PHP - Finding Word In A String This Way...

This topic has been moved quickly to PHP Regex because I need to go to work instead of lurking phpfreaks.

I have a DB of data: article-id, section-id, subsection-id, article-text. When a row is fetched I am displaying article, section, subsection as <h3>, <h4>, <h5> and then text in a <p>. Before outputting the text I want to scan it for other articles, sections, or subsections it may reference then turn that reference into a hyperlink. I read the PHP documentation but I can't find anything that translates to the basic commands of instring, indexof, and left/mid/right. 

Example:

1. Article Name

100. Article 1, section 1

100.a article 1, section 1, subsection a

Text blah blah blah 105.f blah blah blah

 

I want to find that 105.f and turn it into a link. All my articles, sections, and subsections are in the DB so I know I can use an array of the number values as my items to look for, but I can't figure out how to look.

%3$s displays a string of text that always begins with a number followed by a colon (from 1-25 only).

1:
2:
3:
etc...

Is there a way to remove the number and the colon entirely and leave the rest of the string intact?

Code: [Select]
function wp_rss( $url, $num_items = -1 ) {
if ( $rss = fetch_rss( $url ) ) {

if ( $num_items !== -1 ) {
$rss->items = array_slice( $rss->items, 0, $num_items );
}
//start count
$i = 1;
foreach ( (array) $rss->items as $item ) {
printf(
'<div title="%2$s"><strong>'.$i.'</strong></div><div>%3$s</div>',
esc_url( $item['link'] ),
esc_attr( strip_tags( $item['description'] ) ),
htmlentities( $item['title'] )
);
//increment
$i++;
}

I want to catch the first word of a string in which the words are separated by "-" (e.g. "first-word-second-one-more"). I used this code: $string = explode('-', $string);
echo $string[0];

The problem is that when the string contains only one word, it returns null 

Whats the quickest way to find a word in a string and wrap <b> tags around it?

Code: [Select]
$search =  "php web";
$striing = "PHP is the web scripting language of choice";

Basically im looking for the output to be :
"<b>PHP</b> is the <b>web</b> scripting language of choice"

There are many ways to delete everything after a character in a string. I am looking for a simple way to delete everything after a given word.

I have been becoming more and more familiar with PHP over the past few months, but this problem stumps me.

How can I take a string of words separated by spaces taken from an XML feed (example: word1 word2 word3 word4)

and turn it into something like this:

<a href="word1">word1</a>
<a href="word2">word2</a>
...

and so on. This has to be done on the fly, since it is taking the words from the XML feed, they change depending on the page.

I want them to be in a vertical column, and be able to link each one to the search page for that word, so each link has to be different.


An even more in-depth problem, how can I sort it then so that there are multiple columns if necessary, say one page only has 3 words, but another has 50. How can I split them up into multiple vertical columns, say with 10 words in each?


Have I confused anyone yet?

How could I split a string in half but not in the middle of a word?


$information = "This is the string of text, however at some point in the sentence a word may get split in half.";
$cut = round(strlen($information)/2); ///where to cut (50%)
$split1 = substr($information, 0, $cut); //first half
$split2 = substr($information, $cut); // second half

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 != $Server['server_port'])
{
// edit the value
}
else if($Entry->maxplayers > $Server['server_slots'])
{
// edit the value
}
}
}

Hi

I have a file, that is copied from other files. All other files work perfectly.
But, for some reason this one is throwing back an error.

Any help finding this bug will be a big help.

Thanks
