# $indexOf

Returns the character index of a 'query' within 'text'.

### Usage

```php
$indexOf[text;query]
```

This function has two params.

| Param | Description                                 | Type   | Required |
| ----- | ------------------------------------------- | ------ | -------- |
| text  | The text that gets searched for 'query'.    | String | Yes      |
| query | The phrase/character to find within 'text'. | String | Yes      |

{% hint style="danger" %}
Remember the case of characters in \`$indexOf\[]\` matters (e.g. searching for a lowercase \`h\` within \`Hello\` won't work). You can use \[\`$toLowerCase\[]\`]\(./tolowercase.md) to negate this issue.
{% endhint %}
