PHP的字符串标记生成器

Question

I have used the String Tokenizer in Java. I wish to know if there is similar functionality for PHP. I have a string and I want to extract individual words from it.

eg. If the string is -

Summer is doubtful #haiku #poetry #babel

I want to know if it contains the hashtag #haiku.

Answer 1

strpos, stripos, strstr, stristr are easy solutions.

strpos example:

$haikuIndex = strpos( $str, '#haiku' ); 
if( $haikuIndex !== FALSE ) {
   // "#haiku" exists
}

strstr example:

$haikuExists = strstr( $str, '#haiku' );

if( $haikuExists !== FALSE ) {
   // "#haiku" exists
}
