php怎么将一个二维数组拆分成几个数组

怎么将下面二维数组拆分成几个数组 $arr = array(array('id' => 1,'user_name'=>'test1'),array('id' => 2,'user_name'=>'test2'),array('id' => 3,'user_name'=>'test3'),,array('id' => 4,'user_name'=>'test2'),array('id' => 5,'user_name'=>'test3') ); 拆分后,个数不一定，每组2个或者3个不一定 $arrnew[0] = array( array( 'id' => 1, 'user_name'=>'test1' ), array( 'id' => 2, 'user_name'=>'test2' ) );$arrnew[1] = ar...

extractdataPHPextract将数组拆分成多个变量的函数

extract()函数语法： int extract( array $var_array [, int $extract_type = EXTR_OVERWRITE [, string $prefix ]] ) 功能： extract()函数提取关联数组(对数字索引数组无效)每对key和value，生成以key为变量名、value为对应值的多组新变量。代码如下:$size = "old size"; //注意最后size变量的值。 $a = array( "color" => "red", "size" => "XXL", "price" => "53"); extract($a); echo "color = $color"; echo "size = $size...

PHPextract()函数用法php数组拆分

PHPextract()函数(数组拆分)定义与用法

$a = 'Original'; $my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse"); extract($my_array); echo "\$a = $a; \$b = $b; \$c = $c"; ?>输出： $a = Cat; $b = Dog; $c = Horse 例子 2 使用全部参数： $a = 'Original'; $my_array = array("a" => "Cat","b" => "Dog", "c" => "Horse");extract($my_array, EXTR_PREFIX_SAME, 'dup');echo "\$a = $a; \$b = $b; \$c = $c; \$dup_a = $dup_a;"; ?>输出： $a = Origin...

PHPextract数组拆分成多个变量

$size = "old size"; //注意最后size变量的值。 $a = array( "color" => "red", "size" => "XXL", "price" => "53"); extract($a); echo "color = $color"; echo "size = $size"; echo "price = $price"; ?> 输出结果: color = red size = XXL price = 53 通过上例发现$size的值为XXL，而不是之前的”old size”，说明默认情况下当数组中的key与已有的变量冲突时，将覆盖原来的变量。继续介绍extract函数的后两个可选参数。第...
