使用php操作对象数组中的字符串 - Manipulate string in array of objects with php

Manipulate string in array of objects with php

我有stdClass数组:

array (size=2)
  0 => 
    object(stdClass)[2136]
      public 'id' => string '1946' (length=4)
      public 'office' => string 'test' (length=4)
      public 'level1' => string 'test level 1' (length=12)
  1 => 
    object(stdClass)[2135]
      public 'id' => string '1941' (length=4)
      public 'office' => string 'test' (length=4)

如何用span标签包装每个'test'值

foreach ($array as $stdClass)
    foreach ($stdClass as &$value) // reference
        if ($value === "test")
            $value = "<span>".$value."</span>";

简单地遍历数组和类，因为它们都可以用foreach迭代。(通过引用迭代类，否则不会更改)

要在span中包装与单词'test'匹配的所有对象值，您将需要遍历对象属性以及数组本身。你可以使用foreach:

foreach ($object in $array) {
    foreach ($property in $object) {
        if ($object->$property == 'test') {
            $object->$property = "<span>{$object->property}</span>";
        }
    }
}

如果您想用span将单词test的所有实例包装在属性值中，您可以使用preg_replace，如下所示:

foreach ($object in $array) {
    foreach ($property in $object) {
        $object->$property = preg_replace('/'b(test)'b/', '<span>$1</span>', $object->$property);
    }
}

给定字符串"This test is for testing purposes as a test"，上述调用将输出如下内容:

This <span>test</span> is for testing purposes as a <span>test</span>.
