I have my working code which extracts the title from a string, but right now it still isn’t very flexible.
Current code:
$post_title = "THIS IS A TEST - 10-01-2010 - HELLO WORLD (OKAY)!!"; $post_title = substr($post_title, 0, strpos($post_title, '-') - 1);
I want to get the title of the string, which is at the start of the string and goes until the first dash. I don’t want to get the spaces before the dash and it could be that there is no dash at all.
The output of the current code works and outputs THIS IS A TEST
, but the current code doesn’t work for the following cases, so I need a more flexible code:
- THIS IS A TEST – 10-01-2010 – HELLO WORLD (OKAY)!!
- THIS IS A TEST-10-01-2010 – HELLO WORLD (OKAY)!!
- THIS IS A TEST – – – – 10-01-2010 – HELLO WORLD (OKAY)!!
- THIS IS A TEST
So the title can exist without a -
and someone could forget to put a space between the -
, equally, someone could put too many spaces.
The output for all the above cases should always be THIS IS A TEST
with no spaces at the end.
With the code I have, the only one that works is the first one.
$title= explode('-', $post_title); $post_title=trim($title[0]); $trimmedTitle=$post_title; $str = "THIS IS A TEST -0-01-2010 - HELLO WORLD (OKAY)!!"; preg_match("/^([ws]+)s*-?/m", $str, $m); print_r($m);

Answer
Use explode() with the “-” as a delimiter to split it into chunks based on the presence of the “-” and then take the first portion and use trim() to trim the trailing spaces to give the title with no trailing spaces. This gives “THIS IS A TEST” in all the provided test cases. If there are no dashes then the entire string is returned.
<?php $str = 'THIS IS A TEST - 10-01-2010 - HELLO WORLD (OKAY)!!'; $title= explode('-', $str); $trimmedTitle=trim($title[0]); print_r($trimmedTitle); //$trimmedTitle ='THIS IS A TEST ?>
I have tested this against:
THIS IS A TEST - 10-01-2010 - HELLO WORLD (OKAY)!! THIS IS A TEST-10-01-2010 - HELLO WORLD (OKAY)!! THIS IS A TEST - - - - 10-01-2010 - HELLO WORLD (OKAY)!! THIS IS A TEST
and each returns THIS IS A TEST with no trailing spaces
