Dump SQLite database to .sql with PHP alone

I have a webapp on my phone what uses SQLite, and I have no sqlite3 tool that I can call from CLI, so I needed a pure-PHP solution to dumping my database.

Nothing on the internet seems to be created for this purpose, or at least nothing that can be found in the first page of google.

So well, if this page won’t end up on the first page of google I’m just wasting my time.

Dammit.

So anyway:

<?php

$db = new SQLite3(dirname(__FILE__)."/your/db.sqlite");
$db->busyTimeout(5000);

$sql="";

$tables=$db->query("SELECT name FROM sqlite_master WHERE type ='table' AND name NOT LIKE 'sqlite_%';");

while ($table=$tables->fetchArray(SQLITE3_NUM)) {
	$sql.=$db->querySingle("SELECT sql FROM sqlite_master WHERE name = '{$table[0]}'").";\n\n";
	$rows=$db->query("SELECT * FROM {$table[0]}");
	$sql.="INSERT INTO {$table[0]} (";
	$columns=$db->query("PRAGMA table_info({$table[0]})");
	$fieldnames=array();
	while ($column=$columns->fetchArray(SQLITE3_ASSOC)) {
		$fieldnames[]=$column["name"];
	}
	$sql.=implode(",",$fieldnames).") VALUES";
	while ($row=$rows->fetchArray(SQLITE3_ASSOC)) {
		foreach ($row as $k=>$v) {
			$row[$k]="'".SQLite3::escapeString($v)."'";
		}
		$sql.="\n(".implode(",",$row)."),";
	}
	$sql=rtrim($sql,",").";\n\n";
}
file_put_contents("sqlitedump.sql",$sql);

Or just find, edit, comment the code on GitHub.
