php字符串合并,php字符串合并函数

PHP字符串的合并和重组

$tmpArray = array();

foreach ($laArray as $row) {

$key = $row['name'] . $row['age'];

if (array_key_exists($key, $tmpArray)) {

$tmpArray[$key]['id'] = $tmpArray[$key]['id'] . '+' . $row['id'];

if (is_array($tmpArray[$key]['moeny'])) {

$tmpArray[$key]['moeny'][] = $row['moeny'];

} else {

$tmpArray[$key]['moeny'] = array($tmpArray[$key]['moeny'], $row['moeny']);

}

} else {

$tmpArray[$key] = $row;

}

}

echo "pre";

var_dump($tmpArray);

php怎样把两行字符串合并成一行?如下：

我是没看出有啥意义，如果是输出的话有两个

$str='athis isbr /php/a';

$str="athis is \n php/a";

php中怎么将两个字符串合并成一个

?php

$a="abc";

$b="def";

$c=$a.$b;

echo $c; //这时候的$c=“abcdef”

?

php分割两个字符串合并，并且一组一组显示？

z1 = '1@@2##3@@4##5@@6##7@@8';

$z2 = '一$$二$$三';

$z1Arr = explode('##', $z1);

$z2Arr = explode('$$', $z2);

$html = '';

foreach ($z1Arr as $key = $value) {

$data = explode('@@', $value);

$html .= 'span' . $data[0] . '/spanb'.$data[1].'/b' . (isset($z2Arr[$key])? 'em'.$z2Arr[$key].'/em' : '');

}
