simplexml_load_stringの使い方 2

<h3>xml</h3>
<?php

$axmlData = array();
$axmlData&#91;0&#93; = array 
		(
			"name"=> "楽天日本株4.3倍ブル",
			"rate" => "123.54",
			"asset" => "27625"
		);
$axmlData[1] = array
		(
			"name" => "小型株ファンド",
			"rate" => "107.11",
			"asset" => "24381"
		);
$sStringXML = '<?xml version="1.0" encoding="UTF-8"?>'."\n";
echo $axmlData[0][rate];
$sStringXML .= "<list>"."\n";
foreach($axmlData as $value){
	$sStringXML .= "<item>";
	$sStringXML.= "<return>".$value['rate']."</return>";
	$sStringXML .= "<toshin>".$value['name']."</toshin>";

	$sStringXML .= "<shisan>".$value['asset']."</shisan>";
	$sStringXML .= "</item>"."\n";
}
$sStringXML .= "</list>"."\n";
echo '[PHP ruler="true" toolbar="true"]'.htmlentities($sStringXML, ENT_QUOTES, 'UTF-8').'<\/pre>';
echo "<br>";
$xml = simplexml_load_string($sStringXML);

foreach($xml->item as $value){
	$name = $value->toshin;
	$return = $value->return;
	$asset = $value->shisan;

	echo 'name:'.$name.'<br/>';
	echo 'return:'.$return.'<br/>';
	echo 'asset:'.$asset.'<br>';
}
?>

name:楽天日本株4.3倍ブル
return:123.54
asset:27625
name:小型株ファンド
return:107.11
asset:24381

つまり、下記のxml：return, toshin, shisanを切り取ってくれるということですね。

<?xml version="1.0" encoding="UTF-8"?> <list> <item><return>123.54</return><toshin>楽天日本株4.3倍ブル</toshin><shisan>27625</shisan></item> <item><return>107.11</return><toshin>小型株ファンド</toshin><shisan>24381</shisan></item> </list>

htmlentities()

文字列をhtmlエンティティ化

<?php

$str = "<!DOCTYPE html>"
	. "<html>"
	. "<head>"
	. "<meta charset='utf-8'>";

var_dump(htmlentities($str));
?>

エンティティ化しないと、string(49) “”

xml作成

<h3>xml</h3>
<?php

$axmlData = array();
$axmlData&#91;0&#93; = array 
		(
			"name"=> "楽天日本株4.3倍ブル",
			"return" => "123.54%",
			"asset" => "27625"
		);
$axmlData[1] = array
		(
			"name" => "小型株ファンド",
			"return" => "107.11%",
			"asset" => "24381"
		);
$sStringXML = '<?xml version="1.0" encoding="UTF-8"?>'."\n";
$sStringXML .= "<list>"."\n";
foreach($axmlData as $value){
	$sStringXML .= "<item>";
	$sStringXML .= "<name>".$value['name']."</name>";
	$sStringXMl .= "<return>".$value['return']."</url>";
	$sStringXML .= "<asset>".$value['asset']."</asset>";
	$sStringXML .= "</item>"."\n";
}
$sStringXML .= "</list>"."\n";
echo '[PHP ruler="true" toolbar="true"]'.htmlentities($sStringXML, ENT_QUOTES, 'UTF-8').'<\/pre>';

xml

[PHP ruler="true" toolbar="true"]<?xml version="1.0" encoding="UTF-8"?> <list> <item><name>楽天日本株4.3倍ブル</name><asset>27625</asset></item> <item><name>小型株ファンド</name><asset>24381</asset></item> </list> <\/pre>

なんか違うな。。

文字列演算子 .=

文字列を「.」で繋げると結合

<?php

$fx = "ドル円";
$fx .= "106.301";

echo $fx;
?>

ドル円106.301

<?php

$rate = array(106.31, 131.908, 84.080);

$fx = "ドル円";
$fx .= $rate&#91;0&#93;;
$fx .= "ユーロ円";
$fx .= $rate&#91;1&#93;;
$fx .= "豪ドル円";
$fx .= $rate&#91;2&#93;;

echo $fx;
?>

ドル円106.31ユーロ円131.908豪ドル円84.08

object(simpleXMLElement) = simplexml_load_string(xmlchar)

xml文字列を作成し、その文字列をsimplexml_load_string()関数で、オブジェクトに代入。
そのオブジェクトを展開することで、xmlデータを取得できる。
