PHP - *new To Php* Need To Strip First Character From A String

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?

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

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

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!

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

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.

I have a paragrpah which has tags that needs to be stripped off.

so the paragraph looks like

Quote

<div id="ctl00_placeholderMain_pnlInTheBox" class="tabitem">                       <p>                      HP LaserJet 9050 printer<br/> Power cord<br/> Parallel cable<br/> HP LaserJet Q8543X Smart print cartridge<br/> Printer documentation<br/> Printer software CD<br/> Control panel overlay<br/> Face-up output bin<br/> Two 500-sheet input tray<br/> 100 Sheet Multipurpose Tray<br/> HP JetDirect Fast</p>                </div>


I want it to look like

Quote

HP LaserJet 9050 printer
Power cord
Parallel cable
HP LaserJet Q8543X Smart print cartridge
Printer documentation
Printer software CD
Control panel overlay
Face-up output bin
Two 500-sheet input tray
100 Sheet Multipurpose Tray
HP JetDirect Fast


How would I go on about doing this..

currently i use

Code: [Select]
$inbox = $html->find( "#ctl00_placeholderMain_pnlInTheBox" );

if ( isset( $inbox[ 0 ] ) )
{



$box =( $inbox[0] );

$box = strpos($box, ';') !== FALSE ? substr( $box, strpos( $box, ";" ) + 1 ) : $box; 


}
else
{
$box = "0";
}

I am building a component where users enter a Youtube URL and press save. I need to run some code on the form field where the URL was entered to strip all but the unique identifier. i.e. something like this:
$url = 'http://www.youtube.com/watch?v=_VaAlaIJ384&feature=rec-LGOUT-real_rev-rn-4r-10-HM';
strip all befor (including) 'v='
strip all after (including) '&'

Can anyone suggest how I would do this?

$name = "D'Angelo" 

ok I'm running a mysql query as

$query = " INSERT INTO TEST (ID, NAME) VALUES ('NULL','$NAME')";


If the name = "D'Angelo" the apostrophe would cause it to fail. Is there a way to do this without striping the characters? 

Hi everyone!
I'm trying to get the variables out of a string like this:
Code: [Select]
$string='this is a sentence with a load of [great, clever, textual] variables ';
What I want to do is output a list of strings that have used the variables to create unique strings like this:
Code: [Select]
this is a sentence with a load of great variables
this is a sentence with a load of clever variables
this is a sentence with a load of textual variables
I tried exploding the string into arrays, but what I really need to do is explode on '[' then output the words to an array (until I get to the closing ']') and then move on...

The eventual string will have potentially loads of variables, but let's do one thing at a time.

What's the best way of starting a project like this?

Hi All I Am confused

I would like to put info into a database but need it to be secure. I have some code shown below. The problem is I would like to put in ' but keep the data secure.
When it comes back I do not want to show \' I think you might know what I am trying to do.
Here is the code but would like to know how to stop the \' showing.
Code: [Select]
$password = mysql_real_escape_string(stripslashes(trim($_POST['password'])));
Any help would be great thank you.

Hi:

Is this the proper way to remove slashes from apostrophes:
Code: [Select]
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{

$myTitle = mysql_real_escape_string(stripslashes($_POST['myTitle']));
$myDesc = mysql_real_escape_string(stripslashes($_POST['myDesc']));
$myHeader = mysql_real_escape_string(stripslashes($_POST['myHeader']));
$mySubHeader = mysql_real_escape_string(stripslashes($_POST['mySubHeader']));
$myPageData = mysql_real_escape_string(stripslashes($_POST['myPageData']));


It seems to work fine, I'd just like to clarify I'm not missing anything.

Thanks!

This is going to sound like a very beginner question, because it is. I am modifying some free code snippets to fit my use and stuck. It's probably a simple fix.

First here is the code. This is printing from a while loop.
<?php print("[". $current_month .",". number_format($remaining_balance, "2", ".", ",") . "],");?>

Here is the last remaining items from the loop at it comes to an end:
[343,14,495.86], [344,13,682.26], [345,12,863.91], [346,12,040.79], [347,11,212.87], [348,10,380.12], [349,9,542.52], [350,8,700.02], [351,7,852.61], [352,7,000.26], [353,6,142.94], [354,5,280.62], [355,4,413.26], [356,3,540.85], [357,2,663.34], [358,1,780.72], [359,892.95], [360,0.00], 

My question is kind of simple, how do I get it do the comma doesn't print on the last print? I need it to end like this: [359,892.95], [360,0.00]

Does that make sense? I don't know if I explained it well. I could really use some help! Thanks so much!

Firstly I'm sure the answer is simple however due to my inexperience I am unable to figure it out!   I am executing a simple query to retrieve all ISBN numbers within my db and display these in a table. In my db some of the ISBN numbers contain hyphens and some don't. I would like to display then in my table without hyphens.   I'm grateful of any assistance and advice.   I know I can remove all the hyphens from the db by executing a separate query however I'd like to strip them if possibly.   My Code;

$query = "SELECT * FROM book WHERE status != 'Archive' ORDER BY id";

while($row = mysqli_fetch_array($query)){ 

?> 

<tr>
<td><a href="itemView.php<?php echo '?isbn='.$row['isbn']; ?>" </a></td>
<td>...</td>
<td>...</td>
<td>...</td>
<td>...</td>
</tr>   

<?php  }  ?>

Hey guys. I am trying to strip everything between a key phrase and ending tag but for some reason it is not working. I always get blank data. I've tried many different ways but no luck.   basically I have a script that connect to imap and store emails into MySQL as service tickets. works great but I am trying to strip everything except for user reply because currently if a user reply to an email it re-inserts the entire email into MySQL. I added a key phrase at the top of all outgoing emails .   1. structure looks like this.   --Reply below this line to respond-- ------------------------------------------------------------------------------------------------   Email body message...   2. When replying to the message it becomes   New Message reply......   --Reply below this line to respond--   old message body.     3. so I would only like to insert the new reply message only.     This is what I got so far.       $message=strip_tags($message, "<br><div><p><u><hr></section>");       $message=preg_replace("</p>", "br /", $message);
   
    $message=preg_replace('#--REPLY above this line to respond--(.*?)</section>)#s', ' ', $message);
   
    $message=clean("<br/><hr><u>Received On $rep_date / $from_email</u><br><br/>$message");     it inserts the "Received On date and From but $message is blank.   If i remove $message=preg_replace('#--REPLY above this line to respond--(.*?)</section>)#s', ' ', $message);  it inserts the entire email   Any suggestion on what i am doing wrong?   thank you all very much.
