What are some strategies for efficiently extracting data using preg_match_all in PHP?

When using preg_match_all in PHP to extract data from a string, it is important to efficiently capture the desired information without unnecessary overhead. One strategy is to use specific regex patterns to target the exact data you need, rather than using broad patterns that may capture more than necessary. Additionally, utilizing capturing groups in the regex pattern can help isolate and extract specific parts of the data. 

// Example code snippet for efficiently extracting data using preg_match_all

// Sample string containing data to extract
$data = "Name: John Doe, Age: 30, Occupation: Developer";

// Define a regex pattern to capture the desired data (e.g., name, age, occupation)
$pattern = '/Name: (.*?), Age: (.*?), Occupation: (.*?)/';

// Perform preg_match_all to extract the data using the defined pattern
preg_match_all($pattern, $data, $matches, PREG_SET_ORDER);

// Output the extracted data
foreach ($matches as $match) {
    $name = $match[1];
    $age = $match[2];
    $occupation = $match[3];

    echo "Name: $name, Age: $age, Occupation: $occupation";
}
