Text¶

The TextHelper contains methods to make text more usable and friendly in your views. It aids in enabling links, formatting urls, creating excerpts of text around chosen words or phrases, highlighting key words in blocks of text, and to gracefully truncating long stretches of text.

autoLinkEmails (string $text, array $htmlOptions=array())

Adds links to the well-formed email addresses in $text, according to any options defined in $htmlOptions (see HtmlHelper::link()).

$my_text = 'For more information regarding our world-famous pastries and desserts, contact [email protected]';
$linked_text = $text->autoLinkEmails($my_text);

//$linked_text:
For more information regarding our world-famous pastries and desserts,
contact <a href="mailto:[email protected]"><u>info@example.com</u></a>

autoLinkUrls (string $text, array $htmlOptions=array())

Same as in autoLinkEmails(), only this method searches for strings that start with https, http, ftp, or nntp and links them appropriately.

autoLink (string $text, array $htmlOptions=array())

Performs the functionality in both autoLinkUrls() and autoLinkEmails() on the supplied $text. All URLs and emails are linked appropriately given the supplied $htmlOptions.

excerpt (string $haystack, string $needle, int $radius=100, string $ending=»…»)

Extracts an excerpt from $haystack surrounding the $needle with a number of characters on each side determined by $radius, and suffixed with $ending. This method is especially handy for search results. The query string or keywords can be shown within the resulting document.

<?php echo $text->excerpt($last_paragraph, 'method', 50); ?>
//Output
mined by $radius, and suffixed with $ending. This method is especially handy for
search results. The query...

highlight (string $haystack, string $needle, $highlighter= “<span class=»highlight»>\1</span >”)

Highlights $needle in $haystack using the $highlighter string specified.

<?php echo $text->highlight($last_sentence, 'using'); ?>
//Output
Highlights $needle in $haystack <span class="highlight">using</span>
the $highlighter string specified.

stripLinks ($text)

Strips the supplied $text of any HTML links.

toList (array $list, $and=”and”)

Creates a comma-separated list where the last two items are joined with ‘and’.

<?php echo $text->toList($colors); ?>

// Output
red, orange, yellow, green, blue, indigo and violet

truncate (string $text, int $length=100, string $ending=”…”, boolean $exact=true, boolean $considerHtml=false)

truncate (string $text, int $length=100, array $options=array(string $ending=”…”, boolean $exact=true, boolean $considerHtml=false))

trim(); // an alias for truncate

Cuts a string to the $length and suffix with $ending if the text is longer than $length. If $exact is passed as false, $text will not be cut mid-word and the truncation will occur after the previous word ending. If $considerHtml is passed as true, html tags will be respected and will not be cut off.

<?php
echo $text->truncate(
    'The killer crept forward and tripped on the rug.',
    22,
    '...',
    false
);
?>

//Output:
The killer crept...
