有没有办法在 PHP 中将整数转换为字符串?

Is there a way to convert an integer to a string in PHP?

推荐答案

您可以使用 strval() 函数将数字转换为字符串.

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

从维护的角度来看,您想要做的事情很明显,而不是其他一些更深奥的答案.当然,这取决于您的上下文.

From a maintenance perspective its obvious what you are trying to do rather than some of the other more esoteric answers. Of course, it depends on your context.

$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

// The two examples above have the same end value...
// ... And so do the two below

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

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