PHP - Finding Character In A String?

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.

I have a $string with this structure "word-word2 something-SECONDPART". I want to divide it to $string1 and $string2 by separating with the last "-".

The point is that "-" exists in the first part, and I just want to make the second string after the last "-"

Hey all,

I'm looking to produce a random 10 character string like: abcABC0123 when the below method is called:

<?php

function randomize(){
   $chars = explode(' ',(range("a","z"))) . explode(' ',(range("A","Z"))) . explode(' ',(range("0","9")));
   $pass = "";
   for($i = 0; $i < $len; $i += 1){
      array_push($pass,$chars[rand(count($chars)-1)]);
   }
   return $pass;
}

var_dump(randomize(10));

?>
But the randomize method is not returning desired result. Any idea what I'm doing wrong?

Thanks for response.

I have this command that basically populates my website with titles for pages based on the information that is placed within "info.txt" I have multiple titles being created so I'd like a way of putting them in order beside alphabetically.

My thought was that I could place numbers as the first character in the "info.txt" file and that would allow me to put the titles in an order I find acceptable. Now this causes the issue that I don't want those numbers displayed on my website. So the Echo needs to strip the number.... I'm lost, but my brain thinks it's a good idea.

Here's the code I'm working with:

Code: [Select]
<tr>
<td id="body">
<table id="columns" cellspacing="0">
<tr>
<td>

<h2>LSAV Latest Events</h2>
<p>Select an event from below to view a gallery of images from that event.</p>
<ul>
<?php
$dir = 'latest-events';
if ($handle = opendir($dir)) {

    while (false !== ($file = readdir($handle))) {
if( $file != '.' && $file != '..') {
$title = file_get_contents( "$dir/$file/info.txt" );
echo "<li><a href=\"event-viewer.php?event=$file\">$title</a></li>";
}
    }
    closedir($handle);

How to remove the last character of a string if it is "-" ?

In replacing some elements in strings, sometimes "-" remains at the end. How to trim the string by removing "-", if it is at the end of the string?

i have to tables... forums & subscription

i would like to insert a random character string into 'forums' to be used as a subscription id.
and then have the same random string to be inserted into 'subscription'

How do you find out how many character within a String ??

for example:

$temp = "apple";

I want to return "5" for $temp as it has 5 characters. Thanks!

How can I check this string to see if it has a ~ character using php?

Code: [Select]
$string = 'userlocation~credentials~specialties';

I was wondering if anyone knows a good way to check for an even number of each character in a string.  For example if the string is "abbacc" then it will return true as there are two of each character.  However if the string is "ababc" it will return false as there is only 1 c.  Thanks for any help

Hi, and thanks for any help with this. 

I have this but of php i have been trying relentlessly to get working.. for over a month.
 

<?php
$abs="one two three four words";
$mT = "testing for matching words";

$words=explode(' ', $abs);
//$sf=($words);


if (preg_match($words, $mT))
{
        echo "the url $mT contains a Word";
}
else
{
        echo "the url $mT does Not contain a Word";

echo "$words[4]";

}
?>

You see, I get a responce only using the last line "$words[4]", (obviously, because I am pointing it the Matching word, (ie: with [4])
What i need to have is that the script will automatically "find" that Matching Word for me with ANYwhere of the string of $abs (not just the beginning or the ending)". 

not making it confusing, but the obvious word in this I am looking to find is the word, "words".
😕

Thanks so much for any help.

better description.

I have a form with some dropdownlist that get populated dynamically(depends on what the user chooses) with jquery and an xml file. In the form I have a button that takes the info and populates another form with the values of the ddl. I have coded script which populates the second form with jquery and the name of each input get dynamically added like so:

Code: [Select]
<input type="text" value="'+model+'" name="Model_'+model+'" id="'+model+'" readonly size="'+model.length+'" />
<input type="text" value="'+model+'" name="Model'+model+'" id="'+model+'" readonly size="'+model.length+'" />>
<input type="text" value="'+color+'" name="Color'+color+'" id="'+color+'" readonly size="'+color.length+'" />
<input type="text" value="'+part+'" name="Part'+part+'" id="'+part+'" readonly size="'+part.length+'" />
<input type="text" value="$'+price+'" name="Price'+price+'" id="'+price+'" readonly size="'+price.length+'" />
<input type="text" value="'+qty+'" name="Quantity'+qty+'" id="'+qty+'" readonly size="'+qty.length+'" />
<input type="text" value="'+total+'" name="Total'+total+'" id="'+total+'" readonly size="'+total.length+'" />

What I want to do is grab the name of the element and remove the underscore and everything else form rileft to right so I am left with just the word before the underscore. I tried using substr($key,0,-28) but that wont work since everything after the underscore will have a different length. I was wondering if there is a way i can keep everything before the underscore and remove the underscore and everything after that.
Thanks in advance for any input I get.

I have a kind of search and react on my site. The user can search for a number in a column as below

$search = mysqli_real_escape_string($link, $_POST["query"]);

$query = "SELECT * FROM $table[$i] WHERE oemnr LIKE '".$search."%' ORDER BY model";

 

The code works fine but I want to expand the function to get match for other numbers also. The oemnr column today can be 12345 which shows up if the user type 12.... 

I want to expand the oemnr column as

12345/03124/34713, numbers separated with / or another character.

If the user type 03... or 34... I want to find and show 12345 because it is on the same row and corresponds to the numbers on the same row. Is it possible to do in mysql? In php that kind of operation can be done with the explode function but I don't know how to use with mysql.

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

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
}
}
}
}
