php implode breaks on spaces

I have an array of strings, and these strings have spaces in them. For example:

$arr = array('bob', 'john smith', 'grease monkey', 'etc');

Why is it when I try to $str = implode('|', $arr);, it stops at the first space it finds?? I'm left with a string like:

$str = "bob|john";开发者_如何学JAVA

If I try:

$arr = array('bob', 'john', 'grease monkey', 'etc');

and implode, I get:

$str = "bob|john|grease";

Edit: I'm actually trying to set it to the value of a hidden field:

<input id="hidLblFields" name="hidLblFields" type="text" value=<?php echo implode('|', $myFields);?> />

<input id="hidLblFields" name="hidLblFields" type="text" value=<?php echo implode('|', $myFields);?> />

You need to quote the value attribute:

<input .. type="text" value="<?php echo implode('|', $myFields);?>" />

Without doing that, the rendered HTML looks like:

<input type="text" value=bob|john|grease monkey />

Which the browser will handle as this:

<input type="text" value="bob|john|grease" monkey />

You must have an error somewhere else in your code, implode() does not break on spaces.

$arr = array('bob', 'john', 'grease monkey', 'etc');
$str = implode('|', $arr);
var_dump($str);
// gives
string(26) "bob|john|grease monkey|etc"

As for your edit, you need quotes around attributes in html:

<input id="hidLblFields" name="hidLblFields" type="text" value="<?php echo implode('|', $myFields);?>" />

This is simply not possible. You have some other functions doing some other operations

Worked for me. Try not reassigning your variables:

<?php 
$str = array('bob', 'john smith', 'grease monkey', 'etc');
$new_str = implode('|', $str);

echo $new_str;
?>
