PHP - Remove " From String

Is there a way/function to not only remove <script>, <embed> tags etc but also remove the content within the tags so this:

"
some text
<script>
functionhere();
</script>
some more text
"

to this:
"
some text
some more text
"

In effect remove the whole tag and content within the tags? Havent been able to find anything online that works

Many thanks in advance.

Hi,

Im looking at using a statement like this to remove all text characters from a string.

  $outgoing = substr_replace($incoming,"",-1); 

The string is a currency that has a currency symbol in the beginning of the string, like "R500.00"

I would like to remove the R, so it is just a numeric value...

Please can you help me with any ideas on how to get this going? Been reading so much and its all confused me too badly.

Regards,
Chris

Hi is there anyway to check a string for any instances of something like this
"(3)" where the number "3" could be any integer. So basically I want to search a string for any instances of a integer in brackets "(integer)" and remove it.


So my string was something like


$string = "String (2) string string string (7)"

function($string)


output would be "String string string string"

where there integers in brackets could be any number

I know this one is probably super easy for you programmer types.. but I just need to know.. 

If a string ends with a dash (and not all of them will), how do I remove it? 

Thanks!

Hi, i have a query string id=5&start=0 that i want to remove from the url and return the url without it. I am searching a cleaner way for doing it. Here is an example :

Before : http://www.example.com/?a=3&id=5&start=0
After : http://www.example.com/?a=3

Before : http://www.example.com/?id=5&start=0
After : http://www.example.com/

Before : http://www.example.com/?alpha=1&id=5&start=0&beta=2
After : http://www.example.com/?alpha=1&beta=2

Thank you

Hi, I am new to the forums. I am having an issue with a snippet of code that generates random strings.  I have already searched the forums, but the fix that I found is already in my code.
I am still receiving the error though and was wondering if there was something else going on that I didn't see.  Here is my code:

Code: [Select]
        $Data = 'Ahmet'.md5(mt_rand(0, 123456789));

$length = 30;
$chars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
$string = '';
$string2 = '';
for ($a = 0; $a < $length; $a++)
{
$pos = mt_rand(0, strlen($chars)-1);
$string .= $chars{$pos};

$pos2 = mt_rand(0, (strlen($Data))-1);
$string2 .= $chars{$pos2};
}
I appreciate any help on this, as it is cluttering my system log table.
Thanks.

I've been struggling with being able to send an e-mail via the php mail() function when the body of the e-mail includes a "unique" URL.

The string that will not work is:

"https://p11.secure.hostingprod.com/@www.domain.com/dir/directory/file.ext"


The point within the string that breaks the capability, is the "/" after www.domain.com.  I have tried escaping it like so:

"https://p11.secure.hostingprod.com/@www.domain.com\/dir/directory/file.ext"

This allows the e-mail to successfully send,  however the body of the e-mail contains the backslash as well as the frontslash.

Any ideas?

I have sen this function before but can not remember what it is or how to code it. It allows you remove only defined characters from the end of the string. I am not looking to replace any occurrence anywhere in the phrase, just the end.

For example lets say I want to remove"ld!" from phrase "Hello World!" That function would return "Hello Wor"

Thanks

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.

Hello Everyone,

I am having issues where people are submitting null characters on my website (I.e. %00).  Currently, I check if their is a value by using the empty function, and I also am checking if the value after running the trim command is =="".  How can I check for these special characters to make sure that whatever they are submitting actually contains some sort of legitimate value?

Thanks!

Hi there - can anyone lend me a little advise as to what I'm doing wrong here.

I have this line:
$query=mysql_query("SELECT * FROM gallery a JOIN gallery_image b ON a.id = b.gallery_id where gallery_id=$gallery_id");

I am trying to add an order by statement: order by gallery_image.priority

So I created:
$query=mysql_query("SELECT * FROM gallery a JOIN gallery_image b ON a.id = b.gallery_id where gallery_id=$gallery_id order by gallery_image.priority");

But, I receive the error (even though there is table called "Gallery Image" and a column called "Priority":
Code: [Select]
Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/***/public_html/***/gallery.php on line 5
select: Unknown column 'gallery_image.priority' in 'order clause'

In a function of a php script there is the following code line:

function convert_mails($source_path, $mail_file = '') {
   global $output_path;
   print "sp=$source_path";
   // -- parameters must have a trailing backslash --
   if ($source_path[strlen($source_path)] != '\\') $source_path .= '\\';
  ...


When running it yields the following error:

sp=D:\storage\AABB.ACT\Archi0.FLD;
Notice: Uninitialized string offset: 35 in D:\WAMP\www\test.php on line 67

where line 67 is the line with the "if" statement.

So why and where is there an uninitialized string offset?
How can I repair the code?

Can someone please help me with an array problem i can not figure out.

I need the array to be numbered from 1 to how ever many fields that are needed in the form and have a mysql field name and the title of the field also in the array.

1, "mysql_field_name", "Title of form field"
2, "", ""

and so on

then the form will be shown based on the array.

I have the following draft code which I am working with.

any suggestions on how i may do this array ?

Code: [Select]
<?php
$options = array(
'1'=> array('fieldtext'=>'option1', 'mysqlfield'=>'option1'),
'2'=> array('fieldtext'=>'option2', 'mysqlfield'=>'option2'),
'3'=> array('fieldtext'=>'option3', 'mysqlfield'=>'option3'),
'4'=> array('fieldtext'=>'option4', 'mysqlfield'=>'option4'),
);


// $options = array(1 => "option1", "option2", "option3", "option4");

// the line above works but i want to include the name of the mysql field as well.

$userid = 1;

?>
<div style="align: center; margin: 12px; font-family:Tahoma;">
<br><br><?php
if ($_POST['Update'] != "Update") { // check if form submitted yet, if not get data from mysql.
$res = db_query("SELECT * FROM `users` WHERE `userid` = '" . $userid . "'");
foreach($options as $key => $value) { $_POST[$key] = mysql_result($res, 0, $value); }
$ok_to_update = "no";
} elseif ($_POST['Update'] == "Update") { // check if form submitted yet, if so get POST data.
// error checking
// foreach($options as $key => $value) {
// $_POST[$i] = "";
// }
$ok_to_update = "yes";
}

if ($_POST['Update'] == "Update" && $ok_to_update == "yes") {
// $res = db_query("INSERT INTO `users` () VALUES ()"); // add user details to database.
?><p><br><br><br>Thank you for updating</p><?php
} else {
?><form name="form1" method="post" action="">
<?php foreach($options as $key => $value) {
?><p><?php echo($value); ?>:&nbsp;<input type="text" name="<?php echo($key); ?>" value="<?php echo($_POST[$key]);?>"></p>
<?php } ?>
<input name="Update" type="submit" value="Update">
</form>
<?php } ?>
</div>

What am i missing here why echo 0 == "some string" prints out 1?
