Function __global->cms_empty_safe
Definitions
sources/global2.php
- Determine whether a variable is empty (empty being defined differently for different types).The string '0' is NOT considered empty, unlike the default PHP empty language construct.Generally this function is used if you don't want to check for array index presence, non-nullness, and non-blank-stringness via individual ANDd clauses.As this is a function and not a language construct, reference to non-set variables or array indices need guarding using @.
- Visibility: public
- Is abstract?: No
- Is static?: No
- Is final?: No
- Returns: bool
Parameters
| Name | Type | Passed by reference? | Variadic? | Default | Set | Range | Description |
|---|---|---|---|---|---|---|---|
| $var | mixed | No | No | required parameter | N/A | N/A | Input |
Returns
- Whether it is CONSIDERED empty
- Type: boolean
- Set: N/A
- Range: N/A
