PHP Time Limits Configuration

what is max_input_time and execution time
1. **`max_input_time`**:
– This setting determines how much time (in seconds) PHP will spend parsing input data, such as POST, GET, and file uploads.
– Default value: `60` seconds.
– Recommended value for high-resource tasks: `300` or higher (depending on your application needs).
2. **`max_execution_time`**:
– This setting limits the maximum amount of time (in seconds) that a PHP script is allowed to run before it is terminated.
– Default value: `30` seconds.
– Recommended value: Increase it to `300` or higher for resource-intensive processes like imports, exports, or bulk operations.
### Suggested Configuration for Your Case
Given that you have a **memory limit of 1000M** and **max input vars of 10000**, it indicates a high-resource application. You might set:
– **`max_input_time`**: `300`
– **`max_execution_time`**: `300` or more (adjust based on the longest-running scripts you anticipate)
### How to Set These
1. **In `php.ini`**:
max_input_time = 300
max_execution_time = 300
2. **Using `.htaccess`** (if PHP is running as an Apache module):
php_value max_input_time 300
php_value max_execution_time 300
3. **In a script (as a last resort)**:
ini_set('max_input_time', 300);
ini_set('max_execution_time', 300);
Ensure to restart your web server or PHP process (e.g., `php-fpm`) after modifying the settings.
### Key Points About `max_input_time`:
– **Purpose**: It governs the time PHP spends parsing input data (e.g., form submissions, file uploads, query strings).
– **Impact**:
– A higher value ensures large or complex inputs have enough time to be processed without prematurely timing out.
– It does **not** affect how quickly your server responds to regular requests.
### When Higher `max_input_time` Is Needed:
You only need a high `max_input_time` if:
1. You handle **large file uploads**.
2. Your application processes **very large POST requests** (e.g., from forms with a high number of fields or large JSON data).
3. You have **long-running input-parsing operations**.
### Does It Slow the Site?
– For most page loads, this setting isn’t a factor because input parsing completes quickly.
– If input parsing does take a long time (due to large data), the **specific request** may take longer, but increasing `max_input_time` ensures it completes instead of failing.
### Recommendations:
1. **Default Setting**: Keep it at `60` unless you encounter issues with input size or processing.
2. **Custom Needs**: Use `300` only if your application requires handling larger data input.
3. **Performance Consideration**: If your site feels slow, look at broader performance factors (like database queries, PHP execution, caching) rather than this setting.
In summary, a higher `max_input_time` won't slow down your site unless you're constantly handling large or complex inputs, which might suggest other areas to optimize.
