Converting an integer to a string in PHP

Question 1

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

Question 2

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";

Question 3

It depends on the driver used between php and mysql.

Check which one of them is used by checking pdo_mysql section of the output of

php -i

your output should be similar to

pdo_mysql

PDO Driver for MySQL => enabled
Client API version => mysqlnd 5.0.12-dev - 20150407 - $Id: b396954eeb2d1d9ed7902b8bae237b287f21ad9e $

The native driver return integers as integers, but the other return them as strings.

So the solution is to remove the old driver and install the native one.

or to use $casts into your model.

    protected $casts = [
    'status' => 'integer',
];

Question 4

CStr(45) is all you need (the Convert String function)

Question 5

This is either a bug in TypeScript or a concious design decision, but you can work around it using:

var myBool: bool = true;
var myString: string = String(myBool);
alert(myString);

In JavaScript booleans override the toString method, which is available on any Object (pretty much everything in JavaScript inherits from Object), so...

var myString: string = myBool.toString();

... should probably be valid.

There is also another work around for this, but I personally find it a bit nasty:

var myBool: bool = true;
var myString: string = <string><any> myBool;
alert(myString);

Question 6

After analyzing your riddle, I think this is what you want:

$one = $_REQUEST["term"] . "%";

This appends the % sql placeholder to that search term. (That's what I surmise here.)
