Special Function array()
There is a special function array() to populate arrays. Non-existing arrays are created, dimensioned and populated, existing arrays are redimensioned and overwritten.
$a = array("cat", "dog"); echo $a[0]; $a = array("dog"); echo $a[0]; //cat, dog
Notes:
ยท
You can only pass literal strings as values, not variables. Values are separated by commas.
