How to Convert Integer to String in PHP ?

Answer

In PHP, you can convert an integer to a string using type casting or concatenation.

✐ Examples

1 Convert Integer to String using Type Casting

In this example,

We declare an integer variable named $num and assign it a value of 42.
We then use type casting to convert the integer $num to a string by enclosing it in quotes and store the result in the variable $strNum.
The type casting operation converts the integer to its string representation.
Finally, we echo the string representation of the integer.

PHP Program

<?php 
// Convert Integer to String using Type Casting
$num = 42;
$strNum = (string)$num;
echo "String representation of integer: $strNum";
?>

Output

String representation of integer: 42

2 Convert Negative Integer to String using Concatenation

In this example,

We declare a negative integer variable named $negativeNum with a value of -10.
We then concatenate the negative integer $negativeNum with an empty string and store the result in the variable $strNegativeNum.
The concatenation operation converts the integer to its string representation.
Finally, we echo the string representation of the negative integer.

PHP Program

<?php 
// Convert Negative Integer to String using Concatenation
$negativeNum = -10;
$strNegativeNum = $negativeNum . '';
echo "String representation of negative integer: $strNegativeNum";
?>

Output

String representation of negative integer: -10
