要調(diào)試PHP數(shù)組操作,您可以使用以下方法:
print_r()
或var_dump()
函數(shù)打印數(shù)組,以便查看其結(jié)構(gòu)和內(nèi)容。$array = array("apple", "banana", "cherry");
echo "<pre>";
print_r($array);
echo "</pre>";
var_export()
函數(shù)導(dǎo)出數(shù)組為字符串,便于查看和編輯。$array = array("apple", "banana", "cherry");
echo var_export($array, true);
error_reporting()
和ini_set()
函數(shù)報(bào)告錯(cuò)誤。error_reporting(E_ALL);
ini_set('display_errors', 1);
$array = array("apple", "banana", "cherry");
breakpoint(); // 此處設(shè)置斷點(diǎn)
$array = array("apple", "banana", "cherry");
file_put_contents("array.log", print_r($array, true));
class ArrayTest extends PHPUnit\Framework\TestCase {
public function testArrayContents() {
$array = array("apple", "banana", "cherry");
$this->assertEquals(3, count($array));
$this->assertTrue(in_array("apple", $array));
}
}
通過使用這些方法,您可以更輕松地調(diào)試PHP數(shù)組操作并找到潛在問題。
