我想有一个函数从Unicode字符串创建鼻涕虫,例如gen_slug('Andrés Cortez')应该返回andres-cortez。我该怎么做呢?
当前回答
如果你的弹头只包含A-Za-z0-9-那么这对你来说是可以的
function sanitize_slug($text)
{
$text = preg_replace('/[^A-Za-z0-9-]+/', '-', $text);
$text = trim($text, '-');
$text = preg_replace('~-+~', '-', $text);
return $text;
}

注意:我已经从wordpress和它的工作!!
像这样使用它:
echo sanitize('testing this link');
Code
//taken from wordpress
function utf8_uri_encode( $utf8_string, $length = 0 ) {
$unicode = '';
$values = array();
$num_octets = 1;
$unicode_length = 0;
$string_length = strlen( $utf8_string );
for ($i = 0; $i < $string_length; $i++ ) {
$value = ord( $utf8_string[ $i ] );
if ( $value < 128 ) {
if ( $length && ( $unicode_length >= $length ) )
break;
$unicode .= chr($value);
$unicode_length++;
} else {
if ( count( $values ) == 0 ) $num_octets = ( $value < 224 ) ? 2 : 3;
$values[] = $value;
if ( $length && ( $unicode_length + ($num_octets * 3) ) > $length )
break;
if ( count( $values ) == $num_octets ) {
if ($num_octets == 3) {
$unicode .= '%' . dechex($values[0]) . '%' . dechex($values[1]) . '%' . dechex($values[2]);
$unicode_length += 9;
} else {
$unicode .= '%' . dechex($values[0]) . '%' . dechex($values[1]);
$unicode_length += 6;
}
$values = array();
$num_octets = 1;
}
}
}
return $unicode;
}
//taken from wordpress
function seems_utf8($str) {
$length = strlen($str);
for ($i=0; $i < $length; $i++) {
$c = ord($str[$i]);
if ($c < 0x80) $n = 0; # 0bbbbbbb
elseif (($c & 0xE0) == 0xC0) $n=1; # 110bbbbb
elseif (($c & 0xF0) == 0xE0) $n=2; # 1110bbbb
elseif (($c & 0xF8) == 0xF0) $n=3; # 11110bbb
elseif (($c & 0xFC) == 0xF8) $n=4; # 111110bb
elseif (($c & 0xFE) == 0xFC) $n=5; # 1111110b
else return false; # Does not match any model
for ($j=0; $j<$n; $j++) { # n bytes matching 10bbbbbb follow ?
if ((++$i == $length) || ((ord($str[$i]) & 0xC0) != 0x80))
return false;
}
}
return true;
}
//function sanitize_title_with_dashes taken from wordpress
function sanitize($title) {
$title = strip_tags($title);
// Preserve escaped octets.
$title = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '---$1---', $title);
// Remove percent signs that are not part of an octet.
$title = str_replace('%', '', $title);
// Restore octets.
$title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title);
if (seems_utf8($title)) {
if (function_exists('mb_strtolower')) {
$title = mb_strtolower($title, 'UTF-8');
}
$title = utf8_uri_encode($title, 200);
}
$title = strtolower($title);
$title = preg_replace('/&.+?;/', '', $title); // kill entities
$title = str_replace('.', '-', $title);
$title = preg_replace('/[^%a-z0-9 _-]/', '', $title);
$title = preg_replace('/\s+/', '-', $title);
$title = preg_replace('|-+|', '-', $title);
$title = trim($title, '-');
return $title;
}
因为我在这里看到了很多方法,但我为自己找到了一个最简单的方法。也许它会帮助别人。
$slug = strtolower(preg_replace('/[^a-zA-Z0-9\-]/', '',preg_replace('/\s+/', '-', $string) ));
不确定它适用于每一种情况,但我从Laravel Str类中采用了slug方法,并添加了iconv('utf-8', 'us-ascii//TRANSLIT', $title)的东西来处理口音,而不需要使用voku/便携式ascii,这似乎对我的用例工作得很好:
public static function slug($title, $separator = '-')
{
$title = iconv('utf-8', 'us-ascii//TRANSLIT', $title);
$flip = $separator === '-' ? '_' : '-';
$title = preg_replace('!['.preg_quote($flip).']+!u', $separator, $title);
// Replace @ with the word 'at'
$title = str_replace('@', $separator.'at'.$separator, $title);
// Remove all characters that are not the separator, letters, numbers, or whitespace.
$title = preg_replace('![^'.preg_quote($separator).'\pL\pN\s]+!u', '', mb_strtolower($title, 'UTF-8'));
// Replace all separator characters and whitespace by a single separator
$title = preg_replace('!['.preg_quote($separator).'\s]+!u', $separator, $title);
return trim($title, $separator);
}
与其用冗长的替换,不如试试下面这个:
public static function slugify($text, string $divider = '-')
{
// replace non letter or digits by divider
$text = preg_replace('~[^\pL\d]+~u', $divider, $text);
// transliterate
$text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
// remove unwanted characters
$text = preg_replace('~[^-\w]+~', '', $text);
// trim
$text = trim($text, $divider);
// remove duplicate divider
$text = preg_replace('~-+~', $divider, $text);
// lowercase
$text = strtolower($text);
if (empty($text)) {
return 'n-a';
}
return $text;
}
这是基于Symfony的Jobeet教程。

$clean = preg_replace("/[^a-zA-Z0-9\/_|+ -]/", '', $clean);
$clean = strtolower($clean);
$clean = preg_replace("/[\/_|+ -]+/", $delimiter, $clean);
$clean = trim($clean, $delimiter);
setlocale(LC_ALL, $oldLocale);
return $clean;
