Description: I am very new to PHP and I was so happy to figure out how to do this, after reading much “almost there” code & function descriptions. If anyone needs the output of a class/array/var to a file, instead of a display, this works great.

$classvar =  Class::someFunc($otherobj->runAQuery()) ; 

#start buffering (all activity to the buffer)
ob_start() ;

# dumps to buffer
var_dump($classvar) ;

# dump buffered $classvar to $outStringVar
$outStringVar = ob_get_contents() ;

# open your file with append, read, write perms
# (be sure to check your file perms)

# write output to file & close it
fwrite($fp, $outStringVar );

# clean the buffer & stop buffering output
ob_end_clean() ;
