If a string ends with the character X
, i want to replace that particul开发者_开发百科ar character with the character Y
.
Example 1
anything_number_alphabet_dashes_anythingX[END OF STRING]
to
anything_number_alphabet_dashes_anythingY[END OF STRING]
Example 2
DontReplaceThis_X_JustOnlyThisLast_X[END OF STRING]
to
DontReplaceThis_X_JustOnlyThisLast_Y[END OF STRING]
I want to do this in PHP with preg_replace
or ereg_replace
.
Dollar sign is the end of string anchor, so:
$new_str = preg_replace('/X$/', 'Y', $old_str);
