Converting an integer to a string in PHP
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.
$var = 5;// Inline variable parsingecho "I'd like {$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";
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"
