What are common challenges when splitting SQL statements in a string using PHP?

When splitting SQL statements in a string using PHP, a common challenge is handling cases where the SQL statement contains special characters or multiple statements. To solve this, you can use a regular expression to split the SQL string based on common delimiters like semicolons while considering special cases like single quotes within the SQL statements. 

$sql = "SELECT * FROM table1; INSERT INTO table2 VALUES ('value1', 'value2');";
$statements = preg_split('/;(?=(?:[^\']*\'[^\']*\')*[^\']*$)/', $sql);

foreach ($statements as $statement) {
    // Execute each SQL statement
    echo $statement . "\n";
}
