Highlight text if preg_match dot(.)

[balkan7]

Hi guys

I need highlight text from variable like this one:

 

$text = "Quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat.";

  If preg_match first dot in text i want replace it like this bellow:

 

  Quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

  Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat.

So, basically you want to add a newline after the first period?

 

No need for regular expressions for this one, str_replace handles that just fine:

$text = str_replace ('. ', ".\n", $text, 1);

Or, upon re-reading your post. Seems like you want to add bold tags to it too. (Instead?)

If so, then you'd need a RegExp. Only, not preg_match, but preg_replace:

$regExp = '/^([^.]+)\\./';
$replace = '<strong>$1</strong>.';
$text = preg_replace ($regExp, $replace, $text);

Tested and working, but if exist date like 05.10.2011 highlighting stop in 05. can be this skip ?

 

And text separated with two variables:

$highlighted = "Quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.";
$more = "Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat."; 

[Christian F.]

Yes, to both of those.

 

For the first, just add a space after the period in the RegExp. Should handle dates just fine then.

 

For the second, just use explode on the string, on '. ', restricted to one match. That would be the easiest way.

Please example with regex

I'm trying this one but doesn't work

$regExp = '/^([^.]+)\\.\s/';

[Christian F.]

Define "doesn't work"?

[balkan7]

$text= "Quis nostrud 05.10.2011 exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat.";
$regExp = '/^([^.]+)\\.\s/';
$replace = '<strong>$1</strong>.';
$text = preg_replace ($regExp, $replace, $text);
$test = explode(".", $text);
$display1 = nl2br($test[0]);
$display2 = nl2br($test[1]);

Result is: Quis nostrud 0510  (without apply tags <strong>)

[Christian F.]

Ah, now I see.

Change the [^.]+ part to .*?, and it should work.

 

Also, you missed a character in the string I said you needed to explode on. Which is why you're only getting the first part of the date, instead of the first line, after the explode.

Result for dates is: Quis nostrud 0510

Result for non dates is: Quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat.

Yes, ref: My second sentence.

balkan7, are you able to install PECL extensions? I only ask because as part of the Intl extension (and to be bundled with PHP 5.5) are some classes to make tasks like breaking up text into sentences super-easy. If you can, putting them to use would mean installing Intl 3 (currently 3.0.0b1) via

pecl install intl-beta

Then, playtime!

<?php

$text = 'Quis nostrud 05.10.2011 exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat. Aenean vel arcu at libero vestibulum bibendum. Integer sit amet lacus nibh, viverra feugiat ante. Ut justo libero, venenatis at tincidunt eget, dapibus vitae velit. Aliquam tempor, urna sed bibendum pharetra, metus diam vestibulum augue, sed adipiscing tortor ante vitae lacus. Donec congue egestas ipsum, sit amet porta lectus pellentesque at. ';

$sentence_iterator = IntlBreakIterator::createSentenceInstance('en');
$sentence_iterator->setText($text);
$sentences = iterator_to_array($sentence_iterator->getPartsIterator());

var_export($sentences);

?>

 

This shows that $sentences is an array:

 

array (
0 => 'Quis nostrud 05.10.2011 exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. ',
1 => 'Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat. ',
2 => 'Aenean vel arcu at libero vestibulum bibendum. ',
3 => 'Integer sit amet lacus nibh, viverra feugiat ante. ',
4 => 'Ut justo libero, venenatis at tincidunt eget, dapibus vitae velit. ',
5 => 'Aliquam tempor, urna sed bibendum pharetra, metus diam vestibulum augue, sed adipiscing tortor ante vitae lacus. ',
6 => 'Donec congue egestas ipsum, sit amet porta lectus pellentesque at. ',
)
