As a web developer, you may need to display a collection of images from a folder on your website. PHP view images in folder method can be implemented in several ways. You can use various functions to show pictures on a web page. This article will discuss four different methods to display images from a folder using PHP. You will learn about the other functions, advantages, and limitations.
You can find ready-to-test PHP codes below, copy and test them to see how codes show images from a directory.
The glob() function is a simple way to view images in the folder and retrieve files of a specific type from a directory. You can retrieve images with specific extensions such as .jpg, .png, .gif, etc. After you retrieve the file names, you can loop through them to print. Then use the echo img src method to display the images on the webpage.
Here is the code example for using glob():
The scandir() function is another method to retrieve files from a directory. Unlike glob(), scandir() returns all the files in a directory. You will need to filter out the non-image files using the in_array() function. You can then use the same echo img src method to display the images.
Here is the code example for using scandir():
The DirectoryIterator() function is an object-oriented way of retrieving files from a directory. You can use the isFile() method to check if a file is an image and then display it using the same echo img src method.
Here is the code example for using DirectoryIterator():
The RecursiveDirectoryIterator() function is similar to the DirectoryIterator() function but can also recursively search through subdirectories. This is useful if you have multiple levels of subdirectories containing images. You can use the same isFile() and echo img src method as with the DirectoryIterator().
Here is the code example for using RecursiveDirectoryIterator():
Before We End
To implement “PHP view images in folder” you can choose the method that best suits your needs. The glob() and scandir() functions are the simplest, but they may need to work more efficiently with large numbers of files. The DirectoryIterator() and RecursiveDirectoryIterator() functions offer more flexibility and can handle larger file sets.
However, it is important to remember that using these functions can pose security risks if not implemented correctly. You should always validate the input and filter out non-image files to prevent malicious code from executing.
When using these functions, test your code and ensure that it works correctly for all image extensions you want to display. You can also use these functions to create image galleries or to display images dynamically based on user input.
