is it possible with php's wordwrap to add increased indentation each line break to essentially create wordwrapping on an angle?
If I understand your question correcly, you would like to produce an output like:
xxxxxxx
xxxxxxxxx
xxxxxxxxxxx
xxxxxxxxxxxxx
xxxxxxxxxxxxxxx
Obviously, replacing x with your text.
wordwrap built-in function does not support this feature but you still can write your own, with a simple loop. Change the max length on each iteration, and break your initial string (depending on your needs, where you find a space or wherever you want).
<?php
$text = "The quick brown fox jumped over the lazy dog.";
echo $return = costomwrap($text , 10);
function costomwrap($text , $len)
{
$str = '';
for($i=0;$i<strlen($text);$i = $i+$len)
{
$str .= substr($text , $i , $len ).'<br />';
$len--;
}
return $str;
}
?>

I want to like add space in sting with specified string length.
For example : Hello is my string & i set string length 30 so next string should be start after length 30 so it should be like Hello Next string.
I would like to add space..
I have used following code but it's not adding space it's take whole character but not added space.
<?php
$fistString ="Hello World";
$secondString ="Good";
echo str_pad($fistString, 45, ' ', STR_PAD_RIGHT).$secondString;
?>
it will be done by using this
$string_1 = "The quick brown fox jumped over the lazy dog.";
$string_2= " -space-or-anything- ";
$newtext = wordwrap($string_1, 20, " $string_2 <br>");
// it will add second string after every 20th character and also break the line
echo $newtext;
// result will be like
The quick brown fox -space-or-anything-
jumped over the lazy -space-or-anything-
dog.
as per my knowledge the answer is :-
<?php
$fistString ="Hello World";
$secondString ="Good";
$str=$fistString;
for ($i=0; $i < 30; $i++) {
$str.=' ';
}
$str.=$secondString;
echo $str;
?>
I did with my self with following way..
<?php
echo str_pad($string, 30, "  ", STR_PAD_RIGHT).$secondString;
?>
Add space with specified string length in php
$temp ="optionA"
chunk_split($temp ,6,' ')
output : option A
I am trying to have this ORIGINAL string converted to the RESULT below using php.
ORIGINAL: "The quick <font color="brown">brown</font> fox jumps over the lazy dog"
RESULT:"god yzal eht revo spmuj xof <font color="brown">nworb</font> kciuq ehT"
What I have done so far is explained like below.
First, strip the HTML tag from the ORIGINAL.
$originalStr = "The quick <font color='brown'>brown</font> fox jumps over the lazy dog";
$stripTags = strip_tags($originalStr);
This results to The quick brown fox jumps over the lazy dog ,
Second, I reverse the result and the word "brown" by using strrev function
$reverseStr = strrev($stripTags);
$brown = strrev("brown");
This results to god yzal eht revo spmuj xof nworb kciuq ehT
Third, I am trying to use str_replace function to find $brown from the reverseStr, and replace it with $openFont $brown $closeFont like below.
$openFont = "<font color='brown'>";
$closeFont = "</font>";
$result = str_replace($brown, $openFont.$brown.$closeFont, $reverseStr);
echo "result -->" . $result . "<br/><br/><br/>";
This results to god yzal eht revo spmuj xof kciuq ehT, NOT the same as the RESULT.
It seems like special characters in font () tag is the problem that may be blocking str_replace to replace the String.
$result = str_replace($brown, "TEST", $reverseStr);
echo "result -->" . $result . "<br/><br/><br/>";
This results to god yzal eht revo spmuj xof TEST kciuq ehT
Does anyone know str_replace is not accepting special characters? and know how I should solve this problem?
If there is another way to solve the problem, I will also be appreciated to hear your suggestion.
(* This is one of the practical questions that I am trying to solve in an algorithm test websites)
UPDATED: I feel so dumb to think that where font tag was. Since tag is meant to change the font color, it was working perfectly in the beginning. Thank you very much everyone for your time!
If it was me, I'd do this (fully tested):
// Original string
$str = 'The quick <font color="brown">brown</font> fox jumps over the lazy dog';
// Strip the font tag
$str = strip_tags( $str );
// Convert string to array
$arr = str_split( $str );
// Reverse the array
$rra = array_reverse( $arr );
// Convert array back to string
$str = implode( $rra );
// Add font tag back in
$str = str_replace('nworb', '<font color="brown">nworb</font>', $str);
// Result
echo $str;
Parse the HTML with something that will give you a DOM API to it.
Write a function that loops over the child nodes of an element.
If a node is a text node, get the data as a string, split it on words, reverse each one, then assign it back.
If a node is an element, recurse into your function.
Use preg_match_all() function.
$originalStr = "The quick <font color='brown'>brown</font> fox jumps over the lazy dog";
preg_match_all('|<[^>]+>(.*)</[^>]+>|U', $originalStr, $matches, PREG_SET_ORDER, 0);
$_tag = $matches[0][0];
$_txt = $matches[0][1];
$newString = str_replace($_tag,$_txt,$originalStr);
I have an application that can only deal with text up to 100 characters in length per line.
However I do not want to be splitting mid-word in a sentence as that doesn't look very nice. Therefore we would need to find the space before the 100th Character and then add it into the array.
I was thinking using strrpos would work - but am unsure how to do the continuing so it has everything in one array
$textToDraw = 'this is a message that is over 100 characters long just to see how well that the breaks work';
$characterLimit = substr($textToDraw, 0, 100);
$textBeforeLimit = strrpos($characterLimit, ' ', 0);
Thanks
UPDATE. This is the current code I have to split the text into an array and then draw each line. However I need it to cut on the space before 100 characters - and not on a hardcoded 100 character limit.
for ($i = 0; $i < count($textToDraw); $i++) {
$splitPoint = 100;
if ( strlen($textToDraw[$i]) > $splitPoint ) {
$newTextLines = str_split($textToDraw[$i], $splitPoint);
array_splice($textToDraw, $i, 1, $newTextLines);
$i = $i + count($newTextLines) - 1;
}
}
foreach ($textToDraw as $actualTextToDraw) {
$page->drawText($actualTextToDraw, $this->x , $this->y , 'UTF-8');
}
You can use php function wordwrap as below. This Wraps a string to a given number of characters using a string break character.
<?php
$textToDraw = 'this is a message that is over 100 characters long just to see how well that the breaks work';
$newtext = wordwrap($textToDraw, 100, "<br />\n");
echo $newtext;
?>
Try wordwrap().
Wraps a string to a given number of characters using a string break character.
Example adapted from the documentation page:
<?php
$text = "The quick brown fox jumped over the lazy dog.";
$newtext = wordwrap($text, 20, "<br />\n");
echo $newtext;
// Outputs:
// The quick brown fox<br />
// jumped over the lazy<br />
// dog.
Update for new info in question:
Apply it to your needs:
$text = "Here's some example text that may or may not be really really long.";
$linedText = wordwrap($text, 20, "\n");
$lines = explode("\n", $linedText);
// Do whatever with $lines.
I have this code:
$string = 'The quick brown fox jumped over the lazy dog and lived to tell about it to his crazy moped.';
$text = explode("#", str_replace(" ", " #", $string)); //ugly trick to preserve space when exploding, but it works (faster than preg_split)
foreach ($text as $value) {
echo preg_replace_callback("/(.*p.*e.*d.*|.*a.*y.*)/", function ($matches) {
return " <strong>".$matches[0]."</strong> ";
}, $value);
}
The point of it is to be able to enter a sequence of characters (in the code above it's a fixed pattern), and it finds and highlights those characters in the matched word. The code I have now highlights the entire word. I'm looking for the most efficient way of highlighting the characters.
The result of the current code:
The quick brown fox jumped over the lazy dog and lived to tell about it to his crazy moped.
What I would like to have:
The quick brown fox jumped over the lazy dog and lived to tell about it to his crazy moped.
Did I take the wrong approach? It would be awesome if someone could point me in the right way, I've been searching for hours and didn't find what I was looking for.
EDIT 2:
Divaka's been a great help. Almost there.. I apologize if I haven't been clear enough on what my goal is. I will try to explain further.
- Part A -
One of the things I will be using this code for is a phone book. A simple example:
When following characters are entered:
Jan
I need it to match following examples:
Jan Verhoeven
Arjan Peters
Raj Naren
Jered Von Tran
The problem is that I will be iterating over the entire phone book, person-record per person-record. Each person also has email-addresses, a postal address, maybe a website, a extra note, ect.. This means that the text I'm actually search can contain anything from letters, numbers, special characters(&#()%_- etc..), newlines, and most importantly spaces. So an entire record (csv) might contain the following info:
Name;Address;Email address;Website;Note
Jan Verhoeven;Veldstraat 2a, 3209 Herkstad;jan#werk.be;www.janophetwerk.be,jan#telemet.be;Jan die ik ontmoet heb op de bouwbeurs.\n Zelfstandige vertegenwoordiger van bouwmaterialen.
Raj Naren;Kerklaan 334, 5873 Biep;raj#werk.be;;Rechtstreekse contactpersoon bij Werk.be (#654 intern)
The \n is meant to be an actual newline. So if I search for #werk.be, I'd like to see both these records as a result.
- Part B -
Something else I want to use this for is searching song-texts. When I'm looking for a song and I can only remember it had to do something with ducks or docks and a circle, I would enter dckcircle and get the following result:
... and the ducks were all dancing in a great big circle, around the great big bonfire ...
To be able to fine-tune the searching I'd like to be able to limit the number of spaces (or any other character), because I would imagine it finding a simple pattern like eve in every song while I'm only looking for a song that has the exact word eve in it.
- Conclusion -
If I summarize this in pseudo-regex, for a search pattern abc with a max of 3 spaces in-between it would be something like this: (I might be totally off here)
(a)(any character, max 3 spaces)(b)(any character, max 3 spaces)(c)
Or more generic:
(a)({any character}{these characters with a limit of 3})(b)({any character}{these characters with a limit of 3})(c)
This can even be extended to this fairly easily I'm guessing:
(a)({any character}{these characters with a limit of 3}{not these characters})(b)({any character}{these characters with a limit of 3}{not these characters})(c)
(I know the ´{}´ brackets are not to be used that way in a regular expression, but I don't know how else to put it without using a character that has a meaning in regular expressions.)
If anyone wonders, I know the sql like statement would be able to do 80% (I'm guessing, might even be more) of what I'm trying to do, but I'm trying to avoid using a database to make this as portable as possible.
When the correct answer has been found, I'll clean this question (and the code) up and post the resulting php-class here (maybe I'll even put it up on github if that would be useful), so anyone looking for the same will have a fully working class to work with :).
I've came up with this. Tell me if it's what you want!
//$string = "The quick brown fox jumped over the lazy dog and lived to tell about it to his crazy moped.";
$string = "abcdefo";
//$pattern_array1 = array(a,y);
//$pattern_array2 = array(p,e,d);
$pattern_array1 = array(e,f);
$pattern_array2 = array(o);
$pattern_array2 = array(a,f);
$number_of_patterns = 2;
$regexp1 = generate_regexp($pattern_array1, 1);
$regexp2 = generate_regexp($pattern_array2, 2);
$string = preg_replace($regexp1["pattern"], $regexp1["replacement"], $string);
$string = preg_replace($regexp2["pattern"], $regexp2["replacement"], $string);
$string = transform_multimatched_chars($string);
// transforming other chars after transforming the multimatched ones
for($i = 1; $i <= $number_of_patterns; $i++) {
$string = str_replace("#{$i}", "<strong>", $string);
$string = str_replace("#/{$i}", "</strong>", $string);
}
echo $string;
function generate_regexp($pattern_array, $pattern_num) {
$regexp["pattern"] = "/";
$regexp["replacement"] = "";
$i = 0;
foreach($pattern_array as $key => $char) {
$regexp["pattern"] .= "({$char})";
$regexp["replacement"] .= "#{$pattern_num}\$". ($key + $i+1) . "#/{$pattern_num}";
if($key < count($pattern_array) - 1) {
$regexp["pattern"] .= "(?s)((?:(?!{$pattern_array[$key + 1]})(?!\s).)*)";
$regexp["replacement"] .= "\$".($key + $i+2) . "";
}
$i = $key + 1;
}
$regexp["pattern"] .= "/";
return $regexp;
}
function transform_multimatched_chars($string)
{
preg_match_all("/((#[0-9]){2,})(.*)((#\/[0-9]){2,})/", $string, $matches);
// change this for your purposes
$start_replacement = '<span style="color:red;">';
$end_replacement = '</span>';
foreach($matches[1] as $key => $match)
{
$string = str_replace($match, $start_replacement, $string);
$string = str_replace($matches[4][$key], $end_replacement, $string);
}
return $string;
}
I'm familiar with PHP truncating text based on the maximum number of characters reached, however I am wanting to tweak this from characters to limit text to 10 lines before truncating it.
How could I go about in achieving this?
Here is what I'm using at the moment to limit the number of characters:
<?php $str = $profile['bio'];
$max = 510;
if(strlen($str) > $max) {
$str = substr($str, 0, $max) . '...'; } ?>
<?php echo $str ?>
Use explode() to turn the text into an array of lines, array_slice() to limit the amount of lines, and then implode() to put it all back together again:
<?php
$text = "long\nline\ntext\nhere";
$lines = explode("\n", $text);
$lines = array_slice($lines, 0, 10); //10 is how many lines you want to keep
$text = implode("\n", $lines);
?>
I think your best bet is to use pure css to limit the height of your text/container.
What is a "line" of text?
Pure text written in a form field?
Text from editor perhaps full of html tags inside?
Utf8 text with foreign characters?
I fail to see a common pattern to the phrase "line of text" so as to use whatever method to limit its length (thus its height).
If you still want to limit it with php, then i suggest using length limiters. There are countless posts here and on the web in general. But you should be careful of encoded data (non latin ones)
e.g.
<?php
$subject = data();
$p = "![\r\n]+!";
$subject = preg_split($p, $subject, 11);
$subject = array_slice($subject, 0, 10);
echo join("\r\n", $subject);
function data() {
return <<< eot
Mary had a little lamb,
whose fleece was white as snow.
And everywhere that Mary went,
the lamb was sure to go.
It followed her to school one day
which was against the rule.
It made the children laugh and play,
to see a lamb at school.
And so the teacher turned it out,
but still it lingered near,
And waited patiently about,
till Mary did appear.
"Why does the lamb love Mary so?"
the eager children cry.
"Why, Mary loves the lamb, you know."
the teacher did reply.
eot;
}
prints

You can use this function:
<?php
// Original PHP code by Chirp Internet: www.chirp.com.au
// Please acknowledge use of this code by including this header.
function truncateLongText ($string, $limit, $break=".", $pad="...") {
// return with no change if string is shorter than $limit
$string = strip_tags($string, '<b><i><u><a><s><br><strong><em>');
if(strlen($string) <= $limit)
return $string;
// is $break present between $limit and the end of the string?
if ( false !== ($breakpoint = strpos($string, $break, $limit)) ) {
if($breakpoint < strlen($string) - 1) {
$string = substr($string, 0, $breakpoint) . $pad;
}
}
return $string;
}
Example usage:
$text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book.";
echo truncateLongText($text, 10);
// Lorem Ipsum is simply dummy text of the printing and typesetting industry...
