Summary of string usage in PHP

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


2 string interception

$article = "BREAKING NEWS: In ultimate irony, man bites dog."; $summary = substr_replace ($article, "..." , 40);

$article = "BREAKING NEWS: In ultimate irony, man bites dog."; $wordCount = str_word_count ($article);
/ / $wordCount = 8

$url = "W.J. Gilmore, LLC (//www.jb51.net)";
$url = preg_replace ("/http:// (A - z0-9. / - +)/", "$0, $url);
