Generator::throw — 向生成器中抛入一个异常
抛出一个异常到生成器并恢复生成器的执行。
与当前 yield 表达式被 throw $exception 语句替换是一样的行为。
如果调用此方法时生成器已经关闭，则将会在调用者的上下文中抛出异常。
exception抛出异常到生成器。
返回生成的值。
示例 #1 抛出异常到生成器
<?php
function gen() {
echo "Foo\n";
try {
yield;
} catch (Exception $e) {
echo "Exception: {$e->getMessage()}\n";
}
echo "Bar\n";
}
$gen = gen();
$gen->rewind();
$gen->throw(new Exception('Test'));
?>以上示例会输出：
Foo Exception: Test Bar
$gen = (function () {
try {
yield 1;
} catch (Exception $e) {
echo $e->getMessage();
}
})();
$gen->throw(new Exception('gen throw exception'));$gen = (function () {
try {
yield 1;
} catch (Exception $e) {
echo $e->getMessage();
}
})();
$gen->throw(new Exception('gen throw exception'));there have errors the form correct to do that is of this way:
function gen() {
echo "Foo\n";
try {
throw new Exception('Prueba');
} catch (Exception $e) {
echo "Excepción: {$e->getMessage()}\n";
}
echo "Bar\n";
}
gen();
i resolved one tecnic of how work getMessage look at it:
$myarray=array();
if($respuesta == "Mark"){
for($i=5;$i<=16;$i++){
try {
$palabra="soy la excepcion en la linea:".$i;
throw new Exception($palabra);
}
catch(Exception $e) {
$myarray[$e->getLine()] =$palabra;
if($e->getLine() == $i){
echo "<br><b>La excepción se creó en la línea : " .$e->getLine()."LA LINEA DICE:". $myarray[$e->getLine()]."</b>";
}//if
}//catch
}//for
}//if
