Fgetss()

What is the fgetss() Function?

The fgetss() function is a built-in PHP function that reads a line from a file and removes any HTML or PHP tags from the line. This function is similar to the fgets() function, but it also removes any tags from the line that it reads.

Here's the basic syntax of the fgetss() function:

fgetss(file, length, allowable_tags);

Where file is the file pointer, length is the maximum length of the line to be read, and allowable_tags is a string containing a list of tags that should not be stripped from the line. If the allowable_tags parameter is not specified, all HTML and PHP tags will be stripped from the line.

How to Use the fgetss() Function?

Using the fgetss() function is similar to using the fgets() function. Here are the steps to follow:

1. Open the file using the fopen() function.
2. Use the fgetss() function to read a line from the file and remove any tags.
3. Close the file using the fclose() function.

Here's an example code snippet that demonstrates how to use the fgetss() function to read a file line by line:

<?php

$file = fopen("file.txt", "r");

// Read the first line from the file
$line = fgetss($file);

// Loop through the file until the end is reached
while (!feof($file)) {
    // Process the line
    echo $line;

    // Read the next line
    $line = fgetss($file);
}

// Close the file
fclose($file);

In this example, we first open a file named file.txt using the fopen() function. Then we read the first line from the file using the fgetss() function and store it in the $line variable. We then loop through the file until the end is reached using the feof() function. Inside the loop, we process the line and print it to the screen using the echo statement. Finally, we read the next line from the file using the fgetss() function and store it in the $line variable. Once we reach the end of the file, we close the file using the fclose() function.

Conclusion

The fgetss() function is a useful tool in PHP for reading text files while also removing any HTML or PHP tags from the file. By following the steps outlined in this guide, you can easily use the fgetss() function in your PHP projects to read files line by line while also removing tags.
