PHP array_push() Function

array_push() in PHP is used to append the given values to the array. Simply, it will add values to the end of the input array. At a time, it is possible to append multiple values to an array.

Syntax:
array_push(array_input,value,………..)

Parameters:

1. array_input is the array.
2. Value/s will be added to the array at the end.

Let’s see examples to understand this concept better.

Example 1:
In this example, we will create an array with 4 values: ‘lotus’,’lilly’,’jasmine’,’rose’.
Now, we will add the value ‘marigold’ to the array.

Output:

We can see that marigold has been added to the Flower array.

Example 2:
In this example, we will create an array with four values: ‘lotus’,’lilly’,’jasmine’,’rose’.
Now, we will add three values-‘marigold’,’rose’,’lotus’ to the array.

Output:

We can see that ‘marigold’,’rose’,’lotus’ have been added to the Flower array. If you want to add values to the key-value pair array, then the values will also get the keys with numeric values.

Example 3:
In this example, we will create an array with four key-values: ‘flower1’=>’lotus’,’flower2’=>’lilly’,’flower3’=>’jasmine’,’flower4’=>’rose’.
Now, we will add 3values-‘marigold’,’rose’,’lotus’ to the array.

Output:

We can see that ‘marigold’,’rose’,’lotus’ have been added to the Flower array with keys-0,1 and 2.

Example 4:
In this example, we will create an array with four key-values: 1=>’lotus’,2=>’lilly’,3=>’jasmine’,4=>’rose’.
Now we will add 3 values-‘marigold’,’rose’,’lotus’ to the array.

Output:

We can see that ‘marigold’,’rose’,’lotus’ have been added to the Flower array with keys-5,6 and 7.

Conclusion

In this article, we saw how to append elements to the PHP array using the array_push() function.

It is possible to add single or multiple elements to the array at a time. We have to notice that if we add values to the key value pair array, then the newly added elements will be assigned keys of numeric type.
