PHP filter_var_array()Functions
Complete PHP Filter Reference Manual
Definition and Usage
The filter_var_array() function gets multiple variables and filters them.
This function is useful for filtering multiple values, without needing to call filter_var() repeatedly.
If successful, it returns the values of the requested variables as an array. If it fails, it returns FALSE.
Syntax
filter_var_array(array, args)
| Parameters | Description |
|---|---|
| array | Required. Specifies an array with string keys, containing the data to be filtered. |
| args | Optional. Specifies an array of filter parameters. Valid array key names are variable names, and valid values are filter IDs, or an array specifying the filter, flags, and options. This parameter can also be a single filter ID. If so, all values in the input array are filtered by the specified filter. The filter ID can be an ID name (such as FILTER_VALIDATE_EMAIL) or an ID number (such as 274). |
