改写函数实现PHP二维/三维数组转字符串_php技巧

//将多维数组中所有的数值转换成字符串————》最多支持三维数组 
function implodex( $glue, $array, $separator='' ) { 
if ( ! is_array( $array ) ) return $array; 
$string = array(); 

$count = 0; 
foreach ( $array as $key => $val ) { 
if ( is_array( $val ) ) 
$val = implode( $glue, $val ); 

if($count == 0){ 
$string[] = "{$val}"; 
}else{ 
$string[] = "{$glue}{$val}"; 
} 
} 

if(empty($separator))$separator = $glue; 

return implode( $separator, $string ); 
}
