PHP - Regex Or Explode To Array: I Need Some Help In A Simple String!

Hi, I'm trying to explode an array into a multidimensional array using <br /> tags as splitters but just can't get the syntax right! I can do lines of the array one by one, but not the whole lot at once. I'd really appreciate a quick example of an explode inside an array.

$myarray looks something like this with print_r:
(
    [0] => 
    [1] => some_html<br />some_html<br />some_html<br />
    [2] => some_html<br />some_html<br />some_html<br />
    [3] => some_html<br />some_html<br />some_html<br />
)

and I want to turn it into this:
(
    [0] => 
    [1] =>
     [0]some_html
     [1]some_html
     [2]some_html
    [2] => 
     [0]some_html
     [1]some_html
     [2]some_html
    [3] =>
     [0]some_html
     [1]some_html
     [2]some_html
)

I've tried this
$myarray = explode ("<br />", $myarray);
but it doesn't work …

It doesn't matter too much if there's are a few empty lines in the array from the final <br /> tags.

Many thanks, as ever, for any help.

Hi,
Im trying to pull an email from an url, and then echo the email as value into a email form-- under the "from" heading. The echo is not working i get blanks.

here is the code:
<?php 
$thisurl='$_SERVER['REQUEST_URI']';  
    $thepart = explode('/', $thisurl);
$themail='$thepart[2]';
?>
<form method="post" action="sendit.php">
To: <br><input type="text" name="to" size="44" value="<?php  for($i=1; $i<=$lines; $i=$i+1)
{
    $names[$i] = str_replace("<br>", "", $names[$i]);
    $names[$i] = str_replace("\n", "", $names[$i]);
echo $names[$i].';';
}

?>"><br>
From: <br><input type="text" name="email" size="44" value="<?php echo '$themail'; ?>" readonly><br>
Subject: <br><input type="text" name="subject" size="44" /><br><br>

Hi all!

This is probably fairly simple for someone who is used to dealing with arrays. I have an array of data(Parsed from an XML document) containing a string I would like to further split into another array.

The string is along the lines of:
"<name>":<value>,"ID":20251,"ID2":2300,"ID3":2000

How can I split the above into:
Array[<NAME>] => <VALUE>

Notes:
<name> changes often. depending on the query, it may have different <name> values.

I have been trying to do it with preg_split and got to:
Array ( => "<NAME>":<VALUE> [1] => "ID":20251)

but I need to split it further at ":". I tried a foreach, but I failed miserably.

Can anyone point me in the direction of better practice for arrays/preg_split? I have looked into the PHP documentation, but it is not enough for me.

Thanks in advance

This php program reads it back to the screen as it is writen and as you see it above.
Code: [Select]
<?php

The code below fails. I feel it is because I am using 'explode' incorrectly.
Code: [Select]

Everything I've been able to find over the web, tells me this is what I need to do if I want to add some text that tells what each responce means.

I have strings that can look like this "monkeys / cats/ dogs / snakes".

I have code that breaks the items apart and puts each as a separate item into an array, like this (where $getstring['thestring'] equals strings like the example given above)...

Code: [Select]
$array = explode("/", strtolower(trim($getstring['thestring'])));
foreach($array as $k=>$v)
{
$array[$k] = trim($v);
}
}
My question is how can I add some code so that if there are ever instances where there is nothing between  each /, it does NOT put that "blank" into the array?

For example, if a string was something like "monkeys / cats/ / dogs/ eagles / / snakes", the code now would create two array items that are essentially "blank" because there were two consecutive slashes, two different times in that same string.

These strings are entered by users so there is definitely a possibility they make a mistake such as above so I need a way to weed out those mistakes (i.e. the blanks).

Any ideas for easiest way to find the "blanks" and NOT have them in the array?

Hi there,

Need a little help here if anyone has the time.

In short, I have a page that is dynamic, that sends POST data to a handler, pretty standard stuff. Normally, for me anyway, I know what the field names will be in advance and handle then as usual.

In this case the form content is created dynamically from a GUI I created and the names of the fields are suffixed with the product ID. Within the handler I have stripped the  POST data down to the main two vars, namely the pid- product ID and qty- quantity ordered and within a loop created a string to explode() like;

9_33_21_66


$oStrArray = explode('_', $ostring);

echo "ostring[0] =".$oStrArray[0];
echo "ostring[1] =".$oStrArray[1];
echo "ostring[2] =".$oStrArray[2];
echo "ostring[3] =".$oStrArray[3];


Result =>

ostring[0] =9
ostring[1] =33
ostring[2] =21
ostring[3] =66

Now, the 1st, 3rd, 5th etc will be the pid and the 2nd, 4th, 6th etc. will be the qty.

Only two sets are used in this example, normally 50+ pairs of values will be present.

If it helps with the loop that I need to create - if a foreach will not suffice - I can deduce how may pairs will be present and send this as a var via GET from the form setting a value for i, for instance.

I need to be able to, within a loop,

* pull the first value as a pid

* run a subroutine to pull the data from the DB table to get all the product info to display on a confirmation page [this is not ecom - just emailed orders for existing clients] I can do all the MySQL Query stuff it is just rationalising the data extracted from the array

Well I am sure you can see from that what I am trying to do, I will need to do the multiplications etc.

I do not know how to handle the data in the array created by the explode()

In logic I would say this

if x in $ostring is even then $ostring is a product id [mysql query to get details from table] next item in array is corresponding quantity - print details of product in a table, do the multiplication to give line total and add to $message ready for email - NEXT pair of vars

I really hope that makes sense and someone can point me in the right direction - thanks in advance for any assistance.

Ok, this was driving me nuts.  I think I found the cause, but need help fixing it.  I have a bunch of answers in a MySQL database in the form of...

Miami Heat/heat/miami
Orlando Magic / orlando/ magic
etc.
etc.

*Notice how sometimes there are leading or ending spaces (i.e there is a space before "magic" but NOT a space before "miami")...

I run this code to bring back the answers data (all acceptable answers) in an array.  I then look for the user entered answer ($userinput, which has trim and strtolower run on it) in the array.

Using this code below, the answer IS found if $userinput is any of the Miami Heat options, but it is NOT found if it's any of the Orlando Magic options.  The only difference is the fact that there are spaces in the Orlando Magic stuff.  Apparently, the trim() function is only removing space from the beggining and end of the ENTIRE string.  But I need to trim() each item in the array. How can I do this?  Seems like it should be easy but can't figure it out.

Code: [Select]
$sql = "SELECT * FROM answers
WHERE quizid = $quizid";
$result = mysql_query($sql, $connection);
if (!$result) {
die("Database query failed: " . mysql_error());
} else {
while ($getanswers = mysql_fetch_array($result)) {

$array = explode("/", strtolower(trim($getanswers['answer'])));

if (in_array($userinput,$array)) {
echo "the answerid = " . $getanswers['answerid'] . "<br>";
} else {
echo "the answerid is not found= <br>";
}


}

}

Hey,

Im trying make a way to check an input to make sure it only consists of "1,2,3,4,5,6,7,8,9,0 and . " I thought i could explode the number and check it to an array that has "1,2,3,4,5,6,7,8,9,0 and . "

I havent worked with arrays before so i dont quite know how they work or to go about this?

Any ideas cause im sure im not the first to ask for something like this

Thanks

Hi, I'm not sure if this is a wierd one, I have lots of arrays i'm looping through like this to see them:-


for($i=0; $i <count($confirmed); $i++){//loop through
     print_r_html($confirmed[$i]);
}


Which shows the following :-

Code: [Select]
Array
(
    [0] => AAAAAA-BBBBBB
    [1] => 2
    [2] => 2010-09-29
)
Array
(
    [0] => AAAAAA-BBBBBB
    [1] => 2
    [2] => 2010-09-28
)
Array
(
    [0] => CCCCCC-DDDDDD-EEEEEE
    [1] => 3
    [2] => 2010-09-29
)
Key 0 is a Groupconcat split by "-"
Key 1 shows how many fields are in 0
Key 2 is just the date

What I would like to do is split the first array into 2 arrays, the second in 2, and the third into 3 (therefore ungrouping the groupconcat if you will)
as such:-

Code: [Select]
First into these two:-
Array
(
    [0] => AAAAAA
    [1] => 2
    [2] => 2010-09-29
)
Array
(
    [0] => BBBBBB
    [1] => 2
    [2] => 2010-09-29
)
Second into these two:-
Array
(
    [0] => AAAAAA
    [1] => 2
    [2] => 2010-09-28
)
Array
(
    [0] => BBBBBB
    [1] => 2
    [2] => 2010-09-28
)
Third into these two:-
Array
(
    [0] => CCCCCC
    [1] => 3
    [2] => 2010-09-29
)
Array
(
    [0] => DDDDDD
    [1] => 3
    [2] => 2010-09-29
)
Array
(
    [0] => EEEEEE
    [1] => 3
    [2] => 2010-09-29
)
)
I know I can get out the info from the first of the keys in each array by putting this into the loop:-


for($i=0; $i <count($confirmed); $i++){//loop through
     if($i==0){
             $seperated[] = explode("-",$confirmed[$i]);//split by "-"
     } 
}
    print_r_html($seperated);



but i'm not sure how to copy the other keys at the same time? If anyone has got any ideas that would be great!
thanks in advance

I have a regex that validates a string. I want to ensure there is no space in the string. Thus far I have used the negative look ahead regex construct as shown below to match strings without spaces.

(?!.*(\s))

While this prevents space in between a word, all strings with space characters at the end or beginning are getting validated. I do not want that at all.   This is the full regex script below:

$string = "#JebiamgoOeing0";
if (preg_match('/^.*(?=.{8,})(?!.*([A-Za-z0-9])\1{1})(?=.*[a-z])(?=.*[A-Z])(?!.*(\s))(?=.*[\d])(?=.*[\W]).*$/', $string))
{
    "do something";
}
else
{
   "do something else";
}

I need help in resolving this.   Thank you.

Given the below rules and following browser input: user/joe/x

I am working on a csv file import to mysql, which will include items in one table (irrelevant here), and a hierarchical table of categories (id | name | parent).  I would think the simplest method to get each category name is too explode the categories from the csv into an array, for example:
$array = "root/Business/Employment";
$categories = explode("/", $array);

My problem though, is figuring out what the ID's are for each of the categories without knowing each name will be unique and not knowing for sure the full depth of each category hierarchy either.  So (I think) I need to rely on the category structure to define the lowest level ID.

So something like this:
Code: [Select]
SELECT
t1.parent AS p1,
t1.name AS lev1,
t1.id AS cat1,
t2.name AS lev2,
t2.id AS cat2
FROM
(categories AS t1)
LEFT JOIN categories AS t2 ON t2.parent = t1.id
WHERE t1.parent = '1'
AND t2.name = "Employment";

This gives me the ID of Employment, but it's easily possible that the name will be duplicated somewhere else in another heirarchy (in fact I get 4 results from phpmyadmin).  And since I don't know all these will be only 3 levels deep, it won't work all the time.

Any ideas help would be greatly appeciated!

Hi Guys. This should- hopefully- be a pretty simple question for someone with regex experience to answer. I've been reading all the regex guides and tried various things but none have worked and I'm starting to get a headache. I've decided to just pitch the question here.

How do I test if a string contains ONLY a certain character- but could be one or more instances of that character. In this case it's a comma. So:

','           -> Would return TRUE
',,,'         -> Would return TRUE
',,,,,,,'     -> Would return TRUE

',,,hello,' -> Would return FALSE
'hi,,,'       -> Would return FALSE


Thanks in advance!
