Splits the source string into an array of strings, using a delimiter.
This plugin creates an array of strings by splitting the source parameter on boundaries formed by the delimiter.
Available configuration keys:
- source: The source string.
- limit: (optional)
- If limit is set and positive, the returned array will contain a maximum of limit elements with the last element containing the rest of string.
- If limit is set and negative, all components except the last -limit are returned.
- If the limit parameter is zero, then this is treated as 1.
- delimiter: The boundary string.
- strict: (optional) When this boolean is TRUE, the source should be strictly a string. If FALSE is passed, the source value is casted to a string before being split. Also, in this case, the values casting to empty strings are converted to empty arrays, instead of an array with a single empty string item ['']. Defaults to TRUE.
Example:
process:
bar:
plugin: explode
source: foo
delimiter: /
If foo is "node/1", then bar will be ['node', '1']. The PHP equivalent of this would be:
$bar = explode('/', $foo);
process:
bar:
plugin: explode
source: foo
limit: 1
delimiter: /
If foo is "node/1/edit", then bar will be ['node', '1/edit']. The PHP equivalent of this would be:
$bar = explode('/', $foo, 1);
If the 'strict' configuration is set to FALSE, the input value is casted to a string before being spilt:
process:
bar:
plugin: explode
source: foo
delimiter: /
strict: false
If foo is 123 (as integer), then bar will be ['123']. If foo is TRUE, then bar will be ['1']. The PHP equivalent of this would be:
$bar = explode('/', (string) 123);
$bar = explode('/', (string) TRUE);
If the 'strict' configuration is set to FALSE, the source value casting to an empty string are converted to an empty array. For example, with the last configuration, if foo is '', NULL or FALSE, then bar will be [].
