搜索引擎友好URL(SEF/SEO)

Question

我想将友好的URL名称转换为:

Tom's Fish&Chips
Slug:tom-fish-and-Chips

1-2-3披萨
slu :: 1-2-3-Pizza

这里有一个功能:

<?php

function urlTitle($title) {
    $title = preg_replace("/(.*?)([A-Za-z0-9\s]*)(.*?)/", "$2", $title);
    $title = str_replace(' ', '-', $title);
    $title = strtolower($title);
    return $title;
}

echo urlTitle("Tom's Fish & Chips");
echo "<br />";
echo urlTitle("1-2-3 Pizza");

?>

上面这个函数的行为几乎就是我想要的,因为我得到:

toms-fish--chips
123-pizza

我该如何解决？

Answer 1

function seo($input){
    $input = str_replace(array("'", "-"), "", $input); //remove single quote and dash
    $input = mb_convert_case($input, MB_CASE_LOWER, "UTF-8"); //convert to lowercase
    $input = preg_replace("#[^a-zA-Z0-9]+#", "-", $input); //replace everything non an with dashes
    $input = preg_replace("#(-){2,}#", "$1", $input); //replace multiple dashes with one
    $input = trim($input, "-"); //trim dashes from beginning and end of string if any
    return $input; //voila
}

第二个preg_replace用一个替换多个破折号.

例子:

echo seo("Tom's Fish & Chips"); //toms-fish-chips
echo seo("1-2-3 Pizza"); //123-pizza
