In PHP, you can use type conversion to convert an integer (int type) to a string (string type). There are several ways to achieve this conversion:

1. Use the (string) or strval() function:

$intNumber = 123;
strNumber=(string)strNumber = (string)strNumber=(string)intNumber; // 或者 strNumber=strval(strNumber = strval(strNumber=strval(intNumber);

2. Use the sprintf() function:

$intNumber = 123;
strNumber=sprintf("strNumber = sprintf("%s", strNumber=sprintf("intNumber);

3 . Use string concatenation:

$intNumber = 123;
strNumber=′′.strNumber = ''.strNumber=′′.intNumber;

In the above example, we concatenate the integer $intNumber into an empty string to achieve integer to string conversion.

No matter which method is chosen, the integer will eventually be converted to the corresponding string type.
