Full Concepts On array_keys() Function With 3 Coding Examples Prepared By Me Of Array Functions In PHP Q1. What is meant by array_keys()? Ans: array_keys() returns an array containing the keys. Coding Example : 01 => <?php $arrayName = array ( 'name' => 'Ayan' , 'age' => '28' , 'gender' => 'male' ); $arrkeys = array_keys ( $arrayName ); print_r ( $arrkeys ); ? > Output Of The Coding Example : 01 => Coding Example : 02 => <?php $arrayName = array ( 'Company Name' => 'Capgemini' , 'Established Year' => '1967' ); $arrkeys = array_keys ( $arrayName ); print_r ( $arrkeys ); ? > Output Of The Coding Example : 02 => Coding Example : 03 => <?php $arrayName = array ( 'Name of the cricketer' => 'M.S.Dhoni' , 'Team' => 'India' ); $arrkeys = array_keys ( $arrayName ); print_r ( $arrkeys ); ? > Output Of The Coding Example : ...

Full Concepts On array_reverse() Function Along With A Coding Example Prepared By Me Of Array Functions In PHP Q1. Why the array elements are not reversed while using "array_reverse($arr);"? Ans: The array elements are not reversed while using array_reverse($arr) because after manipulation it's not able to store anywhere, but the array_reverse() function is working. Q2. Why in other functions manipulation is working and output is generated while in "array_reverse($arr)" manipulation is not working and output is not reversed? Ans: In other functions manipulation is working and output is generated while in "array_reverse($arr)" manipulation is not working and output is not reversed because in other functions we are either adding or deleting the array elements where in adding the array elements it is fixed while in deleting the array elements we are terminating the array elements , so there is nothing to store after manipulation, but in array_reverse() fu...

Full Concepts On array_shift() And array_unshift() Function With 3 Coding Examples Each Prepared By Me Of Array Functions In PHP Q1. What is meant by array_shift()? Ans: array_shift() removes the first element of an array. Coding Example : 01 => <?php $arr =[ "Dog" , "Cat" , "Tiger" ]; $arrshift = array_shift ( $arr ); print_r ( $arr ); ? > Output Of Coding Example : 01 => Coding Example : 02 => <?php $arr =[ "3" , "4" , "8" , "16" ]; $arrshift = array_shift ( $arr ); print_r ( $arr ); ? >   Output Of Coding Example : 02 => Coding Example : 03 => <?php $arr =[ "Ginny" , "Abhishek" , "Rohaan" ]; $arrshift = array_shift ( $arr ); print_r ( $arr ); ? > Output Of Coding Example : 03 => Q2. What is meant by array_unshift()? Ans: array_unshift() function inserts elements at the beginning of an array. Coding Example : 01 => <?php $arr =[ "1" ,...
