enter and create the sql statement:
$j = 0;
$sql = select subject from subfile where;
while ($j = $i)
{
$j++;
$sql .= suject matches '*$var[$j]*';
if ( $j != $i)
{
$sql .= and ;
}
}
but I think there has to be a better way to do this. any ideas?

Do you first split the lines?
What about a simple strpos and substr?
$colon=strpos(':',$res) will get you the position of only the 1st colon.
then strpos ($res, 0, $colon-1) will get you the 1st part
and strpos ($res, $colon, strlen($res)) the second part.
disclaimers: not tested. not guaranteed to be working. just a suggestion.
check the manual to fix it.

[PHP] explode and escape character for string separator
Hi all, Suppose I have a long string like $myStr = $string1:$string2:$string3; I can obviously explode them using : as the separator. But what if $string1 contains the character : by itself? I was thinking, first I am gonna put an escaping character, so I can do something like: $string1 = str_replace(:, \:, $string1); But that still won't work with explode. So, what can I use instead of explode? Anything simple, and fast? This is a hypothetical situation. The real situation is that I am trying to have a protocol for data sent by client using Flash. But the basic question remains. Thanks for any help. RDB -- - /\ ASCII Ribbon Campaign against HTML \ / email and proprietary format X attachments. / \ - Have you been used by Microsoft today?

Re: [PHP] explode and escape character for string separator
One set of delimiters I often use for text files is ~~ or ^^. They are
fairly unique. If they do appear in a file then there is probably
garbage in the file and I want to know about. For my templates
delimiter I use {::TagName::}. You could use }::{ as your delimiter.
Don't limit yourself to just a single character. Although the upside
down ! or ? are nice if you are not using Spanish.

load a bunch of characters into an array. Do a loop through that array and check all of your $strings for the current character in your loop.

[PHP] explode, split, or what?
Thank you to those of you who helped me with my last problem earlier today.
Now I have a text file (setup.txt) that has a series of values all seperated by
\r\n's. Inside of another file I'm trying to read setup.txt into $rawSetupData and
explode that with \r\n's into an array called $setupData. My problem is that the
explode function doesn't seem to be doing anything, and neither is split which I tried
also. Here is my code:
setup.txt

$setupData = explode(\r\n, $rawSetupData);

}
else echo Error opening \setup.txt\;

file() returns the file in an array, each line as new value, so line nr.
