Remove Element From Array PHP

In this tutorial we will show you the solution of remove element from array PHP, as we know array will had more than two many values here we using array_splice() method for removing last element from we defined array.

The array_splice() function removes selected elements from an array and replaced it with new elements.

This function also returns an array with the removed elements.

Step By Step Guide On Remove Element From Array PHP :-

Here we defined an array namely ‘$names’ with some initialized values 'KTM','RAY-ZR','RE','JAWA'.

For user clarification we first printed our array elements by print_r() method with headlines then we using array_splice() method.

In array_splice method we are going to pass three parameters, first parameter will be our array_name, second parameter is starting point of want to remove element position, final parameter refers count(length) of elements.

Here we removed only one element from 1st position of one element in array $names then we printed.

<?php
    $names=array('KTM','RAY-ZR','RE','JAWA');
    echo "Removing Element From Array<br>";
    echo"<br>";
    echo "Before using array_splice() method:<br>";
    print_r($names);
    echo"<br><br>";
    echo "After using array_splice() method:<br>";
    array_splice($names,1,1);
    print_r($names);
?>
  1. A php script can be placed anywhere in the document. A php script starts with <?php and end with ?>.
  2. The default file extension for php files is “.php” and php statements end with ‘;’ semicolon.
  3. Here we defined array $names with some string values 'KTM','RAY-ZR','RE','JAWA'. Then we printed headline of program for describe about program concept.
  4. Then we printed our array $names elements and for instruct users before using array_splice method how it will look.
  5. Then we applied array_splice() method with three parameters ($names,1,1). $names-refers array name, 1-refers starting point of removing element,1-length of elements in array.
  6. Here we passed element will points element position(index) 1 then length also 1 so (i.e) 'RAY-ZR' from array $names.
  7. After using array_splice() method we printed array $names for user can found we pointed element is removed from array.
  8. When we seeing our result we will know that is it will affect the original array and rearrange the elements within array for replacing removed element location (index).
  9. Then when printing array we must use print_r() method otherwise we get error on webpage.
  10. For removing element from array we had another method in php (i.e)unset() function so we will see this method in future.

Conclusion :-

In conclusion we are able to know how to remove element from array using php.

First we need to start our xampp server then we load this program on browser we can see headline about the program and before applying array_splice method we displayed array with values then we displayed after applied array_splice() result of array so user can easily understand when seeing result on webpage.

You can define array with some other values like array with numeric values and associative array elements anything result will same but be aware when printing result.

I hope this tutorial on remove element from array PHP helps you and the steps and method mentioned above are easy to follow and implement.
