Variable Within Regex

[member123]

I'm trying to use a column of regular expressions in a MySQL table to check for certain phrases in a block of text.

 

I am creating an array with the column of data and then using a foreach loop to try out each row.

 

The regular expressions need to include a variable, because I am using this with another array of words.

 

What syntax do I use with the preg_match function and the column of regex values if I want to include a variable?

I think you got the method wrong some how?

 

If you want to use a regex agin and agin, you need to create a function for the regex mate...

 

You call the function each time you need to re-use the current regex.....

I'm using the preg_match function.  I'm feeding it the same regex each time, except the variable embedded in the regex is changing each time.

please provide your current example........

	$posregexes = array('/' .$variant . '\\s+(wins)\\s+(series)/',
				'/$variant\\s+(hires)\\s+(player)/'
			);


			foreach($posregexes as $regex) {
			echo $regex . "<br />";
			echo $variant;
				if (preg_match ($regex, $shebang))
    					{
    						$tags[] = 'positive';
    					}
			}
			foreach($negregexes as $regex) {
			echo $regex . "<br />";
			echo $variant;
				if (preg_match ($regex, $shebang))
    					{
    						$tags[] = 'negative';
    					}
			}
	}

 

$variant is itself the output from an outer foreach loop, so its value will be different each time this code is run.

Anybody know what syntax I'm supposed to use for the embedded variable?

It has to be in double quotes so the variable is parsed.
