我想將文本中的所有網(wǎng)址設(shè)為超鏈接。我做了以下事情。但鏈接缺少“：”。任何幫助表示贊賞。<?php$string = "Hallo Studenten http://google.com/your/subpage and https://www.yahoo.com/my/subpage"; $regexp = "/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i"; $anchorMarkup = "<a href=\"%s://%s\" target=\"_blank\" >%s</a>"; preg_match_all($regexp, $string, $matches, \PREG_SET_ORDER); foreach ($matches as $match) { if (empty($match[1]) && empty($match[7])) { $http = $match[2]?$match[2]:'http'; $replace = sprintf($anchorMarkup, $http, $match[0], $match[0], $match[1]); $string = str_replace($match[0], $replace, $string); } } echo $string; ?>http://phpfiddle.org/lite/code/2yg5-i3uj

可以使用preg_replace函數(shù)來完成：
$string? ? ? ?= "Hallo Studenten http://google.com/your/subpage and https://www.yahoo.com/my/subpage";
$regexp? ? ? ?= "/\b(?:(?:https?|ftp):\/\/|www\.)[-a-z0-9+&@#\/%?=~_|!:,.;]*[-a-z0-9+&@#\/%=~_|]/i";
$anchorMarkup = "<a href=\"$0\" target=\"_blank\" >$0</a>";
echo preg_replace($regexp, $anchorMarkup, $string);
