multiple string replace in php

Question

php

$nn="ab bc cd cd ab";
$tttt=str_ireplace("cd","aaa",$nn);
$tt=str_ireplace("ab","aaa",$tttt);

but the below coding is not working

$nn="ab bc cd cd ab";
$tttt=str_ireplace("cd" or "ab","aaa",$nn);

The output is "aaa bc aaa aaa aaa".PLease help me in simplyfying it.because there are lot more str replaces for various words.

You have a question in PHP about the function str_ireplace, so why don't you simply look into the manual? -> php.net/manual/en/function.str-ireplace.php <- Answer is there — Rizier123

Is this some kind of homework/school project? Other user: stackoverflow.com/q/31895327/3933332 but very similar coding style, variable names and writing style. — Rizier123

You use array in first parameter of str_ireplace.

$nn="ab bc cd cd ab";
$replace_words = array("ab", "cd");
$tttt = str_ireplace($replace_words, "aaa", $nn);

You may use preg_replace which accepts regex as the first argument. ab|cd would match ab or cd.

preg_replace('~cd|ab~i', 'aaa', $nn);

And add i modifier for doing case-insensitive match.

No need for a regex here, since the function also takes an array as argument. (But it would work too :)

Even the manual agrees with me: If you don't need fancy replacing rules, you should generally use this function instead of preg_replace() with the i modifier. :]
