indicate human-oriented text, as opposed to a machine format.
itext

int
: Integer
An
integer. You are alternatively permitted to pass a string of
digits instead, which will be cast to an integer using
(int)
.
float
: Float
A
floating point number. You are alternatively permitted to
pass a numeric string (as defined by
is_numeric()
),
which will be cast to a float using (float)
.
bool
: Boolean
A boolean.
You are alternatively permitted to pass an integer
0
or
1
(other integers are not permitted) or a string
"on"
, "true"
or "1"
for
true
, and "off"
, "false"
or
"0"
for false
.
lookup
: Lookup array
An array whose values are
true
, e.g. array('key'
=> true, 'key2' => true)
. You are alternatively permitted
to pass an array list of the keys array('key', 'key2')
or a comma-separated string of keys "key, key2"
. If
you pass an array list of values, ensure that your values are
strictly numerically indexed: array('key1', 2 =>
'key2')
will not do what you expect and emits a warning.
list
: Array list
An array which has consecutive integer indexes, e.g.
array('val1', 'val2')
. You are alternatively permitted
to pass a comma-separated string of keys "val1, val2"
.
If your array is not in this form, array_values
is run
on the array and a warning is emitted.
hash
: Associative array
An array which is a mapping of keys to values, e.g.
array('key1' => 'val1', 'key2' => 'val2')
. You are
alternatively permitted to pass a comma-separated string of
key-colon-value strings, e.g. "key1: val1, key2: val2"
.
mixed
: Mixed
An arbitrary PHP value of any type.
