Question

所以我有以下字符串

/home/design/Baie/Design-Interior-Baie-019.jpg

现在有办法搜索单词Baie并找回这样的字符串：

/home/design/Baie/

我试图建立一个面包屑

Answer 1

您可以使用dirname返回您要查找的内容

    echo dirname('/home/design/Baie/Design-Interior-Baie-019.jpg');

Answer 2

var abcd = "/home/design/Baie/Design-Interior-Baie-019.jpg"
//Search
var n = abcd.search("Baie");
//split provide sub string
var xyz = abcd.split('Design');

consol.log(xyz[0])

或PHP

$abcd = "/home/design/Baie/Design-Interior-Baie-019.jpg";
$xyz = explode('Design', $abcd);
print_r($xyz)

Answer 3

在PHP中，假设您的面包屑在第一次出现时结束了＆＃34; Baie＆＃34;在你的道路上：

$search = "Baie" ;
$path = "/home/design/Baie/Design-Interior-Baie-019.jpg" ;
$breadcrumb = substr($path, 0, stripos($path, $search . "/")+strlen($search)+1 );
print $breadcrumb ;

Answer 4

$str = '/home/design/Baie/Design-Interior-Baie-019.jpg';
$search = 'Baie/';
$pos = strpos($str, $search);
$result = '';
if ($pos !== false) {
    $result = substr($str, 0, $pos + strlen($search));
}

print_r($result);

Answer 5

使用dirname()功能

dirname('/home/design/Baie/Design-Interior-Baie-019.jpg');

或者您也可以尝试

<?php

$word = 'Baie'; 

$string = "/home/design/Baie/Design-Interior-Baie-019.jpg";

$bread =  explode( "$word", $string);

echo $bread[0]."/$word/";

?>

Answer 6

在带有indexOf和slice的JavaScript中：

var str = "/home/design/Baie/Design-Interior-Baie-019.jpg";
var search = "Baie"
if (str.indexOf(search) != -1 )
   var result = str.slice(0,str.indexOf(search)+search.length+1);
console.log(result); // /home/design/Baie/

Answer 7

正则表达式怎么样？

<?php
$array=[];
$path="/home/design/Baie/Design-Interior-Baie-019.jpg"
$pattern = "#^(.*/Baie)/.*$#";
preg_match($pattern,$path, $matchx);
echo $match[1];
?>

Answer 8

如果您想要第一次使用：

$path = "/home/design/Baie/Design-Interior-Baie-019.jpg";
$find = "Baie";

$pos = strpos($path,$find);

$newstr = substr($path, 0, $pos + strlen($find));

echo $newstr;
