Converting an integer to a string in PHP

Question

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

Answer 1

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  // 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";
