What does it mean?

Hi,
Can anybody help me with working out what this expression actually does. Am not very familiar with reg expr.
[code]$expression =  "/\'{1,}\"\.{2,}/";[/code]


Thanks
Jan

I'm not an expert either in this field but what I think it is doing is this
[b]/[/b] - this is the stating delimiter every reqular expression requires a starting/ending delimiter
[b]\'{1,}[/b] - this says find 1 or more instance of [b]'[/b]
[b]\"\.{2,}[/b] - this says find 2 or more instances of [b]".[/b]
[b]/[/b] - this is the ending delimiter

Almost.

[code]/ # Open delimiter
\'{1,} # One or more instances of '. {1,} is better written as +
\" # A double quote
\.{2,} # Two or more instances of any character except a new line.
/ # Close delimiter[/code]
