You can use the strval() function to convert a number to a string.

(您可以使用strval()函数将数字转换为字符串。)

From a maintenance perspective its obvious what you are trying to do rather than some of the other more esoteric answers.

(从维护的角度来看，它显然是您正在尝试做的事情，而不是其他一些更深奥的答案。)

Of course, it depends on your context.

(当然，这取决于您的上下文。)

$var = 5;

// Inline variable parsing
echo "I'd like {$var} waffles"; // = "I'd like 5 waffles

// String concatenation 
echo "I'd like ".$var." waffles"; // I'd like 5 waffles

// Explicit cast 
$items = (string)$var; // $items === "5";

// Function call
$items = strval($var); // $items === "5";
