PHP - Explode On Special Character?

Hi people!
I have a form with a select list where options are populated from a table in my db..
the string format is like this -> car - branch (ex. toyota - japan so on..)
when viewing the options it displays correctly with the "-" but when i tried submitting the form which will be inserted into the db
the "- branch" gets cut off..
i think i need to encode it but i don't know how to do it..

thanks for any reply! 

I have this code to pull the first few words from the body text to use as a title. But, when the body contains apostrophe, it shows on my title as '. I found the following code that's supposedly fixes the code. But, I can't figure out how. I need to add this:
$return = = htmlspecialchars_decode(token_replace($output, 'node', $node), ENT_QUOTES);
Or something similar ... to this:
Code: [Select]
$limit = 10;
$text = $node->body[$node->language][0]['value'];

$text = strip_tags($text);
      $words = str_word_count($text, 2);
      $pos = array_keys($words);
      if (count($words) > $limit) {
          $text = substr( $text, 0, $pos[$limit]);
          $text = trim( $text );
          $text = rtrim( $text, '.' );
          $text = trim( $text ) . '...';
      }

return  $text;

Thanks in advance.

Hi guys, I did read allot of documentation on the internet about reading/writing/parsing an XML file. I ended up using the following code, because I really have large files (some about 200MB) and regular dom does not work:

while ($xml->read()) {
switch ($xml->nodeType) {
case (XMLReader::ELEMENT):
if ($xml->localName == "job") {
$node = $xml->expand();
$dom = new DomDocument();
$n = $dom->importNode($node,true);
$dom->appendChild($n);
$job = simplexml_import_dom($n);


The problem I have is a special character error in the xml file, error returned on this line: "$node = $xml->expand();"

I am literally banging my head to the wall to find a simple solution to this. I already have a cleaning function, but that can be applied only after the code above. As the file is large, to clean it, I would have to use the same code above to work on partial content at once, so I would have the same special character problem when I would try to read and split the file.

I bet I am not the first one to be in this situation, but after about 5 hours of searching on the internet, I cannot do it no more. And I am not a php expert to come up with a new idea.

One other thing to do probably would be to split the file into multiple files, and read them after that, without using the XMLReader. But this would ask for a different application.

If, for example, on a file where I have an error, I do the reading with simplexml, without using the XMLReader, I don't get the error. But I cannot use simplexml on the files, since file size is variable. I have to use a reliable method that works for all situations.

Hopefully someone has an idea to this STUPID situation!

Thanks.

If I explode a string well using a substring when I implode that substring is now missing.

for example.
Code: [Select]
$exploded = explode("[MAC]",$data);

$data = implode($exploded);
Now [MAC] would be missing in the $data string. any way to get around this?

Hi all,

I posted a similar question before and got some of the way but still need a little help.

I have a product database with a description column where there are strings broken into lines. I need to find a way to explode() by line break. Currently explode("/n") doesn't work - it only returns one array item. Can anyone help me out?

Thanks!

Hi, I have an array for prices :

forfait="158|Group Session,95|Group half session,45|Private Course,90|zumba course" which is used in a dropdown list where it shows as Group Session (158$) Group half session (95$) etc...

The prices need to be used as an 'amount' field on the gift certificate as the descriptions must show as a 'label' on the gift certificate.

So, I need to ' explode ' both the prices and the descriptions separately.

I can 'explode' de prices using $tmp_forfait=explode("|", $value) and I get 158 95 45 and 90

But, how do I get the descriptions separately, without the prices meaning I need to 'explode' the digits and '|' ...
Anyone can help me with that cope please?
Thank you

i want to explode a text field on the fly ?
for example
city,region.country
and to turn it
to
city_id,region_id,country_id

1.textfield from autocomplete
2.get post variable
3.explode
4 get ids
i played around with some ajax  with php
Code: [Select]
<html>
<body>
<input name="searchField" id="searchField" type="text" value="<?php echo $_POST['searchField'];?>"/>
<script type="text/javascript">
function Ajax(){
var xmlHttp;
try{
xmlHttp=new XMLHttpRequest();// Firefox, Opera 8.0+, Safari
}catch (e){
try{
xmlHttp=new ActiveXObject("Msxml2.XMLHTTP"); // Internet Explorer
}catch (e){
    try{
xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
}catch (e){
alert("No AJAX!?");
return false;
}
}
}
xmlHttp.onreadystatechange=function(){
document.getElementById('ReloadThis').innerHTML=xmlHttp.responseText;
var t=setTimeout('Ajax()',1000);
clearTimeout(t);
}

var searchfieldvalue=encodeURIComponent(document.getElementById("searchField").value)
xmlHttp.open("GET","getid.php?searchField="+searchFieldvalue+"",true);
xmlHttp.send(null);
}
window.onload=function(){
var t= setTimeout('Ajax()',1000);


}

</script>

<?php


/*explode searchField and generate ids
$searchField=$_POST['searchField'];
$p = explode(" , ", $searchField, 3);
$cityname=mysql_real_escape_string($p['0']);
$regionname=mysql_real_escape_string($p['1']);
$countryname=mysql_real_escape_string($p['2']);
*/
?>


<div id="ReloadThis">Default text</div>
</body>
</html>

//getid
<?php  
 $p=array();
 $p = explode(" , ", $_GET['searchField'], 3);
 echo $cityname=$p['0'];
echo $regionname=$p['1'];
 echo $countryname=$p['2'];

echo'<input type="hidden" name="place" id="place" value="'.$cityname.'"/>
<input type="hidden" name="region" id="region" value="'.$regionname.'"/>
<input type="hidden" name="country" id="country" value="'.$countryname.'"/>';

here ill add function to get city_id() etc

?>

Ok so what I have is a list of 32,000 IDs in a separate file called 32kIDs.txt and it has a list of roughly 32,000 user IDs for facebook which look like 100000233850312;1521225383;100000282767638;1252335882;1804268242

They're all separated by a semi-colon. What I need this script to do is echo each and every ID on screen, echoing each ID on a new line. I have been using the explode function but having trouble with it since I'm very new to PHP and don't have much experience yet.

Here is my current code:

<?PHP
$iFile = "32kIDs.txt";
$login = file($iFile, FILE_SKIP_EMPTY_LINES);
if(!is_file($iFile)) echo "The 32k add list couldn't be found...".sleep(999999);
foreach($login as $line_num => $line)
{
$login = explode(" ", htmlspecialchars(str_replace(";"," ",$line)));
 echo $login[0]."\n";
}
sleep(20);
?>

So I bet there are going to be things in there that I don't even need and thing's I'm missing, if anyone can help it would be much appreciated. And I'd like to keep the code short, I could just put in:
echo $login[0]."\n";
echo $login[1]."\n";
echo $login[2]."\n";
echo $login[3]."\n";

all the way up to echo $login[32246]."\n"; but yeah I don't like the thought of a 32k+ line script.

Anyways...

I'm trying to add options to products.

Currently, I have them in this format: Leather reinforced hilt,5.00::Stabbing tip,3.00::Logo,10.00

Code: [Select]
$option_results = mysql_query("SELECT product_options FROM products WHERE product_id='".$product."'");
   while($option_row = mysql_fetch_array($option_results)){
         $option = explode("::", $option_row[0]);
         $option_part = explode(",", $option[0]);
         $option_part[0] = $option_name;
         $option_part[1] = $option_price;
         echo "<li><a href=\"#\">".$option_name.", Add $".$option_price."</a></li>";
    }

I would like the output to be:

<li><a href="#">Leather reinforced hilt, Add $5.00</a></li>
<li><a href="#">Stabbing tip, Add $3.00</a></li>
<li><a href="#">Logo, Add $10.00</a></li>

I tried to do this:

explode(" ",$cp['size'])[0]


and it isn't working obviously. The reason I want it in one line is its in the middle of a big string and I'd like to keep all the code in one area. Is their a right way to do that other than setting it to a variable first?

hi,

now i have something like this:

$pizza  = "piece1 piece2 piece3 piece4";
$one_word = explode(" ", $pizza);

but i want to get 2 words together, like that:

$two_words[0]='piece1 piece2';
$two_words[1]='piece3 piece4';
$two_words[2]='piece2 piece3';
$two_words[3]='piece1 piece4';

if it's impossible with explode, then it's fine if you use some other function, i don't care as long as it works.

thank you, tastro

I store date data in MySql in this format DD-MM-YYYY , and now I need to explode this format when get information from database to get this:
$day = DD , $month = MM , $year = YYYY.

$result =  $db->query("SELECT 
user_birthday  
FROM users 
WHERE user_id = " . mysql_real_escape_string($_SESSION['user_id']) . " 
LIMIT 1");
$row = mysql_fetch_assoc($result);

$birthday = $row['user_birthday'];
and I get this date format: 12-07-1980

How to explode this 3 values in day, month, year?

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
