How to retrieve images from MySQL database
In the article, we will provide a direct code for retrieving images from the database through a select statement. To retrieve the image from the database, you need the path of the image folder where you have moved/saved the image when you uploaded it. Now the code is given below to retrieve the image:-
<?php global $image_path; $image_path ='image_upload/'; $query = "SELECT * FROM users WHERE id=2"; $sql=mysqli_query($GLOBALS['db'],$query); $row=mysqli_fetch_array($sql); ?> <img src="<?php echo $GLOBALS['image_path'].$row['profile_image'];?>" class="img-responsive">
global is used to get the value of that variable which is used with it at all over pages. You can put it in your functions file.
Retrieving images from the database plays an important role in certain conditions that are illustrated below:
a) When someone accidentally deleted the image from one location
b) Forgotten to save the image
c) When there is a requirement of using the particular image for some another purpose.
d) For maintaining security
For maintaining security, companies store the entire project images in a database linked with metadata image and apply various restriction controls to access particular image restricted to a different individual, which makes image retrieval more challenging.
