Summary of string usage in php_PHP tutorial

1 Find the length, the most basic
$text = "sunny day";
$count = strlen($text); // $count = 9


2 String interception
How many characters before interception
$article = "BREAKING NEWS: In ultimate irony, man bites dog."; $summary = substr_replace($article, ".. .", 40);

3 Count the number of words
$article = "BREAKING NEWS: In ultimate irony, man bites dog."; $wordCount = str_word_count($article) ;
// $wordCount = 8

4 Concatenation to convert string into HTML
$url = "W.J. Gilmore, LLC (http://www.jb51 .net)";
$url = preg_replace("/http://([A-z0-9./-]+)/", "$0", $url);

5 Remove HTML string from characters
$text = strip_tags($input, "
");

6 nl2br:
$comment = nl2br($comment );
Convert to HTML format

7 Wordwrap
Limit the number of words per line
$speech = "Four score and seven years ago our fathers brought forth, upon this continent, a new nation , conceived in Liberty, and dedicated to the proposition that all men are created equal.";
echo wordwrap($speech, 30);

Output:
Four score and seven years ago our fathers brought forth, upon this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.
