PHP - Break Down A String

Hi,

I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads.  Here is uploadify.php as it currently looks:

Code: [Select]
<?php
session_name("MyLogin");
session_start();

$targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root

if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name'];

// Validate the file type
$fileTypes = array('m4a','mp3','flac','ogg'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);

if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}

echo $targetFolder;

?>
I added Code: [Select]
echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'.  For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'.  The folder for username exists, with correct permissions, and when I manually enter Code: [Select]
$targetFolder = '/songs/nick';all works fine.  Which strikes me as rather strange.  I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string.

Any help would be much appreciated.  It's the last issue with a website that was due to go live 2 days ago!

Thanks,

Nick

Hello all,

I'm trying to change the end of a javascript call based on the end of the url string. The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible!

at the moment i've got

Code: [Select]
<?php

       $url = $_SERVER['REQUEST_URI'];

     $tag = strstr ($url, 'sobi2Id=');

       echo $tag; 
?>
but this returns an unexpected T_STRING, expecting ',' or ';'

Can anyone debug this? I may well be being really silly!

Hey there,

Thanks for taking the time to read my thread. My issue is that I can't think of a way to edit a XML file using PHP's XML functionality and then assign the edited contents to a string instead of saving the file. Because my issue is that I have to edit the XML file based upon a string brought from a remote location then give it back to that remote location using a string again, to be exact I am doing it via Linux command line utilizing SSH2.

This is what I managed to complete on my own.


function CheckIVMPConfig($ServerID)
{
global $Panel;

if(is_numeric($ServerID) && $this->IsValidServer($ServerID))
{
// We select the game server that the FTP account was created for.
$Servers = mysql_query("SELECT * FROM control_servers WHERE server_id = '".mysql_real_escape_string($FTPAccount['ftp_server'])."'");
$Server = mysql_fetch_array($Servers);

// Here we select the Box ID that the game server is on.
$Boxs = mysql_query("SELECT * FROM control_machines WHERE machine_id = '".$Server['server_machine']."'");
$Box = mysql_fetch_array($Boxs);

// Now we select the required package for the box.
$Packages = mysql_query("SELECT * FROM control_packages WHERE package_id = '".$Server['server_package']."'");
$Package = mysql_fetch_array($Packages);

// Retrive the file.
$Config = $CProtocol->exec("cat /home/{$Server['server_id']}/{$Package['package_config']}");

$Parse = SimpleXMLElement($Config);

foreach($Parse as $Entry) // loop through our books

if($Entry->port != $Server['server_port'])
{
// edit the value

hey guys im trying to find a string inside a string which could be made up of different things eg...

{$test}, {$test1}, {$test2}   
etc (but the varable inside could be called anything hence maybe using regex im not sure?)
is this possible?...i hope you guys understand....thanks

I have the following function, which takes a string with commas in it and attempts remove those commas. The way I have it here is that I use explode to take out the commas, which makes an array, and then iterate through that array to put a string back together without the commas.

function tags_to_sort_by( $sortMeta ) {      
   $sortByArray = explode(",", $sortMeta);
   $sortByCount = count($sortByArray);
   for ($i = 0; $i < $sortByCount; $i++) {
      $sortByString += $sortByArray[$i];
   }
   return $sortByString;
}

What does not work is the following line:
$sortByString += $sortByArray[$i];
Somehow that outputs a 0, which I don't understand. It should output something like: arrayItem1 arrayItem2 array3 etc.

My question is if there either is an easier way to remove the commas from the original string or what I am doing wrong in this line:
$sortByString += $sortByArray[$i];  // I am trying to concatenate each part of the array back into the string.

Thanks a lot for help with this!

How can i break down strings for example i have a simple search database for products where as a user searches a term this can be one, two three words and so on.

I'm using a wildcard; but i want the best way to get the possible search so i would like to break down the string into separate words and then use that to search the database using wildcards

is this possible?

Thanks for reading. 

Good morning,

I passed a bunch of HTML tags over a function that delete then, keeping just the text between. The problem is, after that all the tags were replaced by line breaks. Something like this before the function:

<tr>
<td>
Text
</tr>
</td>

After the function the 4 tags were correctly removed but instead i receive just the string "Text" I receive 2 line breaks, the "Text" and other 2 line breaks, like this:



Text



In HTML code this line breaks has no tags like <br> or <p> it's just blanck lines. I need to get just the text, how can I get rid of then? I tried this and also didn't work.

$text = str_replace("/n", "", $text );

Thanks

Hi all,

I realised as users register themselves in the registration form, they wrote their comments and experience in the comment box which was provided

Example (this is the content which they have written)
'Sentence 1 - Abccafsafsafafasdfafasfafs

Sentence 2 - dasddsadsadsadsdaddsda'


As you can see, between Sentence 1 and 2 there is a break (space).
However when we store it in our database, and generate it out as a webpage, the break (space) is gone, and sentence 1 and 2 merged

Example
'Abccafsafsafafasdfafasfafsdasddsadsadsadsdaddsda'

My question is, how can we prevent 2 different sentences from merging? Thanks

Below is my code and attached it what has been generated after we have posted it in webpage


Code: [Select]
cho '<div id="panel3">';
echo '<table>';
/***Tutor's Comments***/
echo'<div id="tutor_comments">';
echo '<br/><tr><td class="row_header">Tutor\'s Comments</td></tr>';
if (!empty($row2['tutor_comments'])) {
echo '<tr><td>' . $row2['tutor_comments'] . '<br/><br/></td></tr>';
}
/***Tutor's Commitments***/
echo '<tr><td class="row_header">Tutor\'s Commitment</td></tr>';
if (!empty($row2['tutor_commitment'])) {
echo '<tr><td>' . $row2['tutor_commitment'] . '<br/><br/></td></tr>';
}
/***Admin_comments***/
echo '<tr><td class="row_header">Admin\'s Comments</td></tr>';
if (!empty($row2['admin_comments'])) {
echo '<tr><td>' . $row2['admin_comments'] . '<br/><br/></td></tr>';
}

echo '</table>'; //End of Panel 3's table
echo '</div>'; //End of tutor_comments DIV

I want to have a line break between the lastname and the age. Please help.

echo $line["firstname"].' '.$line["lastname"].' Age is'.$line["age"].'!';

Code: [Select]
$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= $row['Field'].",";
$i++;
}
}
$csv_output .= "\n";

$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j].", ";
}
$csv_output .= "\n";
}

print $csv_output;
I'm using the above to get a csv output in my browser, but it appears as a string of text
eg
a1,a2,a3,a4,b1,b2,b3,b4,...

I'd like it to appear as
a1,a2,a3,a4
b1,b2,b3,b4
c1,c2,c3,c4

Any ideas how?

echo '<div class="gamename">'.$values[0].'</div>';
echo  '<div class="gameimage"><a href="'.$values[3].'"><img src="'.$values[1].'"></a></div>';

NOW i want 2nd echo under 1st echo. I tried every single <br> combination but no luck   

Also my 2nd question is: my image and link is a variable, it displays the image but there is something wrong with link.
Variable is just like this  www.mydomain.com\image\blabla.php
but it shows link as==> www.mydomain.com\     instead of what i wrote above.

I was wondering if you guys could help me 'break' a function I've been working on. It converts a CSV-formatted string to a 2d array following RFC4180. Here's the function.

/**
 * 
 * Covert a multi-line CSV string into a 2d array. Follows RFC 4180, allows
 * "cells with ""escaped delimiters""" and multi-line enclosed cells
 * It assumes the CSV file is properly formatted, and doesn't check for errors
 * in CSV format.
 * @param string $str The CSV string
 * @param string $d The delimiter between values
 * @param string $e The enclosing character
 * @param bool $crlf Set to true if your CSV file should return carriage return
 *  and line feed (CRLF should be returned according to RFC 4180
 * @return array 
 */
function csv_explode( $str, $d=',', $e='"', $crlf=TRUE ) {
// Convert CRLF to LF, easier to work with in regex
if( $crlf ) $str = str_replace("\r\n","\n",$str);
// Get rid of trailing linebreaks that RFC4180 allows
$str = trim($str);
// Do the dirty work
if ( preg_match_all(
'/(?:
'.$e.'((?:[^'.$e.']|'.$e.$e.')*+)'.$e.'(?:'.$d.'|\n|$)
# match enclose, then match either non-enclose or double-enclose
# zero to infinity times (possesive), then match another enclose,
# followed by a comma, linebreak, or string end
| ####### OR #######
([^'.$d.'\n]*+)(?:['.$d.'\n]|$)
# match anything thats not a comma or linebreak zero to infinity
# times (possesive), then match either a comma or a linebreak or
# string end
)/x', 
$str, $ms, PREG_SET_ORDER
) === FALSE ) return FALSE;
// Initialize vars, $r will hold our return data, $i will track which line we're on
$r = array(); $i = 0;
// Loop through results
foreach( $ms as $m ) {
// If the first group of matches is empty, the cell has no quotes
if( empty($m[1]) )
// Put the CRLF back in if needed
$r[$i][] = ($crlf == TRUE) ? str_replace("\n","\r\n",$m[2]) : $m[2];
else {
// The cell was quoted, so we want to convert any "" back to " and
// any LF back to CRLF, if needed
$r[$i][] = ($crlf == TRUE) ?
str_replace(
array("\n",$e.$e),
array("\r\n",$e),
$m[1]) :
str_replace($e.$e, $e, $m[1]);
}
// If the raw match doesn't have a delimiter, it must be the last in the
// row, so we increment our line count.
if( substr($m[0],-1) != $d )
$i++;
}
// An empty array will exist due to $ being a zero-length match, so remove it
array_pop( $r );
return $r;

}

And to use it:

$csv = 'this,will,"be ""separated""",by
"commas,",,"should work with
""multiline,"",
",entries
some,last,data,"test"';

print_r( csv_explode($csvn) );

or

$csv_eurwin = "this;will;'be ''separated''';by\r\n";
$csv_eurwin .= "'semicolons;';;'should work with\r\n";
$csv_eurwin .= "''multiline;'';';entries\r\n";
$csv_eurwin .= "some;'last';data;'test'";


print_r( csv_explode($csv_eurwin, ';', '\'', TRUE) );

Thanks! Here's the actual spec if anyone cares
Code: [Select]
   1.  Each record is located on a separate line, delimited by a line
       break (CRLF).  For example:

       aaa,bbb,ccc CRLF
       zzz,yyy,xxx CRLF

   2.  The last record in the file may or may not have an ending line
       break.  For example:

       aaa,bbb,ccc CRLF
       zzz,yyy,xxx

   3.  There maybe an optional header line appearing as the first line
       of the file with the same format as normal record lines.  This
       header will contain names corresponding to the fields in the file
       and should contain the same number of fields as the records in
       the rest of the file (the presence or absence of the header line
       should be indicated via the optional "header" parameter of this
       MIME type).  For example:

       field_name,field_name,field_name CRLF
       aaa,bbb,ccc CRLF
       zzz,yyy,xxx CRLF

   4.  Within the header and each record, there may be one or more
       fields, separated by commas.  Each line should contain the same
       number of fields throughout the file.  Spaces are considered part
       of a field and should not be ignored.  The last field in the
       record must not be followed by a comma.  For example:

       aaa,bbb,ccc

   5.  Each field may or may not be enclosed in double quotes (however
       some programs, such as Microsoft Excel, do not use double quotes
       at all).  If fields are not enclosed with double quotes, then
       double quotes may not appear inside the fields.  For example:

       "aaa","bbb","ccc" CRLF
       zzz,yyy,xxx

   6.  Fields containing line breaks (CRLF), double quotes, and commas
       should be enclosed in double-quotes.  For example:

       "aaa","b CRLF
       bb","ccc" CRLF
       zzz,yyy,xxx

   7.  If double-quotes are used to enclose fields, then a double-quote
       appearing inside a field must be escaped by preceding it with
       another double quote.  For example:

       "aaa","b""bb","ccc"
