password_verify — Verifies that a password matches a hash

Description

password_verify(string $password, string $hash): bool

Note that password_hash() returns the algorithm, cost and salt as part of the returned hash. Therefore, all information that's needed to verify the hash is included in it. This allows the verify function to verify the hash without needing separate storage for the salt or algorithm information.

This function is safe against timing attacks.

Parameters

The user's password.

A hash created by password_hash().

Return Values

Returns true if the password and hash match, or false otherwise.

Examples

$hash = '$2y$07$BCryptRequires22Chrcte/VlQH0piJtjXl.0t1XkA8pw9dMXTpOq';

How To Create a Login Form

Step 1) Add HTML:

Add an image inside a container and add inputs (with a matching label) for each field. Wrap a

element around them to process the input. You can learn more about how to process input in our PHP tutorial.

Example

 

   

 

 

    Username
   

    Password
   

    Login
   
      Remember me
   
 

 

    Cancel
    Forgot password?
 

Step 2) Add CSS:

Example

/* Bordered form */
form {
  border: 3px solid #f1f1f1;
}

/* Full-width inputs */
input[type=text], input[type=password] {
  width: 100%;
  padding: 12px 20px;
  margin: 8px 0;
  display: inline-block;
  border: 1px solid #ccc;
  box-sizing: border-box;
}

/* Set a style for all buttons */
button {
  background-color: #04AA6D;
  color: white;
  padding: 14px 20px;
  margin: 8px 0;
  border: none;
  cursor: pointer;
  width: 100%;
}

/* Add a hover effect for buttons */
button:hover {
  opacity: 0.8;
}

/* Extra style for the cancel button (red) */
.cancelbtn {
  width: auto;
  padding: 10px 18px;
  background-color: #f44336;
}

/* Center the avatar image inside this container */
.imgcontainer {
  text-align: center;
  margin: 24px 0 12px 0;
}

/* Avatar image */
img.avatar {
  width: 40%;
  border-radius: 50%;
}

/* Add padding to containers */
.container {
  padding: 16px;
}

/* The "Forgot password" text */
span.psw {
  float: right;
  padding-top: 16px;
}

/* Change styles for span and cancel button on extra small screens */
@media screen and (max-width: 300px) {
  span.psw {
    display: block;
    float: none;
  }
  .cancelbtn {
    width: 100%;
  }
}

How To Create a Modal Login Form

      Password
     

      Login
     
        Remember me
     
   

   

      Cancel
      Forgot password?
   

 

Step 2) Add CSS:

Example

/* The Modal (background) */
.modal {
  display: none; /* Hidden by default */
  position: fixed; /* Stay in place */
  z-index: 1; /* Sit on top */
  left: 0;
  top: 0;
  width: 100%; /* Full width */
  height: 100%; /* Full height */
  overflow: auto; /* Enable scroll if needed */
  background-color: rgb(0,0,0); /* Fallback color */
  background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
  padding-top: 60px;
}

/* Modal Content/Box */
.modal-content {
  background-color: #fefefe;
  margin: 5px auto; /* 15% from the top and centered */
  border: 1px solid #888;
  width: 80%; /* Could be more or less, depending on screen size */
}

/* The Close Button */
.close {
  /* Position it in the top right corner outside of the modal */
  position: absolute;
  right: 25px;
  top: 0;
  color: #000;
  font-size: 35px;
  font-weight: bold;
}

/* Close button on hover */
.close:hover,
.close:focus {
  color: red;
  cursor: pointer;
}

/* Add Zoom Animation */
.animate {
  -webkit-animation: animatezoom 0.6s;
  animation: animatezoom 0.6s
}

@-webkit-keyframes animatezoom {
  from {-webkit-transform: scale(0)}
  to {-webkit-transform: scale(1)}
}

@keyframes animatezoom {
  from {transform: scale(0)}
  to {transform: scale(1)}
}

Tip: You can also use the following javascript to close the modal by clicking outside of the modal content (and not just by using the "x" or "cancel" button to close it):
