strrchr() – PHP String Functions

by · Published · Updated

Syntax :

string strrchr ( string, char_string );

Description :

strrchr() function will find the last occurrence of char_string in a string and returns all characters from this position to the end of the string.

Note : case sensitive and binary-safe function.

Parameter :

  • string – This is a Required parameter. This is the string in which search will take place.
  • char_string – This is a Required parameter. It contains the value to be searched. If we pass this parameter as a number, then it will search for the character matching the ASCII value of the number.  This behavior is deprecated as of PHP 7.3.0, and relying on it is highly discouraged. Depending on the intended behavior, the char_string should either be explicitly cast to string, or an explicit call to chr() should be performed.

Output :

It will returns below values:

  • the portion of string after the last occurrence is found in the string.
  • FALSE if the search is not found in the string.
