where does the starts_with function come from ?

[xiaochong0302]

the following code is part of AbstractStr class

https://github.com/phalcon/cphalcon/blob/master/phalcon/Support/Helper/Str/AbstractStr.zep

/**
     * Check if a string starts with a given string
     *
     * @param string $haystack
     * @param string $needle
     * @param bool   $ignoreCase
     *
     * @return bool
     */
    protected function toStartsWith(
        string haystack,
        string needle,
        bool ignoreCase = true
    ) -> bool {
        var child, parent;

        if ("" === haystack) {
            return false;
        }

        if likely ignoreCase {
            let child  = mb_strtolower(needle),
                parent = mb_strtolower(haystack);
        } else {
            let child  = needle,
                parent = haystack;
        }

        return starts_with(parent, child);
    }

from php8.0, we can use str_starts_with function, but where does the starts_with function come from ?

For cphalcon starts_with and ends_with are methods that are internal to Zephir. With PHP 8.0+ as you mentioned there is a native method in PHP. We will change those accordingly as time goes by.
