When encountering a blank page issue after exporting a CSV file in PHP there are a few potential causes and troubleshooting steps to consider: Error Reporting : Check if error reporting is enabled in your PHP configuration. If not enable it to see if any error messages are displayed on the blank page. This can provide valuable information about the issue. Memory Limit : Exporting large datasets to a CSV file can consume a significant amount of memory. Check if the memory limit in your PHP configuration is sufficient for the operation. You can increase the memory limit by modifying the memory_limit directive in your php.ini file or using the ini_set() function in your PHP script. Execution Time : Exporting a large amount of data to a CSV file can also take a considerable amount of time. Check if the execution time limit in your PHP configuration is adequate. You can increase the execution time limit by modifying the max_execution_time directive in your php.ini file or using the set_time_limit() function in your PHP script. Script Errors : Review your PHP script that handles the export functionality for any syntax errors or logical issues that may cause the blank page. Ensure that all necessary variables are properly initialized and that error handling is implemented to catch any exceptions or errors that may occur during the export process. Debugging : Implement debugging techniques such as logging or using var_dump() or print_r() statements to track the flow of your script and identify any potential issues or unexpected behavior. By following these troubleshooting steps you should be able to identify and resolve the blank page issue after exporting a CSV file in PHP.
