How can PHP functions like explode() and substr() be effectively utilized for extracting specific data from a text file in PHP?
When extracting specific data from a text file in PHP, functions like explode() can be used to split the text into an array based on a specified delimiter, while substr() can be used to extract a portion of the text based on the starting position and length. By combining these functions, you can effectively extract the desired data from the text file.
// Read the contents of the text file
$file_contents = file_get_contents('data.txt');
// Use explode() to split the text into an array based on a delimiter
$data_array = explode(',', $file_contents);
// Use substr() to extract specific data from the array
$specific_data = substr($data_array[0], 0, 5);
// Output the extracted data
echo $specific_data;
