When drawing in PHP, the characters called exceed the picture border. How to fix line breaks?
Answer
I hope it can automatically wrap after reaching a certain number of bytes,
It should be around row 3. How do I write a line break?
$content (content)
I hope to achieve automatic line wrapping after reaching the number of characters displayed in one row
The second row also follows suit! I searched Google/Baidu for a long time and found no questions about parts of speech
Of course the answer is hard to find. Specially come to PHP to ask questions
Currently using:
if (strlen($content)>38) {
$content1=get_substr($content,0,38);
$content2=get_substr($content, 38,23);
$content3=get_substr($content,37,23);
if ($content3!=$content2)
$content2=$content3;
$content=$content1."n".$content2."...";
}
function get_substr($string,$start='0',$length='')
{
$start = (int)$start;
$length = (int)$length;
$i = 0;
if(!$string)
{return;}
if($start>=0) {
while($i
if(ord($string[$i])>127) {
$i = $i+2;
} else {
$i++;
}
}
$start = $i;
if($length=='') {
return substr($string,$start);
}
elseif($length>0) {
$end = $start+$length;
while($i
if(ord($string[$i])>127) {
$i = $i+2;
} else {
$i++;
}
} if($end != $i-1) {
$end = $i;
} else {
$end--;
}
$length = $end-$start;
return substr($string,$start,$length);
} elseif($length==0) {
return;
} else {
$length = strlen($string)-abs($length)-$start;
return get_substr($string,$start,$length);
}
} else {
$start = strlen($string)-abs($start);
return get_substr($string,$start,$length);
}
}
This is very inflexible. I hope the experts can provide a more convenient way! Thanks!
For example, I want to achieve:
Signature: +$content+time
Specific situation:
Signature: If you hesitate again

How can I achieve this effect?
It feels like it is divided into three tags
Tag 1: Custom text
Tag 2: Specific content
Tag 3: Release time
Combined, they can be displayed neatly in a fixed block
Just like Taotao on QQ: [img]http://p.taotao.com/images/head/79/45/00/16/79450016_2.png[/img]
Just like this effect. In fact, I also want to do this kind of thing! It’s the content that’s causing the problem!
Is the ultimate goal to achieve the kind of picture-making effect that is so great? [img]http://www.111cn.cn/bbs/images/smilies/default/loveliness.gif[/img][img]http://www.111cn.cn/bbs/images/smilies/default/loveliness .gif[/img]
