Question

我想从路径中删除其他反斜杠（\）。

我有这段代码。

$imagePath='/images/';
$query=mysqli_query($conn,"select sid,fname,mname,lname,did,ppic from hrm_staff ");

if(mysqli_num_rows($query) >0) {
 $response["hrm_staff"] = array();


while ($row = mysqli_fetch_array($query)) {

     $recp = array();
     $recp["sid"]=$row["sid"];
     $fullName=$row['fname']."".$row['mname']."".$row['lname'];

     $recp["fname"]= $fullName;
     $recp["did"]=$row['did'];

     $ppic=$row['ppic'];

     $ppic=$imagePath.$ppic;
     $ppic = str_replace('\\','',$ppic);

     $recp["ppic"]= $ppic;

     array_push($response["hrm_staff"], $recp);
}

 echo json_encode($response);

当我print或echo时，我会收到此输出。

{"hrm_staff":[
    {"sid":"1","fname":"GaneshMB","did":"6","ppic":"\/images\/ prof_pic\/sb.jpg"},
    {"sid":"2","fname":"SwatiK","did":"5","ppic":"\/images\/ prof_pic\/ulogo.png"},
    {"sid":"3","fname":"KomalC","did":"2","ppic":"\/images\/ prof_pic\/p1.jpg"},
    {"sid":"4","fname":"KarthikR","did":"2","ppic":"\/images\/ prof_pic\/p3.jpg"},
    {"sid":"5","fname":"RenuP","did":"5","ppic":"\/images\/ prof_pic\/p6.jpg"},
    {"sid":"6","fname":"RahulMA","did":"5","ppic":"\/images\/ prof_pic\/p4.jpg"}
 ],"success":1,"message":"display records"}

即使使用str_replace()后，我在图像路径中也会收到额外的反斜杠（\）。我无法找到我犯错误的地方。

请帮帮我。

Answer 1

在json格式上使用json_decode()。这应该可以解决问题。

$a = '{"hrm_staff":[
{"sid":"1","fname":"GaneshMB","did":"6","ppic":"\/images\/     prof_pic\/sb.jpg"},
{"sid":"2","fname":"SwatiK","did":"5","ppic":"\/images\/ prof_pic\/ulogo.png"},
{"sid":"3","fname":"KomalC","did":"2","ppic":"\/images\/ prof_pic\/p1.jpg"},
{"sid":"4","fname":"KarthikR","did":"2","ppic":"\/images\/ prof_pic\/p3.jpg"},
{"sid":"5","fname":"RenuP","did":"5","ppic":"\/images\/ prof_pic\/p6.jpg"},
{"sid":"6","fname":"RahulMA","did":"5","ppic":"\/images\/ prof_pic\/p4.jpg"}
],"success":1,"message":"display records"}';


Print_r(json_decode($a));

Answer 2

我得到了答案。 trim（$ variable） 为我完成了这项工作。

这就是我所做的和它的工作。

$imagePath='www.abc.com/hrm';
$ppic1=$row['ppic'];
$ppic21=$imagePath."/".trim($ppic1); // here trim($ppic1) removed that extra character (\) from the url.

如何使用PHP从url字符串中删除反斜杠？
