Use PHP var_export API to dump data to file

Milo的海域 — Tue, 10 Apr 2012 02:54:00 GMT

Some time we may not want export complex hash to console but file, we can do like this to dump to file by var_export

php

$a = array('abc'=>"123");

# var dump
var_dump($a);

# var_export
echo var_export($a);

# export to file
$b = var_export($a, true);
error_log($b."\n", 3, "/tmp/ymiao.log");

Result:

cat /tmp/ymiao.log

array (
'abc' => '123',
)
