README

PHP Fast XML Parser is a PHP library for parsing large XML files using PHP. Key features:

• Lightweight;
• Flexible (result can be easily managed via callback handlers);
• Good for memory critical projects (~10Mb in average while parsing 500mb XML file)

Installation

composer require alex.oleshkevich/fast-xml-parser 

Example & Tutorial

<?php declare(strict_types=1); require_once("vendor/autoload.php"); use FastXml\CallbackHandler\GenericHandler; use FastXml\Parser; // create callback handler $handler = new GenericHandler; // set "on item parsed" callback $handler->setOnItemParsedCallback(function ($item) use ($self) { // do smth with parsed item }); // set "on progress" callback $handler->setOnProgressCallback(function ($bytesProcessed, $bytesTotal) use ($self) { // eg. draw a progress bar }); // instantiate $parser = new Parser($handler); // define tags which you don't want to include in resulting array (optional) $parser->setIgnoreTags(['root']); // define end tag for every item // (this is used as marker to determine when XML // item was processed. // For example, if you want to extract "value" from this XML source //<root> // <value>VALUE</value> // <value>VALUE</value> // <value>VALUE</value> //</root> // you must call $parser->setEndTag('value') so library can // emit content of every <value /> tag in "onItemParsed" event. $parser->setEndTag('value'); // run $parser->parse('bigfile.xml');
