XSLTProcessor::setParameter — Set value for a parameter

说明

public XSLTProcessor::setParameter(string $namespace, string $name, string $value): bool
public XSLTProcessor::setParameter(string $namespace, array $options): bool

Sets the value of one or more parameters to be used in subsequent transformations with XSLTProcessor. If the parameter doesn't exist in the stylesheet it will be ignored.

参数

namespace

The namespace URI of the XSLT parameter.

name

The local name of the XSLT parameter.

value

The new value of the XSLT parameter.

options

An array of name => value pairs.

返回值

成功时返回 true， 或者在失败时返回 false。

错误／异常

Throws a ValueError if any of the arguments contain null bytes.

更新日志

版本 说明
8.4.0 Now throws a ValueError if any of the arguments contain null bytes instead of silently truncating.
8.4.0 It is now possible to set a parameter value containing both single and double quotes. Prior to PHP 8.4.0, this resulted in a warning.

示例

示例 #1 Changing the owner before the transformation

<?php

$collections = array(
'Marc Rutkowski' => 'marc',
'Olivier Parmentier' => 'olivier'
);

$xsl = new DOMDocument;
$xsl->load('collection.xsl');

// Configure the transformer
$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl); // attach the xsl rules

foreach ($collections as $name => $file) {
// Load the XML source
$xml = new DOMDocument;
$xml->load('collection_' . $file . '.xml');

$proc->setParameter('', 'owner', $name);
$proc->transformToURI($xml, 'file:///tmp/' . $file . '.html');
}

?>
