php foreach循环无法提供所有结果吗？

Question

我正在尝试从字符串中获取指定的单词。

我不知道我是否忘记了什么，但是它仅显示前两个值？有人可以帮我吗？

感谢您的帮助！

$orgData["connector"] = 'some stringy thing SMA-female N-female FME-female';

if (preg_match_all('/(N-female|SMA-female|FME-female)/',$orgData["connector"], $matches)) {
    foreach ($matches as $i => $match) {
        if ($match[$i] == "N-female") {
            $con1 = "|Connector: N-female";
        }
        if ($match[$i] == "SMA-female") {
            $con2 = "|Connector: SMA-female";
        }
        if ($match[$i] == "FME-female") {
            $con3 = "|Connector: FME-female";
        }
        print_r($con1 . $con2 . $con3);
    }
}

您可以使用单个变量，并在找到匹配项后追加：

@Entity
@Table(name="worktime")
public class Worktime {

    @Id
    @Column(name="worktime_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int worktimeId;

    @Column(name="date")
    @Temporal(TemporalType.DATE)
    private Date date;

    @ElementCollection
    @CollectionTable(name="WORKTIME_TIMES")
    @Temporal(TemporalType.TIME)
    private List<Date> startTimes = new ArrayList<>();

    @ElementCollection
    @CollectionTable(name="WORKTIME_TIMES")
    @Temporal(TemporalType.TIME)
    private List<Date> endTimes = new ArrayList<>();

    @ManyToOne
    @JoinColumn(name="person_id")
    private Employee employee;
 ...
}

请参见。

请注意，我会简化模式：$orgData = 'some stringy thing SMA-female N-female FME-female'; $con = ""; if (preg_match_all('/(?:N|SMA|FME)-female/', $orgData, $matches)) { foreach ($matches[0] as $match) { if ($match == "N-female") { $con .= "|Connector: N-female"; } if ($match == "SMA-female") { $con .= "|Connector: SMA-female"; } if ($match == "FME-female") { $con .= "|Connector: FME-female"; } } } echo $con; // => |Connector: SMA-female|Connector: N-female|Connector: FME-female 匹配(?:N|SMA|FME)-female，N或SMA，然后匹配FME。
