Examples
Setting binary safe encoding
// Ensure binary-safe encoding is used mbstring_binary_safe_encoding(); // Perform operations that require binary-safe encoding // ... // Reset encoding to the original setting reset_mbstring_encoding();
Working with binary data
// Set binary safe encoding
mbstring_binary_safe_encoding();
// Load binary data from a file
$binary_data = file_get_contents('example.bin');
// Perform operations on binary data
// ...
// Reset encoding back to the original setting
reset_mbstring_encoding();
Recursive calls
function perform_binary_operations() {
// Set binary safe encoding
mbstring_binary_safe_encoding();
// Perform operations that require binary-safe encoding
// ...
// Reset encoding to the original setting
reset_mbstring_encoding();
}
// Calling the function twice, each call sets and resets the encoding
perform_binary_operations();
perform_binary_operations();
Using with image manipulation
// Set binary safe encoding
mbstring_binary_safe_encoding();
// Load image data
$image_data = file_get_contents('example.jpg');
// Perform image manipulation operations
// ...
// Save manipulated image
file_put_contents('example_modified.jpg', $image_data);
// Reset encoding back to the original setting
reset_mbstring_encoding();
Binary-safe string operations
// Set binary safe encoding
mbstring_binary_safe_encoding();
// Binary data as a string
$binary_string = "example\x00binary\x00data";
// Get the length of the binary string
$length = strlen($binary_string);
// Reset encoding back to the original setting
reset_mbstring_encoding();
// Output: Length of the binary string is 19
echo "Length of the binary string is {$length}";
