I'm having some troubles splitting a string by paragraphs.
I have a string inside $item->description, but it doesn't seems to be doing what I need.
My code:
$text = explode("</p>", $item->description);
var_dump($text);
It's outputing only the positions with all text, not doing the split:
array(1) { [0]=> string(726) "<b>Requirements</b> <p>A zeal towards learning to learn
as a priority. A sound knowledge of Internet and Browsing!</p> <b>Description</b> <p>The
course DIGITAL SKILLS FOR TEACHERS inherits the requirements for being a ROCKSTAR
Teachers with competency towards excellence within classrooms on narration with experience
and making a wow feature a continuous activity in classrooms on priority. The course
modules the expertise to imbibe for all teachers towards excellence with the adoption
of technology in a big very way!</p> <b>Who is the target audience?</b> <p>Any individual
who feels teaching is Sharing. A must for all Educators.</p>" }
Anyone could help me? Thanks!
Check this one :-
$text = $item->description ;
$arr = explode("</p>", $text);
echo "<br>".$arr[0] ;
Hope it will not come out with any issue .
If you want to get the plain text then you can use the strip_tags function. It will remove all the html tags from your text including paragraph tags.
For example:
/** Replace the <b> tag with placeholder */
$text = str_replace("<b>", "$", $item->description);
/** Replace the <\b> tag with placeholder */
$text = str_replace("<\b>", "^", $item->description);
/** Remove html from the text */
$text = strip_tags($text);
/** Replace placeholder with <b> tag */
$text = str_replace("$", "<b>", $item->description);
/** Replace placeholder with <\b> tag */
$text = str_replace("^", "<\b>", $item->description);
Alternately you can use the preg_match_all function. It will extract all text between paragraph tags. For example:
/** The text between paragraph tags is extracted using regular expression */
preg_match_all("/<p>(.*)<\/p>/iU", $item->description, $matches);
/** Each element of $text array contains text within a paragraph */
$text = $matches[1];
Use this format:-
$text = explode(PHP_EOL, $item->description);
Hope this will work .
You can use this code too :-
$text = preg_split('/\r\n|\r|\n/', $item->description) ;
echo $text[0] ;

I have this text : http://pastebin.com/2Zgbs7hi
And i want to be able to remove the HTML code from it and just display the plain text but i want to keep at least one line break where there are currently a few line breaks
i have tried:
$ticket["summary"] = 'pastebin example';
$TicketSummaryDisplay = nl2br($ticket["summary"]);
$TicketSummaryDisplay = stripslashes($TicketSummaryDisplay);
$TicketSummaryDisplay = trim(strip_tags($TicketSummaryDisplay));
$TicketSummaryDisplay = preg_replace('/\n\s+$/m', '', $TicketSummaryDisplay);
echo $TicketSummaryDisplay;
that is displaying as plain text, but it shows it all as one big block of text with no line breaks at all
Maybe this will earn you some time.
<?php
libxml_use_internal_errors(true); //crazy o tags
$html = file_get_contents('http://pastebin.com/raw.php?i=2Zgbs7hi');
$dom = new DOMDocument;
$dom->loadHTML($html);
$result='';
foreach ($dom->getElementsByTagName('p') as $node) {
if (strstr($node->nodeValue, 'Legal Disclaimer:')){
break;
}
$result .= $node->nodeValue;
}
echo $result;
This example should successfully store text from html into an array of strings.
After stripping all the tags, you can use preg_split with \R special character ( matches any newline sequence ) to convert string into array. That array will now have several blank values, and there will be also some amount of html non-breaking space entities, so we will check the array for empty values with array_filter() function ( it will remove all items that do not satisfy the filter conditions, in our case, an empty value ). Here are a problem with entity, because and space characters are not the same, they have different ASCII code, so trim() function will not remove spaces. Here are two possible solutions, the first uncommented part will only replace   and check for white space characters, while the second commented one will decode all html entities and also check for spaces.
PHP:
$text = file_get_contents( 'http://pastebin.com/raw.php?i=2Zgbs7hi' );
$text = strip_tags( $text );
$array = array_filter(
preg_split( '/\R/', $text ),
function( &$item ) {
$item = str_replace( ' ', ' ', $item );
return trim( $item );
// $item = html_entity_decode( $item );
// return trim( str_replace( "\xC2\xA0", ' ', $item ) );
}
);
foreach( $array as $value ) {
echo $value . '<br />';
}
Array output:
Array

Now you should have clear array with only items with value in it. By the way, newlines in HTML are expressed through <br />, not through \n, your example as response in a web browser still has them, but they are only visible in page source code. I hope I did not missed the point of the question.
try this get text output with line brakes
<?php
$ticket["summary"] = file_get_contents('http://pastebin.com/raw.php?i=2Zgbs7hi');
$TicketSummaryDisplay = nl2br($ticket["summary"]);
echo strip_tags($TicketSummaryDisplay,'<br>');
?>
You are asking on how to add line-breaks to your "one big block of text with no line breaks at all".
Short answer
After you stripped the HTML tags, apply wordwrap with a desired text-block length
$text = wordwrap($text, 90, "<br />\n");
I really wonder, why nobody suggested that function before.
there is also chunk_split around, which doesn't take words into account and just splits after a certain number of chars. breaking words - but that's not what you want, i guess.
PHP
<?php
$text = file_get_contents('http://pastebin.com/raw.php?i=2Zgbs7hi');
/**
* Returns string without html tags, also
* removes takes control chars, spaces and " " into account.
*/
function dropHtmlTags($string) {
// remove html tags
//$string = preg_replace ('/<[^>]*>/', ' ', $string);
$string = strip_tags($string);
// control characters and " "
$string = str_replace("\r", '', $string); // remove
$string = str_replace("\n", ' ', $string); // replace with space
$string = str_replace("\t", ' ', $string); // replace with space
$string = str_replace(" ", ' ', $string);
// remove multiple spaces
$string = preg_replace('/ {2,}/', ' ', $string);
$string = trim($string);
return $string;
}
$text = dropHtmlTags($text);
// The Answer: insert line breaks after 95 chars,
// to get rid of the "one big block of text with no line breaks at all"
$text = wordwrap($text, 95, "<br />\n");
// if you want to insert line-breaks before the legal disclaimer,
// uncomment the next line
//$text = str_replace("Regards Legal Disclaimer", "<br /><br />Regards Legal Disclaimer", $text);
echo $text;
?>
Result
first section shows your text block
second section shows the text with wordwrap applied (code from above)
Hello it can be done as follows:
$abc= file_get_contents('http://pastebin.com/raw.php?i=2Zgbs7hi');
$abc = strip_tags("\n", $abc);
echo $abc;
Please, let me know whether it works
you may use
<?php
$a= file_get_contents('a.txt');
echo nl2br(htmlspecialchars($a));
?>
<?php
$handle = #fopen("pastebin.html", "r");
if ($handle) {
while (!feof($handle)) {
$buffer = fgetss($handle, 4096);
echo $buffer;
}
fclose($handle);
}
?>
output is

You can probably write additional code to convert to spaces etc.
I'm not sure I did understand everything correctly but this seems to be your expected result:
$txt = file_get_contents('http://pastebin.com/raw.php?i=2Zgbs7hi');
var_dump(preg_replace("/(\ \;(\s{1,})?)+/", "\n", trim(strip_tags(preg_replace("/(\s){1,}/", " ", $txt)))));
//more readable
$txt = preg_replace("/(\s){1,}/", " ", $txt);
$txt = trim(strip_tags($txt));
$txt = preg_replace("/(\ \;(\s{1,})?)+/", "\n", $txt);
The strip_tags() function strips HTML and PHP tags from a string, if that is what you are trying to accomplish.
Examples from the docs:
<?php
$text = '<p>Test paragraph.</p><!-- Comment --> Other text';
echo strip_tags($text);
echo "\n";
// Allow <p> and <a>
echo strip_tags($text, '<p><a>');
?>
The above example will output:
Test paragraph. Other text
<p>Test paragraph.</p> Other text
I am trying to replace text between two tags in a html document. I want to replace any text that isn't enclosed with a < and >.
I want to use str_replace to do this.
php $string = '<html><h1> some text i want to replace</h1><p>some stuff i want to replace </p>';
$text_to_echo = str_replace("Bla","Da",$String);
echo $text_to_echo;
Try this:
<?php
$string = '<html><h1> some text i want to replace</h1><p>
some stuff i want to replace </p>';
$text_to_echo = preg_replace_callback(
"/(<([^.]+)>)([^<]+)(<\\/\\2>)/s",
function($matches){
/*
* Indexes of array:
* 0 - full tag
* 1 - open tag, for example <h1>
* 2 - tag name h1
* 3 - content
* 4 - closing tag
*/
// print_r($matches);
$text = str_replace(
array("text", "want"),
array('TEXT', 'need'),
$matches[3]
);
return $matches[1].$text.$matches[4];
},
$string
);
echo $text_to_echo;
str_replace() can not handle this
You will need regex or preg_replace for that
My code-
$input = "this text is for highlighting a text if it exists in a string. Let us check if it works or not";
$pattern ="/if/";
$replacement= "H1Fontbracket"."if"."H1BracketClose";
echo preg_replace($pattern, $replacement, $input);
Now the problem is that when i run this code, it splits into multiple lines, what else do i need to do so that i am able to get it in one line
Use str_replace rather than preg_replace. preg_replace will return an array of strings, and str_replace will just return the string:
echo str_replace($pattern, $replacement, $input);
What do you mean by multiple lines? Of course it'll show up as multiple lines on a webpage if you wrap the ifs in header tags. Headers are block elements. And more importantly, headers are headers. Not for highlighting text.
If you want to highlight something with HTML, you should probably use a span with a class, or you could use the HTML5 element mark:
$input = "this text is for highlighting a text if it exists in an iffy string.";
echo preg_replace('/\\bif\\b/', '<span class="highlighted">$0</span>', $input);
echo preg_replace('/\\bif\\b/', '<mark>$0</mark>', $input);
The \\b is to only match if words, and not just the if letters, which might be part of a different word. Then in your CSS you can decide how the marked words should show up:
.highlighted { background: yellow }
mark { background: yellow }
Or whatever. I would recommend that you read up a bit on how HTML and CSS works if you're going to make web pages :)
Try this
$input = "this text is for highlighting a text if
it exists in a string. Let us check if it works or not";
$pattern="if";
$replacement="<h1>". $pattern. "</h1>";
$input= str_replace($pattern,$replacement,$input);
echo "$input";
function highlight($str,$search){
$patterns = array('/\//', '/\^/', '/\./', '/\$/', '/\|/',
'/\(/', '/\)/', '/\[/', '/\]/', '/\*/', '/\+/',
'/\?/', '/\{/', '/\}/', '/\,/');
$replace = array('\/', '\^', '\.', '\$', '\|', '\(', '\)',
'\[', '\]', '\*', '\+', '\?', '\{', '\}', '\,');
$search = preg_replace($patterns, $replace, $search);
$search = str_replace(" ","|",$search);
return #preg_replace("/(^|\s)($search)/i",'${1}<span class=highlight>${2}</span>',$str);
}
For instance I have a string:
$string = '<div class="ImageRight" style="width:150px">';
which I want to transform into this:
$string = '<div class="ImageRight">';
I want to remove the portion
style="width:150px with preg_replace() where the
size 150 can vary, so the width can be
500px etc. aswell.
Also, the last part of the classname varies aswell, so the class can be ImageRight, ImageLeft, ImageTop etc.
So, how can I remove the style attribute completely from a string with the above mentioned structure, where the only things that varies is the last portion of the classname and the width value?
EDIT: The ACTUAL string I have is an entire html document and I don't want to remove the style attribute from the entire html, only from the tags which match the string I've shown above.
I think this is what you're after...
$modifiedHtml = preg_replace('/<(div class="Image[^"]+") style="[^"]+">/i', '<$1>', $html);
Remove completely.
$string = preg_replace("/style=\"width:150px\"/", "", $string);
Replace:
$string = preg_replace("/style=\"width:150px\"/", "style=\"width:500px\"", $string);
You can do it in two steps with
$place = 'Left';
$size = 500;
$string = preg_replace('/(?<=class="image)\W(?=")/',$place,$string);
$string = preg_replace('/(?<=style="width:)[0-9]+(?=")/',$size,$string);
Note: (?=...) is called a lookahead.
How about:
$string = preg_replace('/(div class="Image.+?") style="width:.+?"/', "$1", $string);
Simple:
$string = preg_replace('/<div class="Image(.*?)".*?>/i', '<div class="Image$1">', $string);
I am using this class to highlight the search keywords on a piece of text:
class highlight
{
public $output_text;
function __construct($text, $words)
{
$split_words = explode( " " , $words );
foreach ($split_words as $word)
{
$text = preg_replace("|($word)|Ui" ,
"<font style=\"background-color:yellow;\"><b>$1</b></font>" , $text );
}
$this->output_text = $text;
}
}
If
$text = "Khalil, M., Paas, F., Johnson, T.E., Su, Y.K., and Payer, A.F. (2008.) Effects of Instructional Strategies Using Cross Sections on the Recognition of Anatomical Structures in Correlated CT and MR Images. <i>Anatomical Sciences Education, 1(2)</i>, 75-83 "
which already contains HTML tags, and some of my search keywords are
$words = "Effects color"
The first look will highlight the word Effects, with <font style="background-color:yellow">Effect</font>, but the second loop will highlight the word color in the HTML tag. What should I do?
Is it possible to tell preg_replace to only highlight text when its not inside an alligator bracket?
Use a HTML parser to make sure that you only search through text.
You could use a CSS highlighted class instead and then use span tags, eg.
<span class="highlighted">word</span>
Then define your highlighted class in CSS. You could then exclude the word 'highlighted' from being valid in your search. Of course renaming the class to something obscure would help.
This also has the benefit of allowing you to change the highlight colour easily in the future, or indeed allowing the user to toggle it on and off by modifying the CSS.
Why use a loop?
function __construct($text, $words)
{
$split_words = preg_replace("\s+", "|", $words);
$this->output_text = preg_replace("/($split_words)/i" ,
"<font style=\"background-color:yellow; font-weight:bold;\">$1</font>" , $text );
}
A possible work-around would be to first wrap it with characters, which would (to 99%) not be a search input and replace those characters with the html tags after the 'foreach' loop:
class highlight
{
public $output_text;
function __construct($text, $words)
{
$split_words = explode(" ", $words);
foreach ($split_words as $word)
{
$text = preg_replace("|($word)|Ui", "%$1~", $text);
}
$text = str_replace("~", "</b></span>", str_replace("%", "<span style='background-color:yellow;'><b>", $text));
$this->output_text = $text;
}
}
