I have a string 90001 90002. I need to see which html special char is represented in the empty space. (It could be an empty space -   or it could be a textual line-break masquerading as a space in HTML see here. Maybe other possibilities that I'm not aware of..)

I would like to echo a string and show the empty spaces as html char (e.g. $result = "90001 90002").

I've tried using html_entities but that doesn't cover spaces. Also neither does htmlspecialchars. How would I go about doing this?
If possible I would like a purely PHP & html solution. If necessary - CSS. And if impossible otherwise, javascript will have to do..

Just an out-of-box thinking. I had the same issue but looked into using JavaScript's encodeURIComponent() function:

$(function () {
  $("div").html(function () {
    return encodeURIComponent($(this).html());
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>90001 90002</div>

Used jQuery as I am kinda lazy. You can do the same in JavaScript this way:

<div>90001 90002</div>
<script>
  var div = document.querySelector("div");
  div.innerHTML = encodeURIComponent(div.innerHTML);
</script>

Just letting you know that this is better to handle in client side than in the server side.

Update 2: Getting the HTML content and updating the text of the HTML:

$(function () {
  $("div").text(function () {
    return $(this).html().replace(/[\u00A0-\u9999<>\&]/gim, function(i) {
      return '&#'+i.charCodeAt(0)+';';
    });
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>90001—90002</div>

Something like this...

  • thanks! but i think you misunderstood the question. I'm not sure what the string will be. I am receiving it as an empty space and I need to print it to show what is there. (Your solution simply replaces the empty string with a character and then printing that chosen character..) – Ben Dec 26 '17 at 09:03
  • @Ben there is only java script that can you us for this – TarangP Dec 26 '17 at 09:06

function removeWhiteSpace($text)
{
  $text = preg_replace('/[\t\n\r\0\x0B]/', '', $text);
  $text = preg_replace('/([\s])\1+/', ' ', $text);
  $text = trim($text);
  return $text;
}

Editing the Answer :

if you need to do it using PHP , Use urlencode function , which would hep to resolve it 

<?php
$query_string = 'foo=' . urlencode($foo) . '&bar=' . urlencode($bar);
echo '<a href="mycgi?' . htmlentities($query_string) . '">';
?>

But they have set backs which is mentioned in the notes section of the documentation. http://php.net/manual/en/function.urlencode.php

You can also use functions like htmlentities,rawurlencode in php .

if you want to use it in javascript , You can use escape function. https://www.w3schools.com/jsref/jsref_escape.asp
