I have a feed that pulls from social feeds. These feeds can sometimes include special characters such as emojis that don't translate well:
I just want to strip out any characters that can't be displayed. I know that might remove a few that I could want but that's fine. I know I can do a regex but not really sure how to target like what's in the photo.
---EDIT---
This is what is throwing the characters above:
Try using PHP Sanitize Filters, most specifically FILTER_SANITIZE_SPECIAL_CHARS
<?php
$a = 'text including "unprintable" characters';
$sanitized_a = filter_var($a, FILTER_SANITIZE_SPECIAL_CHARS);
echo $sanitized_a;
?>
Just be careful using this if there are some characters you want (like < and > for instance)! Check the link at the top for a full list of filters you can choose from.

I want to get all the visible text from a url. I need to clear all html code and get plain text.
The process does not have to be perfect, but I would like the text to be as clean as possible.
Do you know any way to make it relatively simple?
Thanks!
Javi.
Have a look at strip_tags function.
strip_tags — Strip HTML and PHP tags from a string
It may do the job.
You can get url the value of the query string using $_GET['the names in there']. and use strip_tags to get only the text.
function get_url(){ return $_GET['name userd'];}
and use something like this

I want to translate text in my website like google translate (Not with it). I just need a sample php code that translate some of defined words (not the whole language).
here is my example code:
$text = "hello john";
$translated_text = str_replace("hello", 'Hallo', $text);
echo $translated_text;
does it execute fast on the server?
do i have to translate word by word?
You need to fill a dictionary in order to lookup for the words you want to translate.
Take a look at this answer, the code is meant to filter bad words, but should work in your case.

How do I place each word in a paragraph in its individual span tag? Currently I am using explode() and using a space to do this, but the I get the following:
"<span>Hello,</span> <span>I</span> <span>am</span> <span>Alec.</span>"
I will be using a dictionary lookup for each word, but "Hello," will not find what I'm looking for. Furthermore, I am stylizing the span depending on the word selected (through an onClick), so I don't want the comma to be part of the span.
Eventually, I want the following code to populate:
"<span>Hello</span>, <span>I</span> <span>am</span> <span>Alec</span>."
Theoretically it would be nice to do this without using explode() since I have to add all of these characters back into the text, but outside of the <span>. Is there a function to accomplish this?
Thank you!
Edit: I will be using this for everyday writing in different languages, so hyphenated words or letters outside of "A-Za-z" are expected.
preg_replace() can do that:
$str = 'Hello, I am Alec.';
echo preg_replace('/(\w+)/', '<span>${1}</span>', $str);
Output:
<span>Hello</span>, <span>I</span> <span>am</span> <span>Alec</span>.

UPDATED QUESTION
If I want to remove one or more characters in a textarea using php, how would I do this?
MY SOLUTION FOR A SINGLE INSTANCE
str_replace("http://","",$_POST['Website']);
How would I remove/replace multiple items or lower upper instances, i.e. HTTP//: http//: HTTPS:// https//: hTTps//: ?
You either should have fixed dictionary for allowed tags and good PCRE knowledge (remember to use lazy quantifiers) or (and this I would advise) use markdown syntax (there are js editors) and compile it in php to valid html.

I need to allow certain html tags (br,p and strong) and I have encountered this code.
(strip_tags($this->parent->content[$i]['text']), $this->parent->config, 'portal_mode_grid_news_text_length', '…').'</p>';
All I need is to allow those tags I have stated previously, but I don't know how to do it.
If you look at the documentation for strip_tags, it shows that the second parameter is "allowed tags", so an example of how to allow br, p and strong is like so:
$string = "Hello<br>";
echo strip_tags($string, "<br><br/><p><strong>");
Adding br and br/ together allows both types of line break as opposed to just one.
(strip_tags($this->parent->content[$i]['text'], "<br><br/><p><strong>"), $this->parent->config, 'portal_mode_grid_news_text_length', '…').'</p>';
