Parameter-Liste

needle

The string to find in haystack.

offset
May be specified to begin searching an arbitrary number of characters into the string. Negative values will stop searching at an arbitrary point prior to the end of the string.

Der encoding Parameter legt das Zeichenencoding fest. Wird er nicht übergeben so wird die interne Zeichenkodierung genutzt.

Anmerkungen

Hinweis: The encoding parameter was moved from the third position to the fourth in PHP 5.2.0. For backward compatibility, encoding can be specified as the third parameter, but doing so is deprecated and will be removed in the future.
