How can PHP developers ensure that numeric data is treated as text when exporting to Excel?

When exporting numeric data to Excel using PHP, developers can ensure that the data is treated as text by prefixing it with an apostrophe ('). This forces Excel to interpret the data as text, preventing any automatic formatting or conversion to numbers. By adding this simple character before the numeric data, developers can maintain the original format and avoid any unintended changes. 

// Numeric data to export to Excel
$numericData = 12345;

// Prefix the numeric data with an apostrophe to treat it as text
$textData = "'" . $numericData;

// Output the data to Excel
echo $textData;
