Why does this record produce a fatal error?

Question

PHP

Why does this record produce a fatal error? Meanwhile, so true:
$text = str_replace("[id", "[", $text, 1);

$count = 1;
$text = str_replace("[id", "[", $text, $count);

Tell me what to do, I do not want to create a separate variable for this argument.

Answer 1

Because $count is not a limit on the number of replacements, but it records how many times the replacement worked.
Therefore, it is necessary to pass a variable there, not a number.

str_replace(
    array|string $search,
    array|string $replace,
    string|array $subject,
    int &$count = null
): string|array
