Converting an integer to a string in PHP
有没有办法将整数转换为PHP中的字符串？
You can use the strval() function to convert a number to a string.
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
// Explicit cast
$items = (string)$var; // $items === "5";
// Function call
$items = strval($var); // $items === "5";
There's many ways to do this.
Two examples:
$str = (string) $int;
$str = "$int";
See the PHP Manual on Types Juggling for more.
$foo = 5;
$foo = $foo . "";
now $foo is a string.
But, you may want to get used to casting. As casting is the proper way to accomplish something of that sort.
$foo = 5;
$foo = (string)$foo;
Another way is to encapsulate in quotes:
$foo = 5;
$foo = "$foo"
