echo characters only in one line with explode function php - php

here is what i want to do
i am working with php explode function trying to limit characters it prints after defined condition
{
$result=http://php.net
new line characters i don't want to print
$links =explode("://",$result);
$nows=$links[1];
echo $nows;
}
as you can see the above code will print
php.net
new line characters i don't want to print
but instead i want to stop printing after
php.net

You can replace newline characters with nothing:
$nows = str_replace("\n", "", $links[1]);
$nows = str_replace("\r", "", $nows);
echo $nows;
If you want only what is printed on the first line, try this:
$result = "php.net
and some other text";
$nows = reset(explode("\n", str_replace("\r\n", "\n", $result)));

If the part you're looking after will always be in the first line:
$result="http://php.net
new line characters i don't want to print";
$links = explode("\n",$result);
/*
$links[0] ->http://php.net
$links[1] ->new line characters i don't want to print
*/
$links =explode("://",$links[0]);
$nows=$links[1];
echo $nows;
/*
php.net
*/
Anyway , Consider giving more details about your case in order to offer a better way.
For instance , maybe regex?

Try
$nows = trim( $links[1] );
TRIM() will remove newlines among other things
Manual page
EDIT:
Well now we have the actual situation which you say is :-
$result=http://php.net</br>nameserver:ns1</br>nameserver:ns2.
Try
$t = explode( '</br>', $result );
$t1 = explode ( '://', $t[0] );
echo $t1[1];
Just as a note, if it is you that is creating this string somewhere else </br> is not a valid html tag, it should be <br> or if you are using XHTML it should be <br />.

I want to echo php text but not between ()

I want to echo php text but not between (). Some thing like this =
<?php
$text = "Barry(male)";
echo $text;
?>
output =
Barry
How can i do this?
You can use preg_replace to substitute whatever is between parenthes (and the parentheses themselves) with an empty string. Like this:
<?php
$text = "Barry(male)";
echo preg_replace('#\(.*\)#', '', $text);
?>
Please note: since you didn't specify your string format, I'm assuming that the parenthesized text appears just once in the string and that there aren't nested parenthes. Otherwise, this doesn't work as expected.
Something like:
$text = "Barry(male)";
$split = explode("(", $text);
echo $split[0];
// "Barry"

How to add new line in php echo

The text of story content in my database is:
I want to add\r\nnew line
(no quote)
When I use:
echo nl2br($story->getStoryContent());
to replace the \r\n with br, it doesn't work. The browser still display \r\n. When I view source, the \r\n is still there and br is nowhere to be found also. This is weird because when I test the function nl2br with simple code like:
echo nl2br("Welcome\r\nThis is my HTML document");
it does work. Would you please tell me why it didn't work? Thank you so much.
The following snippet uses a technique that you may like better, as follows:
<?php
$example = "\n\rSome Kind\r of \nText\n\n";
$replace = array("\r\n", "\n\r", "\r", "\n");
$subs = array("","","","");
$text = str_replace($replace, $subs, $example );
var_dump($text); // "Some Kind of Text"
Live demo here
I doubt that you need "\n\r" but I left it in just in case you feel it is really necessary.
This works by having an array of line termination strings to be replaced with an empty string in each case.
I found the answer is pretty simple. I simply use
$text = $this->storyContent;
$text = str_replace("\\r\\n","<br>",$text);
$text = str_replace("\\n\\r","<br>",$text);
$text = str_replace("\\r","<br>",$text);
$text = str_replace("\\n","<br>",$text);

remove HTML from displaying in PHP

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 &nbsp 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 "&nbsp"
$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("/(\&nbsp\;(\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("/(\&nbsp\;(\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

remove all kind of tags from text

I am working on a project and I am facing a problem that "span>" also prints in the start of text I tried to remove all the tags every thing gone finely except the one i mentioned above,
here is my php code
<p>
<?php
$desc = $top_news['headline_des'];
$aa = preg_replace( '/style=(["\'])[^\1]*?\1/i', '', $desc, 2 );
if(strlen($top_news['headline_des'])>100)
{
$description = substr($aa, 1 ,850)."...";
}else{
$description = $aa;
}
echo strip_tags($description);
?>
</p>
here is the output
span >IPOR have the International Republican Institute (IRI) and the United States Agency for International....
The problem is the substr($aa, 1 ,850) call. substr starts with position 0, not 1, so what happens is this:
Input: <span>Foobar</span>
substr($input, 1, 850)
Output: span>Foobar</span>
substr cuts off happily the first char. Hence, strip_tags doesn't recognize span> as a whole tag and simply leaves it alone.
Fix: Use substr($aa, 0, 850).
$intro = ereg_replace("[</*>]", "", $intro);
$text = preg_replace("/<.+?>/", "", $text);
something like this should remove any tag in the $text variable.
If it doesn't work, you should check if the initial text you want to remove the tags from is correctly formed. For example a span > won't be removed since it isn't a tag, but a <span > would be removed without problem.
you could use strip_tags only for removing tags
With preg_replace
$desc = $top_news['headline_des'];
$search = array(
'#<style[^>]*?>.*?</style>#siU',
'#<[\/\!]*?[^<>]*?>#si'
);
echo $pregReplacedContent = preg_replace($search, "", $aa);

I need to split text delimited by paragraph tag

$text = "<p>this is the first paragraph</p><p>this is the first paragraph</p>";
I need to split the above into an array delimited by the paragraph tags. That is, I need to split the above into an array with two elements:
array ([0] = "this is the first paragraph", [1] = "this is the first paragraph")
Remove the closing </p> tags as we don't need them and then explode the string into an array on opening </p> tags.
$text = "<p>this is the first paragraph</p><p>this is the first paragraph</p>";
$text = str_replace('</p>', '', $text);
$array = explode('<p>', $text);
To see the code run please see the following codepad entry. As you can see this code will leave you with an empty array entry at index 0. If this is a problem then it can easily be removed by calling array_shift($array) before using the array.
For anyone else who finds this, don't forget that a P tag may have styles, id's or any other possible attributes so you should probably look at something like this:
$ps = preg_split('#<p([^>])*>#',$input);
This is an old question but I was not able to find any reasonable solution in an hour of looking for stactverflow answers. If you have string full of html tags (p tags) and if you want to get paragraphs (or first paragraph) use DOMDocument.
$long_description is a string that has <p> tags in it.
$long_descriptionDOM = new DOMDocument();
// This is how you use it with UTF-8
$long_descriptionDOM->loadHTML((mb_convert_encoding($long_description, 'HTML-ENTITIES', 'UTF-8')));
$paragraphs = $long_descriptionDOM->getElementsByTagName('p');
$first_paragraph = $paragraphs->item(0)->textContent();
I guess that this is the right solution. No need for regex.
edit: YOU SHOULD NOT USE REGEX TO PARSE HTML.
$text = "<p>this is the first paragraph</p><p>this is the first paragraph</p>";
$exptext = explode("<p>", $text);
echo $exptext[0];
echo "<br>";
echo $exptext[1];
//////////////// OUTPUT /////////////////
this is the first paragraph
this is the first paragraph
Try this code:
<?php
$textArray = explode("<p>" $text);
for ($i = 0; $i < sizeof($textArray); $i++) {
$textArray[$i] = strip_tags($textArray[$i]);
}
If your input is somewhat consistent you can use a simple split method as:
$paragraphs = preg_split('~(</?p>\s*)+~', $text, PREG_SPLIT_NO_EMPTY);
Where the preg_split will look for combinations of <p> and </p> plus possible whitespace and separate the string there.
As unnecessary alternative you can also use querypath or phpquery to extract only complete paragraph contents using:
foreach (htmlqp($text)->find("p") as $p) { print $p->text(); }
Try the following:
<?php
$text = "<p>this is the first paragraph</p><p>this is the first paragraph</p>";
$array;
preg_replace_callback("`<p>(.+)</p>`isU", function ($matches) {
global $array;
$array[] = $matches[1];
}, $text);
var_dump($array);
?>
This can be modified, putting the array in a class that manage it with an add value method, and a getter.
Try this.
<?php
$text = "<p>this is the first paragraph</p><p>this is the first paragraph</p>";
$array = json_decode(json_encode((array) simplexml_load_string('<data>'.$text.'</data>')),1);
print_r($array['p']);
?>
