How Can I Properly Explode a PHP String by Newline Characters?

Explode PHP String by New Line

Question:

When attempting to explode a PHP string by newline characters using the code below, the operation fails:

$skuList = explode('\n\r', $_POST['skuList']);

Solution:

The correct approach to explode a PHP string by newline is to use the PHP constant PHP_EOL, which represents the current system's end of line (EOL) character.

$skuList = explode(PHP_EOL, $_POST['skuList']);

Additional Considerations:

• Ensure that PHP_EOL is used for all EOL-related tasks to maintain code system independence.
• Data stored with system-dependent EOL characters should be parsed before storage to prevent compatibility issues when moving between systems.

Expanded Solution:

For cases where the origin of the newline characters is unknown or may vary, a more comprehensive solution is recommended:

$skuList = preg_split('/\r\n|\r|\n/', $_POST['skuList']);

This regular expression pattern matches all common newline characters and ensures that the string is exploded correctly regardless of the operating system's EOL conventions.
