PHP library which provides string interpolation (variable expansion) functionality

Install
-------

[](#install)

```
composer require visual-craft/string-interpolator
```

Usage
-----

[](#usage)

#### Instantiate interpolator object

[](#instantiate-interpolator-object)

```
use VisualCraft\StringInterpolator\StringInterpolator;

$interpolator = new StringInterpolator();
```

#### String interpolation

[](#string-interpolation)

```
$result = $interpolator->interpolate('Demonstration $var1 $var2.', [
    'var1' => 'of',
    'var2' => 'interpolation',
]);
// $result === "Demonstration of interpolation."
```

Variable name can be enclosed with '{' and '}' to separate from the rest of the string:

```
$result = $interpolator->interpolate('test${var1}test', [
    'var1' => '123',
]);
// $result === "test123test"
```

'$var\_name' can be escaped with '\\':

```
$result = $interpolator->interpolate('$var1 \$var2', [
    'var1' => '123',
]);
// $result === "123 $var2"
```

`VisualCraft\StringInterpolator\MissingVariableException` will be thrown if variable is missing:

```
$result = $interpolator->interpolate('$var1 $var2', [
    'var1' => '123',
]);
// PHP Fatal error:  Uncaught VisualCraft\StringInterpolator\MissingVariableException: Missing variable 'var2'
```

#### Get variables names from subject

[](#get-variables-names-from-subject)

```
$result = $interpolator->getVariablesNames('Demonstration $var1 $var2.');
// $result === ['var1', 'var2']
```

#### Get variables counts from subject

[](#get-variables-counts-from-subject)

```
$result = $interpolator->getVariablesCounts('Demonstration $var1 $var2. $var1');
// $result === ['var1' => 2, 'var2' => 1]
```
