array php examples Code Explanation :
- ($wikitechy) holds the values in a php array as array("welcome","wikitechy","Arrays").
- var_dump($wikitechy); this var_dump() function returns the data type and its values.
Now we need to print the first element of an array.
-
1. First, we pass variable($wikitechy) name with index value[0], that fetchs the first element corresponding to the index value. Output will be welcome.
2.Next pass variable($wikitechy) name with index value[1], that fetchs the second element corresponding to the index value. Output will be wikitechy.
3.Next pass variable($wikitechy) name with index value[2],that fetchs the third element corresponding to the index value. Output will be Arrays.
