Re: [phplib] php4.0.4 and phplib template problems. From: Ben Curtis (benc <email protected>)

I just had this problem last night/this morning when moving a code base from test on 4.0.3pl1 to production 4.0.4. I experienced exactly what you described here - a template with ${varname} in a block (and only in a block) loses the first two digits of the value stuffed into varname. Luckily we got the bright idea to add a space after the $ to fix the problem. I'm just adding my vote to get this fixed properly and quickly. :)
