What are some common methods in PHP to separate variables from a string with a specific delimiter?

When dealing with strings that contain multiple variables separated by a specific delimiter, common methods in PHP to separate these variables include using functions like explode() or preg_split(). These functions allow you to split the string based on the delimiter and store the separated variables in an array for further processing.

// Example using explode() function to separate variables from a string with a specific delimiter
$string = "apple,banana,orange";
$delimiter = ",";
$variables = explode($delimiter, $string);

// Output the separated variables
foreach ($variables as $variable) {
    echo $variable . "\n";
}
