How do I convert a string that has a - or + sign to a html friendly string?
I mean to convert those characters to html notations, like space is and so on...
ps: htmlentities doesn't work. I still see the -/+
Try this
$string = str_replace('+', '+', $string); // Convert + sign
$string = str_replace('-', '-', $string); // Convert - sign
I don't think there is entities for these symbols see: http://www.w3schools.com/tags/ref_entities.asp
I tested with
$str = "- and +"; echo htmlentities($str);
and didn't get entities. According to: http://us.php.net/manual/en/function.htmlentities.php
I would expect them to be encoded if there was encoding available.
No idea what you want to accomplish. But this escapes selected characters to html entities:
$html = preg_replace("/([+-])/e", '"&#".ord("$1").";"', $html);
As far as I am aware, - and + are fine in HTML, and dont have an entity equivalent. See http://en.wikipedia.org/wiki/List_of_XML_and_HTML_character_entity_references
Are you sure you're not thinking of URL encoding?
Specify that you want it to use unicode as follows:
htmlentities($str, ENT_QUOTES | ENT_IGNORE, "UTF-8");
Have a look at the 2nd comment on this page:
http://www.php.net/manual/en/function.htmlentities.php#100388
This will enable more encoding characters.
If you just want to encode some, then this is a little lighter weight:
<?php
$ent = array(
'+'=>'+',
'-'=>'+'
);
echo strtr('+ and -', $ent);
?>

I plan to use my custom function below while getting from data from my mysql table & print it as html. Since htmlspecialchars() translate tags to html entities, I retranslate them ( p, br, strong) to tags. My question is: Is it efficient enough or Is there any other shorter or more efficient way to achieve this aim? If you know any, can you please guide me with at least keywords? I can look fort he details in php.net and this site. Thanks, regards
function safe_output_from_mysql($safe_echo_to_html)
{
$safe_echo_to_html = mb_convert_encoding($safe_echo_to_html, 'UTF-8', mb_detect_encoding($safe_echo_to_html));
$safe_safe_echo_to_html = htmlspecialchars($safe_echo_to_html, ENT_QUOTES, "UTF-8");
$safe_echo_to_html = preg_replace("<br />","<br />",$safe_echo_to_html);
$safe_echo_to_html = preg_replace("<p>","<p>",$safe_echo_to_html);
$safe_echo_to_html = preg_replace("</p>","</p>",$safe_echo_to_html);
$safe_echo_to_html = preg_replace("<strong>","<strong>",$safe_echo_to_html);
$safe_echo_to_html = preg_replace("</strong>","</strong>",$safe_echo_to_html);
return $safe_echo_to_html;
}
There is no need to call preg_replace() multiple times. You can use a single pattern to match all the desired tags:
preg_replace('/<\s*(\/?(?:strong|p|br)\s*\/?)>/i', '<\1>', $s);
I'm assuming, of course, that you're actually planning to use regex to do the match. If the search strings are straight text, then strtr() is more efficient.
htmlspecialchars_decode: http://www.php.net/manual/en/function.htmlspecialchars-decode.php
This function is the opposite of htmlspecialchars(). It converts special HTML entities back to characters.
$str = "<p>this -> "</p>\n";
echo htmlspecialchars_decode($str);
The above example will output:
<p>this -> "</p>
Please see the function htmlspecialchars_decode($str); function.
I have:
$str = 'test%2B';
echo html_entity_decode($str);
I want it to return test +
What am I doing wrong?
NOTE: Sorry, the string cannot be modified. It's from an external source, I just need to make it replace the %2B with + signs somehow with PHP.
You didn't escape the space, and you should be using urldecode instead of html_entity_decode.
Try
$str = 'test%20%2B';
echo urldecode($str); // test +
If you wish to use html_entity_decode, use +:
$str = 'test +';
echo html_entity_decode($str); // test +
EDIT: If you need to decode a url that you cannot change yourself, urldecode should still work fine.
That string is encoded for a URL, not with HTML entities.
You need urldecode.
echo urldecode($str); // "test +"
An HTML-encoded string would look like this: test +, because none of those characters need HTML-encoding.
Try + instead. In your example, you are using URL encoding syntax and not HTML entity syntax.
In html a + is +. Try
$str = 'test +';
$str = "test %2B";
echo urldecode($str);
I need convert arabic letters in htmlentities symbols. Codepage: ISO-8859-1.
سك - this is arabic symbol for example.
htmlentities("سك")
returns:
س�
How can I get from this symbol the html-entities سك?
htmlentities() can do only characters that have named entities. See this question on how to convert arbitrary characters into numeric entities.
You're probably not targeting the correct charset. Try: htmlentities('سك', ENT_QUOTES, 'UTF-8');
i'm using a function to make sure there are no html code or cotation posted by user
function cleartext($x1){
$x1 = str_replace('"','',$x1);
$x1 = str_replace("'",'',$x1);
$x1 = htmlentities($x1, ENT_QUOTES, 'UTF-8');
return $x1;
}
so thank for ( ENT_QUOTES, 'UTF-8' ) it helped me to find what am looking for
Test string:
$s = "convert this: ";
$s .= "–, —, †, ‡, •, ≤, ≥, μ, ₪, ©, ® y ™, ⅓, ⅔, ⅛, ⅜, ⅝, ⅞, ™, Ω, ℮, ∑, ⌂, ♀, ♂ ";
$s .= "but, not convert ordinary characters to entities";
$encoded = mb_convert_encoding($s, 'HTML-ENTITIES', 'UTF-8');
asssuming your input string is UTF-8, this should encode most everything into numeric entities.
Well htmlentities doesn't work correctly. Fortunately someone has posted code on the php website that seems to do the translation of multibyte characters properly
I did work on decoding ascii into html coded text (&#xxxx). https://github.com/hellonearthis/ascii2web
I use the following lines of code:
$revTerm = "". strrev($limitAry["term"]);
$revTerm = utf8_encode($revTerm);
The $revTerm contains Norwegian characters as ø æ å. However, it is shown correctly. I need to reverse them before displaying, so I use the first line.
When I display them this way, I get an error of bad xml format - used to fill a grid.
When I try to use the second line, I don't get an error but the characters are not shown correctly. Could there be any other way to solve that?
If it may help, I use jqGrid to fill those data in.
strrev, like most PHP string functions, is not safe for multi-byte encodings.
try this example
$test = 'А роза упала на лапу Азора ウィキ';
$test = iconv('utf-8', 'utf-16le', $test);
$test = strrev($test);
// キィウ арозА упал ан алапу азор А
echo iconv('utf-16be', 'utf-8', $test);

Try this:
$revTerm = utf8_decode($limitAry["term"]);
$revTerm = strrev($revTerm);
$revTerm = utf8_encode($revTerm);
For using strrev you have to decode your string to a non-multibyte string.
