preg_replace

[stubarny]

Hi everyone,

I'm writing a bit of code to delete "[[:<:]]" and "[[:>:]]" from strings in an array. Only I'm getting confused because the "[" and "]" symbols have special meaning that I can't figure out how to surpress. I tried putting forward slashes and backward slashes in front of the symbols but no luck.

If you could provide any pointers I'd be very grateful!

Thanks,

Stu

  $terms_db_no_word_boundaries[] = $term_db;
}

Escape it using using a backslash.

[code]<?php

foreach($terms_db as $term_db)
{
  $term_db = preg_replace("\[\[:<:\]\]", "", $term_db);
  $term_db = preg_replace("\[\[:>:\]\]", "", $term_db);

  $terms_db_no_word_boundaries[] = $term_db;
}

?>[/code]

Orio.

OK thanks for your help, I've got it working with forward slashes at the start and end of the search string as well as the backslashes before the "[" and "]" symbols:

foreach($terms_db as $term_db)
{
  $term_db = preg_replace("/\[\[:<:\]\]/", "", $term_db);
  $term_db = preg_replace("/\[\[:>:\]\]/", "", $term_db);

  $terms_db_no_word_boundaries[] = $term_db;
}
