我们在搜索一些东西时会经常遇到可以通过空格隔开来达到输入多个条件的目的。今天正好项目中遇到了这个情况,就写了一个函数,将多个条件放到数组里。目前支持空格、逗号(中英文)、回车分割,如不能满足需求,看下这个函数修改一下应该就可以了
复制代码 代码如下:
/**
* transform ' hello, world !' to array('hello', 'world')
*/
function strsToArray($strs) {
$result = array();
$array = array();
$strs = str_replace(',', ',', $strs);
$strs = str_replace("n", ',', $strs);
$strs = str_replace("rn", ',', $strs);
$strs = str_replace(' ', ',', $strs);
$array = explode(',', $strs);
foreach ($array as $key => $value) {
if ('' != ($value = trim($value))) {
$result[] = $value;
}
}
return $result;
}
//test
$strs = 'Code is poetry! WTF!';
var_dump(strsToArray($strs));

php将16进制字符串转为数字的方法:1、使用hexdec()函数,语法“hexdec(十六进制字符串)”;2、使用base_convert()函数,语法“bindec(十六进制字符串, 16, 10)”。

PHP 是一门功能强大的编程语言,广泛应用于 Web 开发领域。其中一个非常常见的情况是需要将字符串转换为小数。这在进行数据处理的时候非常有用。在本文中,我们将介绍如何在 PHP 中将字符串转换为小数。

检测变量是否为字符串的方法:1、利用“%T”格式化标识,语法“fmt.Printf("variable count=%v is of type %T \n", count, count)”;2、利用reflect.TypeOf(),语法“reflect.TypeOf(变量)”;3、利用reflect.ValueOf().Kind()检测;4、使用类型断言,可以对类型进行分组。

php字符串长度不一致的解决办法:1、通过mb_detect_encoding()函数查看字符串的编码方式;2、通过mb_strlen函数查看具体字符长度;3、使用正则表达式“preg_match_all('/[\x{4e00}-\x{9fff}]+/u', $str1, $matches);”剔除非中文字符即可。

删除方法:1、使用TrimSpace()函数去除字符串左右两边的空格,语法“strings.TrimSpace(str)”;2、使用Trim()函数去除字符串左右两边的空格,语法“strings.Trim(str, " ")”;3、使用Replace()函数去除字符串的全部空格,语法“strings.Replace(str, " ", "", -1)”。

在开发PHP应用程序时,有时我们需要去掉字符串前面的某些特定字符或者字符串。在这种情况下,我们需要使用一些PHP函数来实现这一目标。本文将介绍一些PHP函数,帮助您轻松地去掉字符串前面的字符或字符串。

转换方法:1、在转换变量前加上用括号括起来的目标类型“(bool)”或“(boolean)”;2、用boolval()函数,语法“boolval(字符串)”;3、用settype()函数,语法“settype(变量,"boolean")”。

php字符串部分乱码的解决办法:1、使用“mb_substr(strip_tags($str),0,-1,'UTF-8');”截取字符串;2、使用“iconv("UTF-8","GB2312//IGNORE",$data)”转换字符集即可。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
