Can anyone confirm that 2.4.7's /dev/build fails with PHP 5.4. I get a notice "Array to string conversion" and backtrace tells me it's in Line 327 of Database.php: SS_Database->requireIndex(ErrorPage_versions,RecordID_Version,Array)

I read that php 5.4 no longer silently accepts array to string conversion, the idea being that it should warn against useless casting (or something of that nature)

I guess silverstripe will work when php warnings are disabled, but this should maybe be patched/looked into if version 2 is to be continued alongside 3? There might be other places where this might happen as well?

Hi smares
I confirm. PHP 5.4.3
My error is in Line 162 of SSViewer.php

162 		if(substr((string) $templateList,-3) == '.ss') {
163 			$this->chosenTemplates['main'] = $templateList;
164 		} else {
165 			if(!is_array($templateList)) $templateList = array($templateList);
166 			
167 			if(isset($_GET['debug_request'])) Debug::message("Selecting templates from the following list: " . implode(", ", $templateList));
 

Simply change

if(substr((string) $templateList,-3) == '.ss') {

to

if(is_string($templateList) && substr((string) $templateList,-3) == '.ss') {

Though not sure if 2.4 'officially' supports PHP5.4

This may be of some help:

Should I be having the same issue with 3.0.2 and PHP 5.3? Just get a blank white page (rest of site shows up fine)

Not sure if it's related but the installation gives the false mod_rewrite and AllowOverride All issues with Friendly URLs.

Thanks

we have the same problem occurring again n again.

I upgraded from 3.0.2 to the daily build and that fixed the dev/build issues.
