标题几乎是不言自明的...
我想删除所有空格，除非它位于" "或''
例如：
<?php
$myText = <<<EOF
echo 'Those spaces should not be removed'; echo 'but the spaces between the semicolon TO the next echo should be removed';
EOF;
$string = str_replace(' ', '', $myText); //this remove everything :(
?>
我预计$string是：
echo'Those spaces should not be removed';echo'but the spaces between the semicolon TO the next echo should be removed';
谢谢！
试试这个：
// Break up $string into an array of separated $string_parts
while (preg_match('/''';[^'']+''/', $string)) {
preg_match('/''';[^'']+''/', $string, $pattern);
$string_explode = explode($pattern[0], $string);
$string_parts[] = $string_explode[0];
$string_parts[] = $pattern[0];
$string = $string_explode[1];
}
// Add last remaining part of original $string to $string_parts array
$string_parts[] = $string_explode[1];
// Collapse the spaces in every second element in $string_parts array
$count_string_parts = count($string_parts);
for ($i = 1; $i < $count_string_parts; $i = $i + 2) {
$string_parts[$i] = str_replace(' ', '', $string_parts[$i]);
}
// Put $string back together again from $string_parts array
$string = implode($string_parts);
